Arjunolic acid, an oleanene-type triterpene isolated from the rhizome of Cochlospermum tinctorium, its triacetate derivative, and their methyl esters were tested using the short-term in vitro assay on EBV-EA activation in Raji cells induced by 12-O-tetradecanoyl-phorbol-13-acetate (TPA). Their inhibitory effects on skin tumor promotors were found to be greater than those of previously studied natural products.
从黄栌根茎中分离得到的齐墩果烷型三萜阿朱诺酸、其三乙酸酯衍生物及其甲酯，采用短期体外试验，检测它们对12-O-十四烷酰佛波醇-13-乙酸酯（TPA）诱导的Raji细胞中EBV-EA激活的作用。发现它们对皮肤肿瘤促进剂的抑制作用比先前研究的天然产物更强。
