  • Title: [Structure of swertiamacroside from Swertia macrosperma C.B. Clark].
    Author: Zhou HM, Liu YL.
    Journal: Yao Xue Xue Bao; 1990; 25(2):123-6. PubMed ID: 2239318.
    Abstract:
    From the air-dried whole plant of SwerBia macrosperma C. B. Clark four compounds I-IV were isolated. One of them is a new caffeic acid disaccharide ester. Its structure was elucidated as 1-O-trans-caffeoyl-6-O-alpha-L-rhamnopyranosyl-beta-D-glucopyranos ide, i. e. trans caffeic acid-1-O-rutinose ester on the basis of chemical and spectroscopic analysis, and named swertiamacroside (I). The other three known compounds were identified as mangiferin (II), bellidifodin (III) and bellidifodin-8-O-beta-D-glucopyranoside (IV).
