A Phytochemical and Antioxidant Activity of Extracts Red Cambodia Sap (Plumeria Rubra L.)

Abstract

Red Cambodian (Plumeria rubra L.) is a medicinal plant cultivated by the community with antimicrobial, anti-cancer, and antioxidant bioactivity. This research aims to obtain information regarding secondary metabolite content by phytochemical testing on red Cambodian sap (Plumeria rubra L). Phytochemical screening is carried out by looking at the colour-testing reaction using a reagent of methanol and n-hexane. The antioxidant test was carried out using DPPH (1,1-diphenyl-2-picrylhydrazyl) at a wavelength of 517 nm. The results showed that the methanol faction contained alkaloids and saponins. Meanwhile, the n-hexane fraction contained flavonoid compounds, tannins, terpenoids and saponins. The antioxidant test was based on the IC50 calculation; the n-hexane fraction had an IC50 value of 19.8282 mg/L.
