Abstract

Chemical investigation on the flowers of Parthenium hysterophorus has resulted in the isolation of four new pseudoguaianolides, hysterones A-D along with the known compounds, parthenin, coronopilin, 2beta-hydroxycoronopilin and tetraneurin-A. The structures of the new compounds were established by interpretation of their spectral (1D and 2D NMR) data. The X-ray crystallographic analysis of hysterones A and C was also carried out.

摘要

对银胶菊花朵进行化学研究，已分离出四种新的伪愈创木烷型倍半萜内酯，即银胶菊内酯A - D，以及已知化合物银胶菊素、冠冕匹灵、2β - 羟基冠冕匹灵和四烯菌素 - A。通过对其光谱（一维和二维核磁共振）数据的解析确定了新化合物的结构。还对银胶菊内酯A和C进行了X射线晶体学分析。
