Abstract Heliosupine, heliosupine N-oxide, 3′-acetylheliosupine, and viridiflorine were isolated and identified on the base of MS, 1 H and 13 C NMR from Cynoglossum officinale . Altogether 14 pyrrolizidine alkaloids were separated and identified by GLC and GLC-MS in the alkaloid extracts from different parts of Cynoglossum officinale . From Cynoglossum amabile five pyrrolizidine alkaloids were recorded: supinine, amabiline, rinderine, echinatine, and 3′- O -acetylechinatine.

Cynoglossum officinale 和 Cynoglossum amabile（紫草科）的吡咯里西啶生物碱

摘要 通过MS、 1 H 和 13 C NMR 从药用草中分离并鉴定了天竺葵素、天竺葵素N-氧化物、3'-乙酰天竺葵素和绿花素。通过GLC和GLC-MS共分离鉴定了药用不同部位生物碱提取物中的14种吡咯里西啶类生物碱。从 Cynoglossum amabile 中记录了五种吡咯里西啶生物碱：supinine、amabiline、rinderine、echinatine 和 3'-O-acetylechinatine。
