Abstract

Red squill bulbs, with reported specific rodenticidal properties, have been assayed for their content of the two main glycosides, scilliroside and scillaren A, by a method depending on the separation of the glycosides from purified plant extracts by tlc followed by spectrophotometric (uv and visible) determination of the individual glycosides in the eluates. The method was found convenient for assessment of the potency of red squill bulbs.

摘要

红海葱鳞茎据报道具有特定的灭鼠特性，已通过一种方法对其两种主要糖苷——红海葱苷和海葱苷A的含量进行了测定。该方法是先通过薄层色谱法将糖苷从纯化的植物提取物中分离出来，然后用分光光度法（紫外和可见光）测定洗脱液中各糖苷的含量。结果发现该方法便于评估红海葱鳞茎的效力。
