Phytochemical screening and total phenolic content of Mansonia gagei leaves

Abstract

This research aimed to investigate the phytochemical screening and total phenolic content of Mansonia gagei leaves. As the phytochemical screening testing by color reaction, nine groups of phytochemical constituents, alkaloid, flavonoid, coumarin, saponin, tannin, phlobatannin, terpenoid, steroid and cardiac glycoside, were found. Total phenolic content (TPC) was analyzed by Folin-ciocalteu method and compared to gallic acid calibration curve (y = 0.0115x, R2 = 0.9987). As the result, the TPC of the crude extract of M. gagei leaves displayed 48.356±0.695 mgGAE/g crude. Therefore, the results showed that M. gagei leaves can be used as a phytochemicals source. In addition, the results can be used as the phytochemicals data for further benefits in pharmaceuticals, cosmetics or food industries and adding the value of M. gagei leaves that are the medicinal plants found in Thailand.
