Abstract

Singkil leaves (Premna corymbose Roxb & Willd.) are a plant that is widely found in Kalimantan, and usually grows in the yard of houses or plantations. A research on phytochemicals screening and antioxidant activity test of singkil leaves (Premna corymbose Roxb & Willd.) using DPPH (1,1- diphenyl-2-picrylhydrazyl) method had been conducted. Test for alkaloids, triterpenoids/steroids, phenolic, flavonoids, saponins, and quinone were included in phytochemical screening. The results of the literature show that the methanol extract exhibits antioxidant activity in the strong category, which has an IC50 value of 20.66 μg/ml. Methanol extract of singkil leaves (Premna corymbose Roxb & Willd.) has potential as an antioxidant. Keywords: Singkil leaves (Premna cordifolia Roxb.), phytochemical screening, antioxidant, DPPH

Abstract

Antioxidant and sunscreen activity tests have been carried out on the methanol extract of singkil leaves(Premna corymbosa Roxb & Willd.) in vitro with the 1.1-diphenyl-2-picrylhydrazil (DPPH) radicalscavenging method using a spectrophotometer UV-Vis. This research aims to determine the antioxidantof singkil leaf. Based on the results of the phytochemical test, it is known that the methanol extract ofsingkil leaves contains alkaloids, flavonoids, phenolics, quinone and steroids. The IC50 value ofmethanol extract of singkil leaves, ia 50.77; in the moderate to strong antioxidant category.
