The CH2Cl2 extract from the pericarp of Garcinia hombroniana yielded three 17,14-friedolanostanes [(24E)-3alpha-hydroxy-17,14-friedolanostan-8, 14,24-trien-26-oic acid, methyl (24E)-3alpha,23-dihydroxy-17,14-friedolanostan-8,14,24 -trien-26-oate and methyl (24E)-3alpha,9,23-trihydroxy-17,14-friedolanostan-14,2 4-dien-26-oate] and two lanostanes [3beta- and 3alpha-hydroxy-23-oxo-9,16-lanostadien-26-oic acid]. The structure of (14E)-3alpha-hydroxy-17,14-friedolanostan-8,14,24-trie n-26-oic acid was determined using spectroscopic and X-ray analyses, while the structures of the other compounds were elucidated solely from analysis of spectroscopic data.
山竹子果皮的二氯甲烷提取物产生了三种17,14-降羽扇豆烷类化合物[（24E）-3α-羟基-17,14-降羽扇豆烷-8,14,24-三烯-26-酸、（24E）-3α,23-二羟基-17,14-降羽扇豆烷-8,14,24-三烯-26-酸甲酯和（24E）-3α,9,23-三羟基-17,14-降羽扇豆烷-14,24-二烯-26-酸甲酯]以及两种羊毛脂烷类化合物[3β-和3α-羟基-23-氧代-9,16-羊毛脂二烯-26-酸]。（14E）-3α-羟基-17,14-降羽扇豆烷-8,14,24-三烯-26-酸的结构通过光谱和X射线分析确定，而其他化合物的结构仅通过光谱数据分析阐明。
