- W2353870070 abstract "Objective To compare the content of nitidine chloride in different plant parts of Zanthoxylum nitidum(Roxb.)DC.from Guangdong and Guangxi provinces.Methods With 70% methanol as the extraction solvent,ultrasonic method was used for the extraction of nitidine chloride.The content of nitidine chloride was determined by high performance liquid chromatography(HPLC),and the chromatographic conditions were as follows:gradient elution,Hypersil ODS C18 column(4.6 mm×200 mm,5 μm),and the mobile phase consisting of acetonitrile(A)and 1.22 g/L formic acid-triethylamine(pH=4.5)(B).Results The average recovery of nitidine chloride was 98.32% with RSD being 1.85%.Roots of Zanthoxylum nitidum from Guangdong and Guangxi provinces had the highest content of nitidine chloride.Stems of Zanthoxylum nitidum from Guangxi had a higher content of nitidine chloride than that in the stems from Guangdong.Nitidine chloride was not found in the leaves of Zanthoxylum nitidum from Guangdong and Guangxi.Conclusion Nitidine chloride content varies in different parts of Zanthoxylum nitidum from different producing places.The established method is simple,rapid and accurate,which can supply reference for the selection of medicinal parts and development of sources of Zanthoxylum nitidum(Roxb.)DC." @default.
