Abstract
Modem scientific researches have proven that plants contain plenty of antioxidants that can combat over-produced reactive oxygen species. It has been reported that the roles of fmits, vegetables and red wine in disease prevention have been attributed, in part, to the antioxidant properties of their constituents including Vitamins C and E, carotenoids, phenolic acids, flavonoids and so on.
Flavonoids possess unusual structures that contribute to their characteristic chemical properties so as to become promising antioxidants. Their diversity and abundance in plants perhaps would give us a chance to find out certain potential applications in the fields of biology and pharmacy. Fortunately, Singapore, located in the tropics and richly endowed by nature, is full of diverse and numerous kinds of plants. These cheap and plentiful plants/herbs offer us so much convenience to
undertake studies on antioxidants from the plants. Thus, our research project was started with a study on flavonoids from local plants.
The main objectives of this study are (a) to isolate and purify flavonoids from two selected local plants, Balsam flowers and Laksa leaves, (b) to identify the main flavonoids present in each of the above-mentioned plants, and (c) to measure the antioxidative capability of the identified flavonoids by ESR and ABTS-UVIVIS evaluations.
