Abstract

The potential of an allelopathic plant to exert direct and indirect effects depends in large part on the chemistry of the plant and whether putative allelochemicals reach meaningful levels in the environment surrounding the plant. Cleome viscosa L. (Capparidaceae) (synonym: C. icosandra L.) is a weed distributedthroughout the tropics of the world and the plains of India Results on the qualitative analysis on the root, stem and leaves of C. viscosa showed that the presence of saponins and flavonoids in all their three organs. The presence of alkaloids was noticed only in Wagner's test not in the Mayor's and Dragendorff's test. GC-MSresults of whole plant of C.viscosa showed the presence 3-O-Methyl-d-glucose (73%), followed by Benzofuran,2,3-dihydro (9.844%) and : n-Hexadecanoic acid (4.707%) of the total 32 compounds.

Highlights

Allelochemicals are the small molecular weight compounds excreted from plants during the process of secondary metabolism (Rice, 1984)

Summary

INTRODUCTION

Allelochemicals are the small molecular weight compounds excreted from plants during the process of secondary metabolism (Rice, 1984). These chemicals usually accumulated in plants, soils, and other surrounding organisms. Phenolic acids are noted for their direct toxicity to some organisms (Chon and Kim, 2002) and are capable of interacting with nutrients in soils (Blum et al, 1993), altering their availability to target organisms The importance of such indirect effects probably varies across environmental gradients in the field. The present work has been aimed to investigate the phytochemical analysis of Tick weed (Cleome viscosa L.) using GC-MS techniques
