Bioassay of different extract of clerodendruminfortunatum on some vegetables seeds with their chemical investigation

Abstract

An experiment was conducted on bioassay of different extracts of Clerodendrum infortunatum leaves for each vegetable crop such as, swamp cabbage, ladies finger, and yard long bean with the attempt for chemical investigation on effective plant extract. The chloroform extract of Clerodendrum infortunatum has significantly increased and enhanced the germination, growth of shoot length and root length of yard long bean and swamp cabbage whereas, reduced and delayed the germination, growth of shoot length and root length of lady’s finger seeds compared with control. The study revealed that different extract of Clerodendrum infortunatum contains growth regulatory active compounds. Among the extracts, chloroform extracts showed better performances in terms of percent germination and growth of shoot and root length of yard long bean and swamp cabbage. To find out effective compound from chloroform extracts, thin layer chromatography was done which showed five distinct compounds. These compounds were separated by preparative Thin Layer Chromatography. Further study is needed to determine structure for finding growth regulatory compound in Agricultural usage.
