Cyclic Spermidine Alkaloids and Flavone Glycosides from Meehania fargesii

Abstract

The dried whole plant of Meehania fargesii (H. LéV.) C. Y. WU is utilized as an antipyretic and antidote for poison in China. Water soluble fractions, obtained from an 80% acetone extract of the whole plant, showed hyaluronidase inhibitory activity. From these fractions, hyaluronidase inhibitors were isolated along with two new spermidine alkaloids (meefarnines A and B), four new flavone glycosides (fargenins A—D), and 10 known compounds. The structure of each was elucidated by spectroscopic methods.
