The study verified that the mucilage cavities did exist in phloem of rhizomes and roots or abnormal vascular bundles. Also, they were in similar distribution in three species of Radix et Rhizoma Rhei. The diagnostic characteristic for microscopic identification was found to be the similar distribution of abnormal vascular bundles in pith of rhizomes in all three species. And the appearance of the crude drug varied more depending on the plants' geographical origin and different preliminary treatment on the spot of collection than on the species differences. Our findings, having not been delineated clearly so far in the previous reports, are helpful for clarifying current descriptions in different literatures or standards and make a full understanding on microscopic and macroscopic identification of Radix et Rhizoma Rhei.展开更多

METHODS: Samples of different ratios of Dahuang(Radix et Rhizoma Rhei Palnati, DH) to Taoren(Semen Persicae, TR)(Group A 1∶1, B 2∶3, C 3∶2) were analyzed based on gas chromatography time-of-flight mass spectrometry untargeted metabolomics technique. RESULTS: A total of 240 primary metabolites were detected. Forty-one differential metabolites involved nine differential metabolic pathways, of which four were closely related to the efficacy of DT in the treatment of heat and blood stasis syndrome. These pathways included the biosynthesis of amino acid(phenylalanine tyrosine and tryptophan), flavonoids, unsaturated fatty acids, and the glycolysis/glycogenesis pathway. CONCLUSION: There are significant differences in the efficacy of different ratios of DT drugs, and their optimal ratio for the treatment of heat and blood stasis syndrome should be 1∶1.展开更多

In this study, we developed a novel and simple HPLC-DAD method for simultaneous qualitative and quantitative determination of five major components of Glycyrrhizae Radix et Rhizoma (GRR) in Xiaoer Zhike Tangjiang (...In this study, we developed a novel and simple HPLC-DAD method for simultaneous qualitative and quantitative determination of five major components of Glycyrrhizae Radix et Rhizoma (GRR) in Xiaoer Zhike Tangjiang (XEZKTJ) with standardized reference extract (SRE). The five analytes (liquiritin apioside, liquiritin, isoliquiritin apioside, liquirigenin and glycyrrhizic acid) were well separated with good linearity, precision, stability and repeatability. The recovery rates ranged from 95.69% to 100.80%. The content of the five compounds in 34 batches of commercial XEZKTJ products was determined using standardized GRR extract (SRE method) and individual chemical reference standards (CRS method). Highly similar results were obtained from the two methods, demonstrating the feasibility of the proposed SRE method. Taken together, we proposed an efficient and low-cost way to perform multi-component quality control of XEZKTJ in this study.展开更多

Fifty five samples of Asari Radix et Rhizoma from different sources (35 samples from Asarum heterotropoides var. mandshuricum, 3 samples from Asarum sieboldii var. seoulense, and 17 samples from Asarum sieboldii) were analyzed with this method. Chromatographic separation was achieved on an Agilent Zorbax SB-C18 column (4.6 mm×25 cm, 5 μm) using a gradient elution with mobile phase of aqueous (A) and acetonitrile (B). The assay was carried out at 20 ℃ and with detection at 287 nm. All calibration curves showed good linearity (r2〉0.999) within the tested ranges. The average recoveries were in the range of 96.0%-103.1% with relative standard deviation (RSD) less than 2.54%. The developed method was accurate with high sensitivity and good reproducibility. The content of volatile methyleugenol in LiaoXixin (the root and rhizome ofA. heterotropoides var. mandshuricum and A. sieboldii var. seoulense) was (6.17±5.13) rag/g, which was higher than (0.58±0.40) mg/g in HuaXixin (the root and rhizome ofA. sieboldii). The toxic safrole in LiaoXixin was (2.66±2.16) mg/g, which was lower than (6.44±3.89) mg/g in HuaXixin. This is the first report on the simultaneous and quantitative determination of anthoxylol and sarisan in Asari Radix et Rhizoma.展开更多

However, the drug delivery systems(DDSs) for TCMs remains major challenges due to the characteristics of multi-components including alkaloids, flavones, anthraquinones, glycosides,proteins, volatile oils and other types. Therefore, the novel preparations and technology of modern pharmaceutics is introduced to improve TCM therapeutic effects due to instability and low bioavailability of active ingredients. Salviae Miltiorrhizae Radix et Rhizoma, the radix and rhizomes of Salvia miltiorrhiza Bunge(Danshen in Chinese), is a well known Chinese herbal medicine for protecting the cardiovascular system, with active ingredients mainly including lipophilic tanshinones and hydrophilic salvianolic acids.In this review, this drug is taken as an example to present challenges and strategies in progress of DDSs for TCMs. This review would also summary the characteristics of active ingredients in it including physicochemical properties and pharmacological effects. The purpose of this review is to provide inspirations and ideas for the DDSs designed from TCMs by summarizing the advances on DDSs for both singleand multi-component from Danshen.展开更多

文摘In this study, we developed a novel and simple HPLC-DAD method for simultaneous qualitative and quantitative determination of five major components of Glycyrrhizae Radix et Rhizoma (GRR) in Xiaoer Zhike Tangjiang (XEZKTJ) with standardized reference extract (SRE). The five analytes (liquiritin apioside, liquiritin, isoliquiritin apioside, liquirigenin and glycyrrhizic acid) were well separated with good linearity, precision, stability and repeatability. The recovery rates ranged from 95.69% to 100.80%. The content of the five compounds in 34 batches of commercial XEZKTJ products was determined using standardized GRR extract (SRE method) and individual chemical reference standards (CRS method). Highly similar results were obtained from the two methods, demonstrating the feasibility of the proposed SRE method. Taken together, we proposed an efficient and low-cost way to perform multi-component quality control of XEZKTJ in this study.
文摘Objective To develop a quantitative method for simultaneously determining multi-components in Rhei Radix et Rhizoma using one chemical reference substance.Methods The contents of multi-components were calculated by the UV relative correction factors(RCFs)of chrysophanol,physcion,and rhein to emodin.Results The values of RCFs at 274 nm for rhein,chrysophanol,and physcion to emodin were 0.712,0.674,and 1.051.The calibration curves were linear over the ranges of 0.02-4.08,0.02-4.12,0.07-12.92,and 0.02-3.68μg/mL for rhein,emodin, chrysophanol,and physcion,respectively.The contents of emodin in 18 samples were determined by the external standard method,and the contents of the other three anthraquinone aglycones were calculated according to their RCFs. Conclusion No significant difference is found in comparison with the classical method,indicating that the RCFs have high reliability within their linear ranges and could be used in quality control of Rhei Radix et Rhizoma.The quantitative analysis of multi-component with a single marker is especially suitable for herbal medicines containing unstable or hard to be purified components as quality control markers.

文摘A method using high-performance liquid chromatography for the simultaneous determination of seven principal constituents including xanthoxylol, kakuol, methyleugenol,l-sesamin, safrole, sarisan, and l-asarinin in Asari Radix et Rhizoma (Xixin in Chinese) was developed. Fifty five samples of Asari Radix et Rhizoma from different sources (35 samples from Asarum heterotropoides var. mandshuricum, 3 samples from Asarum sieboldii var. seoulense, and 17 samples from Asarum sieboldii) were analyzed with this method. Chromatographic separation was achieved on an Agilent Zorbax SB-C18 column (4.6 mm×25 cm, 5 μm) using a gradient elution with mobile phase of aqueous (A) and acetonitrile (B). The assay was carried out at 20 ℃ and with detection at 287 nm. All calibration curves showed good linearity (r2〉0.999) within the tested ranges. The average recoveries were in the range of 96.0%-103.1% with relative standard deviation (RSD) less than 2.54%. The developed method was accurate with high sensitivity and good reproducibility. The content of volatile methyleugenol in LiaoXixin (the root and rhizome ofA. heterotropoides var. mandshuricum and A. sieboldii var. seoulense) was (6.17±5.13) rag/g, which was higher than (0.58±0.40) mg/g in HuaXixin (the root and rhizome ofA. sieboldii). The toxic safrole in LiaoXixin was (2.66±2.16) mg/g, which was lower than (6.44±3.89) mg/g in HuaXixin. This is the first report on the simultaneous and quantitative determination of anthoxylol and sarisan in Asari Radix et Rhizoma.

文摘Traditional Chinese medicines(TCMs), with a history of thousands of years, are widely used clinically with effective treatment. However, the drug delivery systems(DDSs) for TCMs remains major challenges due to the characteristics of multi-components including alkaloids, flavones, anthraquinones, glycosides,proteins, volatile oils and other types. Therefore, the novel preparations and technology of modern pharmaceutics is introduced to improve TCM therapeutic effects due to instability and low bioavailability of active ingredients. Salviae Miltiorrhizae Radix et Rhizoma, the radix and rhizomes of Salvia miltiorrhiza Bunge(Danshen in Chinese), is a well known Chinese herbal medicine for protecting the cardiovascular system, with active ingredients mainly including lipophilic tanshinones and hydrophilic salvianolic acids.In this review, this drug is taken as an example to present challenges and strategies in progress of DDSs for TCMs. This review would also summary the characteristics of active ingredients in it including physicochemical properties and pharmacological effects. The purpose of this review is to provide inspirations and ideas for the DDSs designed from TCMs by summarizing the advances on DDSs for both singleand multi-component from Danshen.
