摘要

From the methanolic extract of the dried roots of Saussurea lappa Clarke, Saussureae Radix, five amino acid–sesquiterpene conjugates, saussureamines A, B, C, D and E, were isolated together with a lignan glycoside,(−)-massoniresinol 4 ″-O-β-d-glucopyranoside. Their stereostructures were determined on the basis of chemical and physicochemical evidence. In addition, saussureamines and the related amino acid–sesquiterpene ...
