Abstract

Plan: The present study was undertaken to identifythe possible bioactive components andantimicrobial activity in variouspolar solvents from the leaves of Anjan grass (Cenchrus ciliaris) (Poaceae).

Materials and methods: New compounds were identified by GC-MS analysis. Antimicrobial activitywas evaluated against Proteus mirabilis,Klebsiella pneumoniae, Agrobacterium tumefaciens and Aspergillus niger using diskdiffusion method followed by MIC by broth dilution method.

Outcome:Various aromatic, steroids, fatty acids andesters from C. ciliariswere identified. The prevailing compounds in the ethyl acetate extract of C. ciliaris were 4,22-stigmastadiene-3-one (2.41%),cyclopentacycloheptene(azulene) (1.81%), ergost-5-en-3-ol (3β, 24R)- (campesterol)(1.63%) and myristic acid, isopropyl ester(0.17%). The highest antimicrobial activity was exhibited by the glacialacetic acid extract against P. mirabilis. Thepresence of various bioactive compounds justifies the use of this plant forvarious ailments by traditional practitioners. However, isolation of individualphotochemical constituents and subjecting it to biological activity willdefinitely give fruitful results.

Keywords: Antibacterial activity, Azulene, Campesterol, Cenchrus grass and Myristic acid,isopropyl ester.
