Evaluation of hexane extract of parkia speciosa hassk. pericarp as a potential antimicrobial agent / Nurul Afiqah Ahmad Zaidi

Parkia speciosa Hassk. or locally named as “Petai” in Malaysia, belongs to the family Fabaceae. It is known to have many medicinal benefits. In the present study, the discarded pericarp of Parkia speciosa was extracted with n-hexane solvent for assessment on its antimicrobial activities. Antimicrobi...
