Phytochemical properties and antimicrobial and antioxidant activities of Uvaria micrantha (A.DC.) Hook. f. & Thomson

Uvaria micrantha (A.DC.) Hook. f. &Thomson is a medicinal plant species used by local people in Malaysia. However there are limited scientific evidence to validate the medicinal properties of U. micrantha. In this study, phytochemical screening of the leaf extracts of U. micrantha using methanol...
