The chemical constituents of Desmodium sambuense were studied. Chromatographic techniques were applied to isolate and purify the constituents, and the structures were identified on the basis of physico-chemical and spectroscopeic methods. Thirteen compounds were isolated from the 75% ethanol extract of Desmodium sambuens and elucidated as beta-amyrin(1), betulic acid(2), daucosterol(3), triacontanoic acid(4), lup-20(29)-en-3-one(5), tetracosanoic-2,3-dihydroxypropylester(6), stigmast-5-ene-3beta, 7alpha-ol (7),methyl phaeophorbidea(8), o-hydroxy benzoic acid(9),beta-sitosterol(10),d-catechin(11), luteolin (12), epigallocatechin (13). All of the compounds were isolated from this plant for the first time.
对山黑豆的化学成分进行了研究。采用色谱技术分离和纯化其成分，并根据物理化学和光谱方法鉴定其结构。从山黑豆75%乙醇提取物中分离出13种化合物，分别鉴定为β-香树脂醇（1）、桦木酸（2）、胡萝卜苷（3）、三十烷酸（4）、羽扇-20（29）-烯-3-酮（5）、二十四烷酸-2,3-二羟基丙酯（6）、豆甾-5-烯-3β,7α-二醇（7）、脱镁叶绿酸甲酯（8）、邻羟基苯甲酸（9）、β-谷甾醇（10）、d-儿茶素（11）、木犀草素（12）、表没食子儿茶素（13）。所有化合物均首次从该植物中分离得到。
