Phytochemical profiling and anti-bacterial activity of Erycibe paniculata ROXB.

Abstract

Erycibe paniculata Roxb. Is an ethno medicinal climber belongs to family Convolvulaceae commonly called Unamkodi in Tamil and Putta palatige in Telugu. It is found in India, Himalayas and Andaman Islands, has many ethno medicinal properties. Survey of literature on pharmacognosy and phytochemistry has elucidated that there are several ethnomedicinal plants which have been systematically studied for their pharmacognostic and phytochemical profiles. Crude drugs of a large number of ethnomedicinal plants are not investigated scientifically. Keeping this scenario in mind, the present study is planned to investigate phytochemical profile and also antibacterial activity of leaf extracts of Erycibe paniculata Roxb. Solvent extraction is carried by soxhlet method using different solvents based on their polarity and their yield percentages are calculated. Acetone and n-hexane showed high yield percentages compared to other solvents. The phytochemical tests were performed using standard methods that were reported and antibacterial activity is done by agar well diffusion method. For antibacterial activity we used two gram positive methicillin resistant Staphylococcus aureus and Bacillus subtilis and two gram negative bacteria- Pseudomonas aeruginosa and Escherichia coli. Ethyl acetate has shown maximum zone of inhibition towards all the bacteria tested and least is shown by toluene.
