Abstract

Alkaloid pattern of individuals from 16 Bulgarian Galanthus elwesii populations was investigated by GC/MS and TLC. Twenty-one Amaryllidaceae alkaloids were detected and 14 of them were identified. Crinane type alkaloids, haemanthamine or crinine, dominated alkaloid metabolism in most of the populations. With exception of one population, where the separate individuals showed variable alkaloid profiles (dominated by crinine or haemanthamine) the individuals of the rest of populations have identical and characteristic alkaloid profiles. Some populations showed remarkable differences in respect to their alkaloid pattern-type of biosynthesis, main alkaloids and number of alkaloids. Populations dominated by galanthamine type alkaloids were found as well. These data demonstrate that like the morphological features, the alkaloid metabolism of G. elwesii is also variable.

摘要

通过气相色谱/质谱联用仪（GC/MS）和薄层色谱法（TLC）对来自16个保加利亚雪滴花种群的个体的生物碱模式进行了研究。检测到21种石蒜科生物碱，其中14种已被鉴定。在大多数种群中，水仙环素型生物碱，海芒果碱或水仙碱，主导着生物碱代谢。除了一个种群外，该种群中单独的个体显示出可变的生物碱谱（以水仙碱或海芒果碱为主），其余种群的个体具有相同且特征性的生物碱谱。一些种群在生物碱模式 - 生物合成类型、主要生物碱和生物碱数量方面表现出显著差异。也发现了以加兰他敏型生物碱为主的种群。这些数据表明，与形态特征一样，雪滴花的生物碱代谢也是可变的。
