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.
