摘　　要：从番荔枝科哥纳香属植物大花哥纳香（Ｇｏｎｉｏｔｈａｌａｍｕｓｇｒｉｆｆｉｔｈｉ）的叶中分离到４个化合物，ｇｒｉｆｉｔｈｉｎｅＡ（Ｉ），ｇｏｎｉｏｄｉｏｌｍｏｎｏａｃｅｔａｔａ（Ⅱ），β－ｓｉｔｏｓｔｅｒｏｌ（Ⅲ）和β－ｄａｕｃｏｓｔｅｒｏｌ（Ⅳ）。其中（Ｉ）为新化合物。Four compounds were isolated from laves of Goniothalamus griffithii. Their structures were determined by means of spectral method. Three of them were identified as goniodiol monoacetate (Ⅱ),β-sitosterol (Ⅲ) and β-daucosterol (Ⅳ). One of them was new,whose structure was elucidated as cycloat-23-ene-16β,25-diol named as griffithine A (I).
