Abstract
A mutagenic principle in the water extract from Catalpae Fructus (originated from Catalpa ovata G. DON) (Bignoniaceae) was isolated and characterized as a new iridoid named catalpin. The iridoid exhibited mutagenic activity towards Salmonella typhimurium strain TA100 in the presence and absence of rat liver homogenate (S9) mix in Ames' test.
摘要
从梓树（紫葳科，原产于梓树）果实的水提取物中分离出一种诱变成分，并鉴定为一种名为梓苷的新环烯醚萜。在艾姆斯试验中，无论有无大鼠肝脏匀浆（S9）混合物存在，该环烯醚萜对鼠伤寒沙门氏菌TA100菌株均表现出诱变活性。
