Abstract

Corms of Colchicum hierosolymitanum and Colchicum tunicatum were collected, identified and planted under field condition. We report here and for the first time the presence of colchicine in an appreciable amount in both species. The effect of different NPK fertilizer levels on colchicine content of the two Colchicum species at different growth stages were evaluated by HPLC. Results indicated that increasing NPK fertilizer levels significantly improve colchicine content in different plant parts and stages. The highest colchicine content observed in corms was at maturity stage 0.766 mg/g and 0.688 mg/g dry weight with C. hierosolimitanum and C. tunicatum, respectively.

摘要

采集了耶路撒冷秋水仙和有皮秋水仙的球茎，进行鉴定后在田间条件下种植。我们在此首次报告这两个物种中均存在可观含量的秋水仙碱。通过高效液相色谱法（HPLC）评估了不同氮磷钾（NPK）肥料水平对这两种秋水仙在不同生长阶段秋水仙碱含量的影响。结果表明，提高NPK肥料水平可显著提高不同植物部位和阶段的秋水仙碱含量。在球茎中观察到的最高秋水仙碱含量出现在成熟阶段，耶路撒冷秋水仙和有皮秋水仙的干重分别为0.766毫克/克和0.688毫克/克。
