近年来从植物和菌类中陆续分离得一些去甲二萜内酯成份。在研究高等植物的肿瘤抑制化合物的过程中,作者从红豆杉科 Podocarpus Pilg所分离得的新成分 podolide(Ⅰ)是这类化合物中第一个具有肿瘤抑制活性化合物。该植物细枝和叶乙醇提取物所得的肿瘤抑制活性成分,在进行氯仿-水的分配时,使集中于氯仿层中,然后在含水甲醇-Skellysolve B 分配时,又使集 In recent years, plants and fungi have been isolated from some of the nordeldanterolactone ingredients. The podolide (Ⅰ), the new component isolated from the author Podocarpus Pilg in the study of tumor suppressor compounds in higher plants, is the first of its kind to have a tumor suppressor activity. The tumor-inhibitory active ingredients obtained from the plant twigs and the leaf alcohol extracts were concentrated in a chloroform layer during the distribution of the chloroform-water, and then, while being partitioned by the hydrous methanol-Skelysosolve B,
