Chemical Constituents of Trifolium pratense Seeds

Abstract

A previously undescribed compound 1, along with five known flavonoid derivatives (2－6), a phenylpropane glycoside (7), and two triterpene glycosides (8 and 9), were isolated from the MeOH extract of Trifolium pratense seeds. The structure of 1 was identified based on spectroscopic analysis and alkaline hydrolysis products.
