Abstract

The galanthamine, lycorine, and lycoramine content of Lycoris chinensis was researched during development from young to old plants, i.e. in seeds, ten-day-old seedlings, three-month-old seedlings, one-year-old seedlings, and perennial seedlings. Notably the alkaloid level reduced to its lowest content 10 days after seed germinating. Then the accumulation of galanthamine tended to increase with age, reaching a higher value in perennial seedlings. The production pattern of lycorine and lycoramine was found similar to that of galanthamine. Different plant organs were also evaluated for their galanthamine, lycorine, and lycoramine contents. Mature seeds had the highest content of galanthamine (671.33 microg/g DW). Kernels, seed capsules, and root-hairs were the main repository sites for galanthamine, lycorine, and lycoramine. The leaves were the least productive organs.

摘要

对石蒜从幼龄到老龄植株（包括种子、10 日龄幼苗、3 月龄幼苗、1 年生幼苗和多年生幼苗）的生长发育过程中的石蒜碱、石蒜伦碱和石蒜胺含量进行了研究。值得注意的是，种子发芽后 10 天，生物碱含量降至最低。然后，加兰他敏的积累随着年龄的增长而增加，在多年生幼苗中达到较高值。发现石蒜伦碱和石蒜胺的产生模式与加兰他敏相似。还评估了不同的植物器官的加兰他敏、石蒜伦碱和石蒜胺含量。成熟种子的加兰他敏含量最高（671.33μg/g DW）。种皮、种子胶囊和根毛是加兰他敏、石蒜伦碱和石蒜胺的主要储存部位。叶片是产量最低的器官。
