Ferula spp. are traditional medicinal plants found in arid land. Large-scale excavation for extracting bioactive compounds from the plants in arid regions of Xinjiang over the last few years has, however, significandy decreased their distributions. Due to the urgent need for preservation of these plant resources, along with the need of searching for alternative source of the useful metabolites, it is important to screen the endophytic microbial resources associated with the plant Ferula sinkiangensis K. M. Shen. In the study, a total of 125 endophytic bacteria belonging to 3 phyla, 13 orders, 23 families, and 29 genera were isolated based on 16S rRNA gene sequencing data. Among the different isolates, three strains isolated from roots were potential novel species of the genera Porphyrobacter, Paracoccus and draycofatopsis. In this study, 79.4% and 57.1% of the total isolates were capable of producing indole-3-acetic acid (IAA) and siderophore, respectively. And, 40.6% of the strains inhibit the growth of fungal pathogen Afternaria alternata, 17.2% and 20.2% strains were positive for antagonism against Vertidllium dahlia 991 and V. dahlia 7, respectively. These results demonstrated that E sinkiangensis is a rich reservoir of endophytic bacterial resources with potential for production of biologically important functions such as plant growth-promoting factors. 展开更多

OBJECTIVE Learning and memory impairment is one of the common sequelae of stroke patients,which is called"post-stroke dementia"and seriously affects the quality of life of the patients.For post-stroke dementia,there is still no effective clinical treatment.In the present study,we aim to investigate the effect of the active ingredient of Ferula sinkiangensis,AW09,on global cerebral ischemia-reperfusion mice.METHODS The bilateral common carotid artery occlusion(BCCAO)reperfusion model was used to investigate the protective effect of AW09 on cognitive dysfunction in mice with global cerebral ischemia reperfusion.Y-maze and Morris water maze were used to test the learning and memory ability of mice.RESULTS Y-maze test showed that AW09 treatment significantly increased the spontaneous alternation rate of BCCAO model animals and had no significant effect on the total number of arm entries.The results of Morris water maze showed that AW09 significantly reduced the escape latency of BCCAO mice during the training period.During the probe test phase,AW09 significantly increased the swimming time in target quadrant,distance in target quadrant and number of platform crossings and decreased the swimming time in the quadrant opposite the target quadrant of BCCAO mice.CONCLUSION AW09,the active ingredient of Ferula sinkiangensis,can improve working memory impairment and spatial memory impairment in animals with global cerebral ischemia-reperfusion,suggesting that AW09 has poten⁃tial therapeutic value for cognitive dysfunction caused by global cerebral ischemia. 展开更多

The resin of Ferula sinkiangensis has been traditionally utilized for treating gastrointestinal disorders,inflammation,tumors,various cancers,and alopecia areata.The primary bioactive constituents,sesquiterpene coumarins,have demonstrated notable therapeutic potential against neuroinflammation.In this study,a structure-guided fractionation method was used to isolate nine novel sesquiterpene coumarins from the resin of F.sinkiangensis.These compounds were characterized and structurally elucidated using comprehensive physicochemical and spectroscopic techniques,including calculated electronic circular dichroism(ECD).Anti-neuroinflammatory assays revealed that compounds 2,3,and 6 significantly inhibited nitric oxide(NO)production in lipopolysaccharide(LPS)-stimulated BV2 microglial cells,with IC_(50)values ranging from 1.63 to 12.25μmol·L^(−1). 展开更多
