Abstract

The objectives of this study were to determine the phytochemicals in Thai medicinal plant extracts and to screen the antioxidant activity of the extracts. Thai medicinal plant used in this research were C. garrettiana, P. merkusii, D. parviflora, T. hoaensis, D. loureiri, T. siamensis, M. elengi, E. antiquorum, P. ribesoides and O. indicum. The phytochemical including reducing sugars, anthraquinones, terpenoids, flavonoids, phenolic compounds, saponins, tannins, alkaloids, cardiac glycosides and proteins were screened. All plant extracts contained terpenoids, flavonoids and phenolic compounds. The antioxidant assays used were DPPH and FRAP. P. ribesoides and D. parviflora exhibited the most potent antioxidant activity, and this was associated with the data of total phenolic and flavonoid contents those were responsible to the anti-oxidative ability of the extracts. The results revealed the potential uses of the medicinal plant extracts as the dietary supplements as free radical scavenger. Moreover, they could be used as active ingredients in cosmetic formulations.
