Antibacterial activity of ethyl acetate extract from Parkia speciosa pericarp against selected bacteria / Norfarah Izzaty Razaly

Parkia speciosa which is also known as petai is commonly found in tropical countries such as Thailand, Indonesia and Malaysia. This plant is usually eaten raw, as flavor to cuisine and pickled in salt. Besides, folks also believed that Parkia speciosa have the ability to treat kidney inflammation an...
