HPLC/IT-MS Analysis of Glycosides in Radix Polygoni multiflori
摘要
Abstract
HPLC/MS was developed for analysis and identification of glycosides in radix Polygoni multiflori, and the process of ionization of molecular ion of physcion glycoside and quasi-molecular ion of emodin glycoside were studied. Samples were analyzed by a reversed-phase C_(18) column using a binary eluent under gradient conditions,and twelve components were isolated. A collision induced dissociation (CID) experiment was carried out in order to identify the structure of glycosides. The structures of nine glycosides were inferred by MS and information from reports. Three of them: cis-2,3, 5,4'-tetrahydroxystilbene-2-O -β-D-glucopyranoside, torachrysone-8-O-(6'-O-acetyl) -β-D-glucopyranoside, physcion-8-O-(6'-O-acetyl)-B-D-glucopyranoside have not been reported until now.关键词
