Antinociceptive, antimicrobial potential and phytochemical screening of different solvent extracted samples from the stem of Acer pentapomicum

Abstract

The present study investigates the antinociceptive, antimicrobial activity and phytochemical assessment of samples from A. pentapomicum. Different microbes were tested using disc diffusion assay at three concentrations (1, 2 and 3 mg/disc). Antinociceptive activity was determined by acetic acid induced and hot plate methods. The tested plant extracts revealed significant antinociceptive activity at dose dependent manner when measured by acetic acid induced method. The growth of all the tested microbes was inhibited by methanol, butanol, and ethyl acetate extracted samples at all concentrations. Chloroform, n-hexane and aqueous extracts inhibited the growth of the different microbes at high concentration. The most susceptible microbe was P. aeruginosa measuring 94% and 79% zone of inhibition by butanol and ethyl acetate extracts at 3mg /disc. C. fruendii, however, was the most resistant bacterium followed by S. aureus. The presence of alkaloids, proteins, amino acids, carbohydrates, flavonoids, tannins, saponins, and fats were confirmed in phytochemical screening of different extracts.
