Abstract:
Dietary antioxidants include enzymatic and non-enzymatic antioxidant as well as
bioactive plant phenols. The health benefits of 'ulam' are largely due to the
antioxidant vitamins supported by the large number of phytochemicals, some with
greater antioxidant properties. So, the objective of this study were to determine and to
compare the level of antioxidative constituents; carotenoid, ascorbic acid, a
tocopherol concentration as well as catalase (CAT), ascorbate peroxidase (APx) and
guaiacol peroxidase (POD) specific activities in S. androgynus and P. sarmentosum.
P. sarmentosum contained significantly higher concentration of carotenoid as well as
POD specific activity while S. androgynus contained significantly higher CAT
specific activity compared to P. sarmentosum. There were no significant differences
in ascorbic acid and a-tocopherol concentration, as well as in APx specific activity in
P. sarmentosum and S. androgynus. Results revealed that both 'ulam' are a good
sources of a natural dietary antioxidant for human.
