Abstract Acid hydrolysis of a crude tomatine preparation from leaves and stems of the wild tomato Lycopersicon pimpinellifolium Mil. yielded, in addition to tomatidine (I), a number of steroidal minor alkaloids. Two of them were shown to be identical with soladulcidine (III) and tomatida-3.5-diene (VI), certainly an artificial product obtained by the acid hydrolysis of naturally occurring tomatid-5-en-3β-ol
摘要 从野生番茄 Lycopersicon pimpinellifolium Mil 的叶和茎中提取的粗
番茄碱制剂的酸
水解。除了
番茄碱 (I) 外,还产生了许多甾体次要
生物碱。其中两个被证明与 soladulcidine (III) 和 tomatida-3.5-diene (VI) 相同,这当然是通过
天然存在的 tomatid-5-en-3β-ol 糖苷酸
水解获得的人工产物。第三种物质,代表一种新的甾体
生物碱,具有经验式 C 27 H 45 NO 3 。最后,一种无
氮化合物也被鉴定为 3β-羟基-5α-pregn-16-en-20-one (VII),它很可能是
番茄碱生物降解的产物。
