ethanolic extract of Elephantopus mollis yielded three novel cytotoxic antitumor germacranolides, molephantin, molephantinin, and phantomolin. The extract also yielded three inactive known triterpenes, beta-amyrin acetate, lupeol acetate, and epifriedelanol, as well as stigmasterol. The structure and stereochemistry of the cytotoxic antitumor agents molephantin, molephantinin, and phantomolin were determined
软体象的乙醇提取物产生了三种新型的细胞毒性抗肿瘤生殖器ran兰,莫芬汀,莫芬汀和幽灵素。提取物还产生了三种已知的非活性三萜类化合物,醋酸β-胰淀粉糊精,醋酸羽扇豆酚和表氟甘油,以及豆甾醇。基于化学转化和光谱证据确定了细胞毒性抗肿瘤药莫尔芬汀,莫尔芬汀和幽灵霉素的结构和立体化学。初步的体内肿瘤试验表明,莫芬汀和酚酞是Ehrlich腹水癌和Walker 256癌肉瘤的有效抑制剂。在P-388淋巴细胞性白血病筛查中,番茄红素还显示出显着的抗白血病活性。
