Antimicrobial activity and phytochemical screening of Cynodon dactylon and Carica papaya

Abstract

Presence of various phytochemical compounds in Cynodon dactylon and Carica papaya was qualitatively and quantitatively determined by various standard method of analysis. The suitable extraction method was identified for phytochemical compound extraction from the above selected plants. The present study revealed that ethanol is a suitable solvent system which showed the presence of high percentage in the range of 0.01 to 1.46 and 0.02 to 10.0 percentage of phytochemicals compared to other solvent extracts. The moderate percentage 0.01 to 1.0 and 0.00 to 0.7 percentages is obtained in chloroform extraction system and least is 0.00 to 1.04 and 0.01 to 0.64 percentage of constituents in acetone extract, very lowest percentage of phytochemical constituents was observed in the range of 0.00 to 0.03 and 0.00 to 0.04 percentage in hot water extraction system. The selected plants have wide range of phytochemical constituents, hence further structural elucidation of such bioactive compounds is essential to study their traditional use.
