Abstract:
Malays traditional vegetables in Malaysia are consumed because of their taste as well
as for their health benefit. Nutritional studies have indicated that many of these
vegetables supply the human body with essential dietary antioxidant component. The
concentrations of antioxidative constituents ( a-tocopherol, ascorbic acid and
carotenoid content as well as catalase (CAT), guaicol peroxidase (POD) and ascorbate
peroxidase (APX) specific activities) were studies in the leaf tissues of Oenanthe
javanica (selom) and Mahinot esculenta (pucuk ubi). Result showed that Oenanthe
javanica exhibited significantly higher concentration of a-tocopherol, ascorbic acid as
well as ascorbate peroxidase specific activities as compared to Mahinot esculenta.
However, the carotenoid content, catalase and guaiacol peroxidase specific activities
were significantly higher in Mahinot esculenta compared to Oenanthe javanica.
