Abstract

Rafflesia cantleyi (Rafflesiaceae) is a parasitic flowering plant scarcely found in the Peninsular Malaysia. The bud of this plant is sought after by folk medicinal practitioner for various uses by men and women. Scientific evidences on this plant are however limited. In this study we explored the antioxidant activity, total phenolic content and the total flavonoid content of the aqueous extracts from R. cantleyi bud parts including disk, perigone tube and bract. The antioxidant activity was determined by employing three different systems including scavenging activity of 2, 2-diphenyl-1-picrylhydrazyl radicals (DPPH), hydrogen peroxide (H<inf>2</inf>O<inf>2</inf>) scavenging activity and Ferric Reducing Antioxidant Power (FRAP). The antioxidant activity of bract extract was higher than those of perigone tube and disk. Total phenolic and total flavonoids contents were significantly higher (p<0.05) in the bract compared to perigone tube and disk. Strong correlation between total phenolic and antioxidant properties was indicated. The result of this study showed that bract of R. cantleyi bud possesses significant free radical scavenging property with this antioxidant activity contributed by the phenolic compounds. The results supported the traditional medicinal use of the bract as energy drink which is due to its natural sources of antioxidants.
