Abstract
Objective To study the constituents of Discocleidion rufescens. Methods The constituents were separated by column chromatography and their structures were elucidated by spectroscophic means. Results Six constituents were identified to be ellagic acid (Ⅰ),3,3',4'-trimethyl ellagic acid (Ⅱ),3,3'-di-O-methyl ellagic acid (Ⅲ),3,3',4-tri-O-methyl ellagic acid-4'-O-β-D-glucopyranoside (Ⅳ),3,3'-di-O-methylellagic acid-4'-O-β-D-glucopyranoside (Ⅴ),3,3'-di-O-methylellagic acid-4'-O-β-D-xylopyranoside (Ⅵ),and others are ricinine (Ⅶ),umbelliferon (Ⅷ),scopolin (Ⅸ),p-coumaric acid (Ⅹ),ferulic acid (Ⅺ),and vanillic acid (ⅩⅡ). Conclusion Constituents Ⅰ-ⅩⅡ are obtained from the plants of Discocleidion (Muell.-Arg.) Pax et Hoffm for the first time.
