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.
Meehania fargesii (H. LéV.) C. Y. WU 的干燥全株在中国被用作退热剂和解毒剂。从全植物的80%丙酮提取物中获得的水溶性部分显示出抑制透明质酸酶的活性。从这些部分中分离出透明质酸酶抑制剂,以及两种新的精胺生物碱(meefarnines A 和 B)、四种新的 flavone 糖苷(fargenins A—D)和10种已知化合物。通过光谱学方法阐明了每种化合物的结构。
