发现大戟胶乳的极性较低的级分在游离和酯化的三萜醇级分中含有钝叶醇、环阿屯醇、24-亚甲基环木菠萝烷醇、羊毛甾醇和24-亚甲基羊毛甾醇; 9-顺式-三萜醇作为烃级分的主要组分;以及一种新的无环三萜醇，命名为peplusol（1）。通过光谱和化学方法确定化合物1的结构为（全反式）-2（5，9-二甲基-1-亚甲基-4，8-癸二烯基）-5，9，13-三甲基-4，8，12-十四碳三烯-1-醇的R-异构体。
The less polar fractions of the latex of Euphorbia peplus were found to contain obtusifoliol, cycloartenol, 24-methylenecycloartanol, lanosterol, and 24-methylenelanosterol in the free and esterified triterpene alcohol fractions; 9-cis-tricosene as the major component of the hydrocarbon fraction; and a new acyclic triterpene alcohol named peplusol (1). The structure of 1 was determined as the R-isomer of (all-E)-2(5,9-dimethyl-l-methylene-4,8-decadienyl)-5,9,13-trimethyl-4,8,12-tetradecatrien-1-ol by spectral and chemical methods.
