Herbgenomics is an emerging field of traditional Chinese medicine(TCM)research and development.By combining TCM research with genomics,herbgenomics can help to establish the scientific validity of TCM and bring it into wider usage within the field of medicine.Salvia Linn.(S.Linn.)is a large genus of Labiatae that includes important medicinal plants.In this herbgenomics study,the complete chloroplast(cp)genomes of two Salvia spp.—namely,S.przewalskii and S.bulleyana,which are used as a surrogate for S.miltiorrhiza—were sequenced and compared with those of two other reported Salvia spp.—namely,S.miltiorrhiza and S.japonica.The genome organization,gene number,type,and repeat sequences were compared.The annotation results showed that both Salvia plants contain 114 unique genes,including 80 protein-coding,30 transfer RNA(tRNA),and four ribosomal RNA(rRNA)genes.Repeat sequence analysis revealed 21 forward and 22 palindromic sequences in both Salvia cp genomes,and 17 and 21 tandem repeats in S.przewalskii and S.bulleyana,respectively.A synteny comparison of the Salvia spp.cp genomes showed a high degree of sequence similarity in the coding regions and a relatively high divergence of the intergenic spacers.Pairwise alignment and single-nucleotide polymorphism(SNP)analyses found some candidate fragments to identify Salvia spp.,such as the intergenic region of the trnV–ndhC,trnQ–rps16,atpI–atpH,psbA–ycf3,ycf1,rpoC2,ndhF,matK,rpoB,rpoA,and accD genes.All of the results—including the repeat sequences and SNP sites,the inverted repeat(IR)region border,and the phylogenetic analysis—showed that S.przewalskii and S.bulleyana are extremely similar from a genetic standpoint.The cp genome sequences of the two Salvia spp.reported here will pave the way for breeding,species identification,phylogenetic evolution,and cp genetic engineering studies of Salvia medicinal plants. 展开更多

Medicinal plants are the primary material basis for disease prevention and treatment in traditional Chinese medicine(TCM).The conservation and sustainable utilization of these medicinal plants is critical for the development of the TCM industry.However,wild medicinal plant resources have sharply declined in recent decades.To ameliorate the shortage of medicinal plant resources,it is essential to explore the development potential of the TCM industry in different geographical regions.For this purpose,we examined the spatial distribution of commonly used medicinal plants in China,the number of Chinese medicinal material markets,and the number of TCM decoction piece enterprises.Specifically,multispecies superimposition analysis and Thiessen polygons were used to reveal the optimal range for planting bulk medicinal plants and the ideal regions for building Chinese medicinal material markets,respectively.Furthermore,we quantitatively analyzed mismatches between the spatial distribution of commonly used medicinal plant richness,Chinese medicinal material markets,and TCM decoction piece enterprises.We found that the areas suitable for growing commonly used medicinal plants in China were mainly distributed in Hengduan Mountain,Nanling Mountain,Wuling Mountain,and Daba Mountain areas.The Thiessen polygon network based on Chinese medicinal material market localities showed there are currently fewer markets in southwestern,northwestern,and northeastern China than in central and southern China.TCM decoction piece enterprises are concentrated in a few provinces,such as Hebei and Jiangxi.We found that the distribution of commonly used medicinal plants,Chinese medicinal material markets and TCM decoction piece enterprises are mismatched in Henan,Shaanxi,Hunan,Hubei,Zhejiang,Fujian,Chongqing,and Xizang.We recommend strengthening development of the TCM industry in Henan,Hunan,Zhejiang,Shaanxi,Hubei,Chongqing,Fujian,and Xizang;building more Chinese medicinal material markets in southwestern,northwestern,and northeastern China;and establishing medicinal plant nurseries in resource-rich provinces to better protect and domesticate local medicinal plants. 展开更多

Objective: To investigate the larvicidal activity of Syzygium guineense(Myrtaceae)(S. guineense), Monodora myristica and Zanthoxylum heitzii(Rutaceae)(Z. heitzii) extracts against Aedes albopictus(Ae. albopictus).Methods: The larvicidal activity of the hydro-ethanolic extracts from these plant species was assessed at three different concentrations(50, 100 and 200 mg/L) on first-instar of Ae. albopictus larvae in comparison with untreated controls. Mortality rate was recorded daily for a period of 12 days. The values of LC_(50) and lethal time killing 50% of the tested individuals(LT_(50)) were calculated using the log-probit analysis.Results: The root extract of S. guineense exhibited the best activity with 100% mortality after 8 days of treatment at 200 mg/L, followed by the fruit extract of Z. heitzii with83.33% mortality at the same concentration. Nonetheless, larvae were most susceptible to the fruit extract of Z. heitzii both in terms of LC_(50)(39.89 mg/L) and LT_(50)(145.68 h). A statistically significant difference between the control and the group treated at 200 mg/L was noticed in all the extracts.Conclusions: The present study shows that the hydro-ethanolic extracts of S. guineense,Monodora myristica and Z. heitzii tested have significant larvicidal activity. These preliminary results are of great interest and some of these plant species can be proposed for the formulation of new bioinsecticides to control Ae. albopictus populations. 展开更多

Brucellosis is an old, infectious and common zoonosis whose causative agents are Gramnegative bacteria from the Brucella genus. Brucellosis is transmitted through direct contactwith infected animals or using unpasteurized dairy products of goats, pigs, camels, sheep,buffalo and cows. Brucellosis is still the most common zoonosis in the world, with mostof cases occurring in developing countries. Today, an approach to traditional medicine andmedicinal plants, especially with regards to the repeated recommendations of the World HealthOrganization, is a necessity. One-third of chemical drugs are produced by using plants andthere is a high potential to produce more drugs from plants. Medicinal plants are helpful inthe management of various conditions, especially bacterial diseases. Although there is notenough scientific evidence regarding the clinical effectiveness of herbal drugs for the treatmentof brucellosis, there is strong evidence on the antimicrobial effects of herbal drugs to preventinfection. Therefore, this article seeks to describe the antibacterial effects of some plantderived essential oils or extracts, so that they can serve as promising choices to develop newanti-Brucella medications, as suitable alternatives to conventional antibiotics for brucellosis, asmuch as possible, taking into account the benefits of these herbal drugs. 展开更多

Medicinal plants have played an essential role in the development of human culture. Medicinal plants are resources of traditional medicines and many of the modern medicines are produced indirectly from plants. This study illustrates the importance of traditional and modern medicines in the treatment and management of human diseases and ailments. It has been confirmed by WHO that herbal medicines serve the health needs of about 80 percent of the world’s population;especially for millions of people in the vast rural areas of developing countries. Meanwhile, consumers in developed countries are becoming disillusioned with modern health care and are seeking alternatives. Thymus vulgaris is a species of flowering plant in the mint family Lamiacea. Thymus is a widely used medicinal plant in food and pharmaceutical industries. Among different species of Thymus, Thymus vulgaris is used more than other species in therapeutic dosage forms. In Traditional medicine T. vulgaris is cultivated in many countries by most people especially in rural areas depending on herbal medicines to treat many diseases including inflammation-related ailments such as rheumatism, muscle swelling, insect bites, pains, etc. Also the modern medicine in essential oil of thyme has demonstrated that the compounds have shown anti-inflammatory, antioxidant, antibacterial and antifungal properties. In this review the objective is to consider the past and present value of medicinal plants such as Thymus vulgar is used in traditional and modern medical practices as bioactive natural compounds. 展开更多

Multi-drug resistant microbial infections caused by Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Salmonella typhi represent a critical public health issue worldwide. Plant-derived agents are credible sources for search and development of alternative antimicrobials to fight these infections. This study describes the in-vitro antibacterial activity of plants extracts from 15 medicinal plants of the Cameroonian pharmacopeia against Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Salmonella typhi. Plants selected based on their ethnopharmacological uses were extracted by either maceration or decoction using distilled water, ethanol, methanol and ethylacetate. The afforded extracts were phytochemically screened for bioactive secondary metabolites. The microdilution method was used to assess the antibacterial activity. The two promising extracts were tested in combination using the cbeckboard technique. Eighty one extracts showed antibacterial activity with eight having minimum inhibitory concentrations below 2.5 mg/mL. Results from combination assays with extracts from Terminalia catappa and Gnidia glauca leaves showed synergistic effect against Escherichia coli, Pseudomonas aeruginosa and Salmonella typhi and additive effect against Staphylococcus aureus. These extracts mainly contained saponins, tannins, glucosides, phenols, triterpenes and anthraquinones. These results support the ethnobotanical claims and indicate further directions for the investigation of plants extracts to develop alternative drugs against multi-resistant bacteria. 展开更多

Plants harbor diverse microbes(including bacteria,fungi,archaea,protists,and viruses)both inside and outside their tissues,so called the plant-associated microbiome.Decades of research have demonstrated the importance of plant microbiome in promoting the productivity and health of the plant in natural environment because of their essential functions in improving plant nutrition and plant resistance to biotic and abiotic stresses(Trivedi,Leach,Tringe,Sa,&Singh,2020).Thus,a plant can be regarded as a holobiont comprising the host plant and the associated microbiota(Hassani,Durán,&Hacquard,2018).Within the plant microbiota,mutualistic fungal and bacterial symbionts(e.g.mycorrhizal fungi and Rhizobia)are striking examples of microorganisms playing crucial roles in nutrient acquisition(Martin&van der Heijden,2024)and non-symbitic plant growth-promoting rhizobacteria or fungi(PGPR or PGPF)also have drawn interest due to their ability to improve soil properties and confer stress tolerance in plants(Upadhyay et al.,2023). 展开更多

Medicinal plants represent a huge reservoir of secondary metabolites(SMs),substances with significant pharmaceutical and industrial potential.However,obtaining secondary metabolites remains a challenge due to their low-yield accumulation in medicinal plants;moreover,these secondary metabolites are produced through tightly coordinated pathways involving many spatiotemporally and environmentally regulated steps.The first regulatory layer involves a complex network of transcription factors;a second,more recently discovered layer of complexity in the regulation of SMs is epigenetic modification,such as DNA methylation,histone modification and small RNA-based mechanisms,which can jointly or separately influence secondary metabolites by regulating gene expression.Here,we summarize the findings in the fields of genetic and epigenetic regulation with a special emphasis on SMs in medicinal plants,providing a new perspective on the multiple layers of regulation of gene expression. 展开更多

However, the potential of endophytes within these bio-prospective medicinal plants remains unknown. The present study elucidates the endophytic diversity of medicinal plants(Caralluma acutangula, Rhazya stricta, and Moringa peregrina) and the endophyte role in seed growth and oxidative stress. Various organs of medicinal plants yielded ten endophytes, which were identified as Phoma sp.(6 isolates), Alternaria sp.(2), Bipolaris sp.(1), and Cladosporium sp.(1) based on 18 S rD NA sequencing and phylogenetic analysis. The culture filtrates(CFs; 25%, 50%, and 100% concentrations) from these endophytes were tested against the growth of normal and dwarf mutant rice lines. Endophytic CF exhibited dose-dependent growth stimulation and suppression effects. CF(100%) of Phoma sp. significantly increased rice seed germination and growth compared to controls and other endophytes. This growth-promoting effect was due to the presence of indole acetic acid in endophytic CF. The gas chromatography/mass spectrometry(GC/MS) analysis showed the highest indole acetic acid content((54.31±0.21) μmol/L) in Bipolaris sp. In addition, the isolate of Bipolaris sp. exhibited significantly higher radical scavenging and anti-lipid peroxidation activity than the other isolates. Bipolaris sp. and Phoma sp. also exhibited significantly higher flavonoid and phenolic contents. The medicinal plants exhibited the presence of bio-prospective endophytic strains, which could be used for the improvement of crop growth and the mitigation of oxidative stresses. 展开更多

The worldwide botanical and medicinal culture diversity are astonishing and constitute a Pierian spring for innovative drug R&D.Here,the latest awareness and the perspectives of pharmacophylogeny and pharmacophylogenomics,as well as their expanding utility in botanical drug R&D,are systematically summarized and highlighted.Chemotaxonomy is based on the fact that closely related plants contain the same or similar chemical profiles.Correspondingly,it is better to combine morphological characters,DNA markers and chemical markers in the inference of medicinal plant phylogeny.Medicinal plants within the same phylogenetic groups may have the same or similar therapeutic effects,thus forming the core of pharmacophylogeny.Here we systematically review and comment on the versatile applications of pharmacophylogeny in(1)looking for domestic resources of imported drugs,(2)expanding medicinal plant resources,(3)quality control,identification and expansion of herbal medicines,(4)predicting the chemical constituents or active ingredients of herbal medicine and assisting in the identification and determination of chemical constituents,(5)the search for new drugs sorting out,and(6)summarizing and improving herbal medicine experiences,etc.Such studies should be enhanced within the context of deeper investigations of molecular biology and genomics of traditional medicinal plants,phytometabolites and metabolomics,and ethnomedicine-based pharmacological activity,thus enabling the sustainable conservation and utilization of traditional medicinal resources. 展开更多

This paper reports a pharmacophylogenetic study of a medicinal plant family,Ranunculaceae,investigating the correlations between their phylogeny,chemical constituents,and pharmaceutical properties.Phytochemical,ethnopharmacological,and pharmacological data were integrated in the context of the systematics and molecular phylogeny of the Ranunculaceae.The chemical components of this family included several representative metabolic groups:benzylisoquinoline alkaloids,ranunculin,triterpenoid saponin,and diterpene alkaloids,among others.Ranunculin and magnoflorine were found to coexist in some genera.The pharmacophylogenetic analysis,integrated with therapeutic information,agreed with the taxonomy proposed previously,in which the family Ranunculaceae was divided into five sub-families:Ranunculoideae,Thalictroideae,Coptidoideae,Hydrastidoideae,and Glaucidioideae.It was plausible to organize the sub-family Ranunculoideae into ten tribes.The chemical constituents and therapeutic efficacy of each taxonomic group were reviewed,revealing the underlying connections between phylogeny,chemical diversity,and clinical use,which should facilitate the conservation and sustainable utilization of the pharmaceutical resources derived from the Ranunculaceae. 展开更多

The Ranunculaceae genus Anemone(order Ranunculales),comprising more than 150 species,mostly herbs,has long been used in folk medicine and worldwide ethnomedicine.Various medicinal compounds have been found in Anemone plants,especially triterpenoid saponins,some of which have shown anti-cancer activities.Some Anemone compounds and extracts display immunomodulatory,antiinflammatory,antioxidant,and antimicrobial activities.More than 50 species have ethnopharmacological uses,which provide clues for modern drug discovery.Anemone compounds exert anticancer and other bioactivities via multiple pathways.However,a comprehensive review of the Anemone medicinal resources is lacking.We here summarize the ethnomedical knowledge and recent progress on the chemical and pharmacological diversity of Anemone medicinal plants,as well as the emerging molecular mechanisms and functions of these medicinal compounds.The phylogenetic relationships of Anemone species were reconstructed based on nuclear ITS and chloroplast markers.The molecular phylogeny is largely congruent with the morphology-based classification.Commonly used medicinal herbs are distributed in each subgenus and section,and chemical and biological studies of more unexplored taxa are warranted.Gene expression profiling and relevant "omics" platforms could reveal differential effects of phytometabolites.Genomics,transcriptomics,proteomics,and metabolomics should be highlighted in deciphering novel therapeutic mechanisms and utilities of Anemone phytometabolites. 展开更多
