The purgative principles in Croton penduliflorus seed oil were isolated as white crystals by a bioassay-guided chromatographic separation process. The crystals were recovered in 7% w/w yield and identified (IR, 1H-NMR, GC-MS) as a mixture of palmitic, stearic and arachidic acids in approximately equimolar concentration.
通过生物活性导向的色谱分离法，从巴豆种子油中分离出具有泻下作用的成分，得到白色晶体。晶体的得率为7%（重量/重量），经鉴定（红外光谱、氢核磁共振谱、气相色谱-质谱联用）为棕榈酸、硬脂酸和花生酸的混合物，其浓度大致相等。
