Antimicrobial Activity of Methanolic Root Extract of Decalepis hamiltonii Wight & Arn

Full Text PDF


The present study was quantitative analysis and antimicrobial activity of petroleum ether, chloroform, ethyl acetate, methanol root extracts. The gram positive and gram negative bacterial and fungal species by the disc diffusion method at various concentration (250μl-1000μl). The results was present in the phenolic and flavonoid content compared to extracts. All the root extract against to Bacillus subtilis and Streptococcus pyogenes and fungal species Candida albicans at highest inhibition at concentration of methanolic root extract of zone formation. The preliminary studies on Decalepis hamiltonii root extract exhibited their antimicrobial potential which could be exploited further and future pharmaceutical, therapeutic efficiency and food preservation and applications.
