从浙江天目山采集的森林千里光(Senecio nemorensis)中分得二个双稠吡咯啶类型的生物碱,其中之一熔点为55—57℃,分子式为C_(13)H_(21)O_3N。另一熔点为42—43℃,分子式为C_(18)H_(27)O_5N。由其理化常数及酒石酸盐、苦味酸盐、水解产物等结果,与文献上记载的大叶千里光中所得的macrophylline及从瓶草千里光中所得的sarracine比较,证明前者与macrophylline相同,而后者与sarracine相同。
Two bipyrylpyrrolidine-type alkaloids were isolated from Senecio nemorensis collected from the Tianmu Mountain in Zhejiang Province, one of which had a melting point of 55-57°C and a molecular formula of C_(13)H_(21)O_3N. The other melting point is 42-43°C and the molecular formula is C 18 H 27 O 5N. The physicochemical constants and the results of tartrates, picrates, and hydrolysates are compared with the macrophylline obtained in the literature and the sarracine obtained from the Schizophyllum punctatus. It is proved that the former is the same as the macrophylline, and the latter Same as sarracine.
