摘 要 ：从大理翠雀Delphynium taliense Franch 根中分得五个二萜生物碱，其中四个已有报告，分别鉴定为methyllycaconitine，delsemine、大理翠雀碱乙(talitine B)、大理翠雀碱丙(talitine C) 。本文主要通过质谱、红外光谱、核磁共振氢谱及其碳谱对大理翠雀碱甲的化学结构所进行的推导。
Abstract:A new diterpenoid alkaloid, talitine A, isolated from Delphynium taliense Franch, together with four alkaloids reported previously, was deduce as (1 ) on the basis of spectral studies and its relation with talitine B.
