Abstract

Ornamental plants are one of the resources that have the potential to be developed on a large scale due to high public interest. The dollar leaf plant is one of the most common ornamental plants. The leaves of the dollar plant are commonly used in traditional medicine. The objective of this research was to determine the antioxidant properties by means of the 2,2 diphenyl -1-picryhidrazil (DPPH) method from the methanolic extract of dollar leaf (Ficus pumila L.). Based on the results of phytochemical tests, the methanol extract is known to contain alkaloids and steroids. The dollar leaf methanolic extract showed antioxidant activity with an IC50 value of 387.753 mg/mL. From the antioxidant activity test results, dollar leaf methanol extract has relatively weak antioxidant power. Keywords: dollar leaf, antioxidant, 2,2 diphenyl -1-picryhydrazyl (DPPH) method, extract

Abstract

This study was conducted with the aim of identifying the antibacterial activity of crude ethanol extract, ethyl acetate fraction, methanol:water fraction and n-hexane fraction of white pacing flower (Costus speciosus (J. Koenig) Sm.). Sample preparation was carried out using the extraction method, namely maceration with 96% ethanol and obtained a crude extract of ethanol and continued by partition by liquid-liquid extraction method and obtained the n-hexane, the ethyl acetate, and the methanol:water fractions. The antibacterial activity test was carried out on the four samples using the well diffusion method with modification against Escherichia coli ATCC 25922. The antibacterial activity test showed activity in the crude extract of ethanol with an inhibition zone diameter of 7.7 mm. Keyword: white pacing, antibacterial, Escherichia coli
