Antioxidant activity of pitcher extracts from three Nepenthes species

Nepenthes, locally known as ‘periuk kera’ in Malaysia, is a fascinating species due to uniqueness in their morphology in having pitcher organ for carnivorous diet. The pitcher plant has been used for cooking traditional delicacies and as traditional remedies to treat illness. Hence, this species mig...
