从辛夷（Ｍａｇｎｏｌｉａｂｉｏｎｄｉｉｐａｍｐ．）水溶性部位分离得到三个化合物，木兰碱（Ⅰ），Ｅ－对羟基桂皮酸乙酯（Ⅱ）及一个新化合物（Ⅲ），利用光谱法确定其结构为山萘素－７－Ｏ－β－（６″－对羟基桂皮酰）－Ｄ－葡萄糖甙。命名望春花黄酮醇甙Ⅰ（ｂｉｏｎｄｎｏｉｄⅠ，Ⅲ）。
Three compounds were isolated from the water-soluble part of Magnolia biondiipamp. Magnolia base (I), E-p-hydroxycinnamic acid ethyl ester (II) and a new compound (III) were determined by spectroscopic analysis to be kaempferol. -7-O-β-(6"-p-hydroxycinnamoyl)-D-glucoside. Named biondnoid I, III.
