Resveratrols from the stembark of shorea ovalis (meranti kepong) (dipterocarpaceae) and antioxidant activity / Rosmawati Abdul Aziz and Norizan Ahmat
Dipterocarpaceae is a plant family of large tree that is widely distributed in the tropical rain forest of Southeast Asia, such as Borneo and Peninsular Malaysia. Shoreais the largest genus of Dipterocarpaceae and the most economically important in Malaysia. Locally, Shorea...
