| 1 | Study on Quality Standard of Hibiscus trionum L.显示文摘[Objectives]To establish the quality standard for Hibiscus trionum L.[Methods]The moisture,total ash,acid insoluble ash and extract of H.trionum L.were determined by the method of Chinese Pharmacopoeia 2020 edition.The medicinal materials were qualitatively identified by microscopic identification and TLC,and the content of quercetin was determined by HPLC.[Results]The moisture,total ash,acid insoluble ash and extract contents of the 12 batches of samples were 7.69%-12.94%,10.44%-14.62%,1.89%-3.64%,16.56%-21.81%,microscopic characteristic was obvious,and a method for TLC and content determination of H.trionum L.was established.[Conclusions]A perfect quality standard was established,which can be used for the quality control of H.trionum L. | Quan MA Yang WEN Yuebu HAILAI Yuan LIU Junyin LU Tao WANG Wenbing LI | 2023 | Medicinal Plant2023，14，3： | 0 |
| 2 | Quality Standard of Oxyria sinensis Hemsl显示文摘[Objectives]To establish the quality standard of Oxyria sinensis Hemsl.[Methods]The method in Chinese Pharmacopoeia(2020 edition)was used to determine the moisture,total ash,acid-insoluble ash and alcohol-soluble extracts of O.sinensis.The qualitative identification of medicinal materials was carried out by microscopic identification method and thin layer chromatography(TLC).The contents of hyperoside and isoquercitrin were determined by high performance liquid chromatography(HPLC).[Results]The total amount of moisture,total ash,acid-insoluble ash,alcohol-soluble extract,hyperoside and isoquercitrin of 12 batches of medicinal materials were 8.56%-11.53%,11.26%-15.48%,1.62%-2.56%,17.75%-26.09%,and 0.036%-0.42%,respectively.The microscopic features were obvious,and pores,fibers,calcium oxalate clusters,calcium oxalate square crystals,cork cells could be observed.Fluorescent spots of the same color were displayed at the positions corresponding to the hyperoside reference substance.[Conclusions]Establishing relatively complete quality standards for O.sinensis medicinal materials can provide a reference for the quality control of medicinal materials. | Yang WEN Yuebu HAILAI Quan MA Yuan LIU Junyin LU Wenbing LI | 2023 | Medicinal Plant2023，14，3： | 0 |
| 3 | Determination and Multidimensional Analysis of 29 Inorganic Elements in Cardamine tangutorum O.E.Schulz of Different Origins显示文摘[Objectives]This study aimed to determine the contents of inorganic elements in Cardamine tangutorum O.E.Schulz samples from different origins to provide a scientific reference for the quality control,safety evaluation and clinical medicinal use of C.tangutorum O.E.Schulz.[Methods]The contents of Al,As,B,Ba,Ca,Cd,Co,Cr,Cu,Fe,Hg,K,Mg,Mn,Mo,Na,Ni,P,Pb,Pd,Rb,Se,Si,Sn,Sr,Ti,Tl,V and Zn in the C.tangutorum O.E.Schulz samples were determined simultaneously by wet digestion and inductively coupled plasma optical emission spectroscopy(ICP-OES),and the determination results were analyzed by principal component analysis.[Results]A total of 28 inorganic elements were detected in the samples of C.tangutorum O.E.Schulz from different origins.The contents of heavy metals did not exceed the limits.Among the elements,the determined values of Hg in all samples were below the detection limit,so it was not detected.The contents of Ca,Al,P and Fe were relatively high,and they were essential nutrients in the human body.There were significant differences among different elements.Samples from different origins show similar patterns in the distribution of main elements.Correlation analysis shows that 15 pairs of inorganic elements out of 24 elements had extremely significant positive correlations,and 26 pairs of elements had significant positive correlations.The principal component analysis determined Al,As,Ba,Ca,Cd,Fe,Mn,Ni,P,Pb,Pd,Se,V and Zn were the characteristic inorganic elements in the samples of C.tangutorum O.E.Schulz.[Conclusions]The contents of toxic heavy metals in C.tangutorum O.E.Schulz samples from different origins met the edible requirements.The method was simple,rapid and accurate,and could be used to analyze and determine the inorganic elements in the samples of C.tangutorum O.E.Schulz,providing a theoretical basis for the better development and utilization of C.tangutorum O.E.Schulz. | Xiaoxia CAI Bochao LI Junzhang QUBIE Yuebu HAILAI Jianlong LAN Wenbing LI Yuan LIU | 2020 | Medicinal Plant2020，11，6： | 0 |
| 4 | Quality Standard of Yi Medicinal Material Anaphalis margaritacea显示文摘[Objectives]To establish quality standards for traditional Yi medicine of the Anaphalis margaritacea.[Methods]The original plants,traits,identification and TLC was used to identify L.franchetii Beauv.water content,total ash,acid-insoluble ash and extract were checked according to the Chinese Pharmacopoeia(2020 Edition).The content of 3,5-dicaffeoylquinic acid was determined by HPLC.[Results]The microscopic identification features are obvious,epidermal cells,stomata,non-glandular hairs,annular vessel,conduit wood fiber,pollen grains,starch grains,calcium oxalate clusters were observed,etc.TLC showed clear spots and good resolution.The extract content of acid-insoluble ash aqueous solution in 16 batches of samples was 5.22%-9.33%,6.79%-14.47%,0.39%-3.30%,20.49%-32.93%,respectively.3,5-O-dicafeylquinic acid showed good linear relationships within their own ranges(R^(2)=1.0),whose average recoveries were 99.11%with the RSD of 1.35%,respectively.[Conclusions]The method adopted was reasonable and feasible,and could be used for quality control of A.margaritacea. | Ciga DIJIU Jianlong LAN Yuebu HAILAI Zhengming YANG Yuan LIU | 2022 | Medicinal Plant2022，13，5： | 0 |
| 5 | Quality Standard of Zijinbiao显示文摘[Objectives]To establish the quality standard for Zijinbiao.[Methods]Microscopic identification,physical and chemical identification,and thin-layer chromatography(TLC)were used to qualitatively identify Zijinbiao.The moisture,total ash,acid-insoluble ash,and alcohol-soluble extract content were determined.The content of Plumbagin was determined by high performance liquid chromatography(HPLC).[Results]Microscopic identification,physical and chemical identification and thin layer identification features were remarkable.The moisture,total ash,acid-insoluble ash,and extract content of the 15 batches of samples were 7.49%-11.84%,2.43%-5.81%,0.59%-3.18%and 13.80%-20.45%,respectively.The linear equation of Plumbagin was Y=38094X,R^(2)=0.9996.Plumbagin had a good linear relationship in the range of 0.01-0.53 mg/mL.[Conclusions]This method is specific and reproducible,and can be used for quality control of Zijinbiao. | Jianlong LAN Yuebu HAILAI Cijia DIJIU Hongna SU Li LI Zhengming YANG Yuan LIU | 2022 | Medicinal Plant2022，13，5： | 0 |
