| 3 | Quality Standard for Euonymi Grandiflorus Caulis and Folium显示文摘[Objectives]To establish the quality standard for Euonymi Grandiflorus Caulis and Folium.[Methods]Qualitative identification was performed by methods of origin identification,microscopic identification and thin layer chromatography(TLC);the moisture,total ash,acid-insoluble ash,and extract were detected using the method in the Chinese Pharmacopoeia(2020 Edition),and the contents of quercetin and kaempferol were determined by High Performance Liquid Chromatography(HPLC).[Results]The leaves of Euonymi Grandiflorus were subleathery,narrow and long elliptic or narrow obovate with cyme,and capsules were often with narrow wing ridge.Characteristics of microscopic identification were significant.Calcium oxalate cluster crystals,cubic crystals,inlaid parenchyma cells,starch granules,stomata,and fiber bundles could be observed.A TLC method for identification of Euonymi Grandiflorus Caulis and Folium was established.The contents of water,total ash,acid-insoluble ash were not higher than 13%,9%,12%,respectively;the extract were no less were not higher than 13%,9%,12%and 17%in ten batches of samples,respectively;the sum of quercetin and kaempferol were no less than 0.20%.[Conclusions]The quality standard of Euonymi Grandiflorus Caulis and Folium were established through the research.This method is accurate,specific,and reproducible and can be used for the quality control of Euonymi Grandiflorus Caulis and Folium. | Qi CUI Yuanlin KONG Mingkang FENG Riluo FENG Luha AYI Ying LI Chen CHEN Wenbing LI Yuan LIU | 2022 | Medicinal Plant2022，13，4： | 0 |
| 4 | Assessment of residual chlorine in soil microbial community using metagenomics显示文摘Chlorine-containing disinfectants have been widely used around the world for the prevention and control of the COVID-19 pandemic.However,at present,little is known about the impact of residual chlorine on the soil micro-ecological environment.Herein,we treated an experimental soil-plant-microbiome microcosm system by continuous irrigation with a low concentration of chlorine-containing water,and then analyzed the influence on the soil microbial community using metagenomics.After 14-d continuous chlorine treatment,there were no significant lasting effect on soil microbial community diversity and composition either in the rhizosphere or in bulk soil.Although metabolic functions of the rhizosphere microbial community were affected slightly by continuous chlorine treatment,it recovered to the original status.The abundance of several resistance genes changed by 7 d and recovered by 14 d.According to our results,the chlorine residue resulting from daily disinfection may present a slight long-term effect on plant growth(shoot length and fresh weight)and soil micro-ecology.In general,our study assisted with environmental risk assessments relating to the application of chlorine-containing disinfectants and minimization of risks to the environment during disease control,such as COVID-19. | Yitian Yu Qi Zhang Zhenyan Zhang Nuohan Xu Yan Li Mingkang Jin Guoqiang Feng Haifeng Qian Tao Lu | 2023 | Soil Ecology Letters2023，5，1： | 0 |
| 5 | Quality Standard of Qiang Herb Sophora davidii var.chuansiensis显示文摘[Objectives]To establish the quality standard of common clinical folk herb Sophora davidii var.chuansiensis.[Methods]The qualitative identification was performed by microscopic method and thin-layer chromatography(TLC).The contents of moisture,total ash,acid insoluble ash and extract were determined according to the methods of the Chinese Pharmacopoeia(2020).High performance liquid chromatography(HPLC)was used to determine the contents of oxymatrine and oxysophocarpine.[Results]The microscopic characteristics were obvious,including crystal sheath fiber,calcium oxalate square crystal,non glandular hair,stone cells,epidermal cells,stomata,cork cells,vessels with marginal pits and so on.TLC spots were clear,and the resolution was good.The contents of moisture,total ash,acid insoluble ash and extract from 10 batches of samples were 4.70%-8.33%,3.43%-4.19%,0.65%-1.02%and 14.67%-22.04%respectively.The determination results of oxymatrine were between 0.10%-0.33%,with an average value of 0.19%.The determination results of sophocarpine oxide were between 0.30%-0.38%,with an average value of 0.34%.[Conclusions]The established quality standard of S.davidii var.chuansiensis had good specificity and accuracy,and could be used for the quality control of herb S.davidii var.chuansiensis. | Mingkang FENG Qubiejunzhang Qubieaxiang Dongmei SHA Wenbing LI Yuan LIU | 2023 | Medicinal Plant2023，14，1： | 0 |
