豺皮樟和圆叶豺皮樟中的阿朴啡生物碱成分

APORPHINE ALKALOIDS OF LITSEA ROTUNDIFOLIA AND L. ROTUNDIFOLIA VAR. OBLONGIFOLIA

摘要:

从豺皮樟(Litsea rotundifolia var.0bfongifolia)和圆叶豺皮樟(Litsea rotundifolia)的茎中分离得到三个阿朴啡型生物碱成分,通过光谱解析及化学方法,三个化合物分别鉴定为降波尔定(1)、波尔定(2)和氮乙酰降波尔定(3)。其中氮乙酰降波尔定系首次直接从植物中得到。

Abstract:

Three aporphine alkaloids, laurolitsine, boldine and N-acetyllaurolitsine were isolated from the stems of both Litsea rotundifolia and L. rotundifolia var. oblongifolia. Their structures were identified on the basis of spectral analysis and chemical correlation. Among them, N-acetyllaurolitsine was found as a naturally occurring compound for the first time.

Key words:Litsea rotundifolia; Litsea rotundifolia var. Oblongifolia; Aporphine alkaloids; N-acetyllaurolitsine
