Abstract
Abstract The Phyllanthaceae family encompasses a diverse range of flowering plants with significant ecological and cultural relevance. In the geothermal area of Ie-Brôuk in Aceh Province, Indonesia, two species from this family, Baccaurea pyriformis Gage and Antidesma montanum Blume, were investigated for their antioxidant activity. This study focused on the phytochemical composition and antioxidant activity of three different extracts ( n -hexane, ethyl acetate, and ethanol) of these plants. Phytochemical screening of the extracts using six different tests revealed the presence of saponins, steroids, and tannins, with steroids consistently detected across all solvents. The antioxidant activity of the most active extract was quantitatively assessed using the 2,2-azinobis-(3-ethylbenzothiazoline-6-sulphonate) radical cation or ABTS assay, revealing that the ethanolic extract of A. montanum exhibited superior antioxidant properties, with an inhibitory concentration (IC 50 ) value of 45.63 ppm, compared to B. pyriformis , which showed an IC 50 value of 63.94 ppm. The statistical analysis used a Student t-test revealed a significant difference in IC 50 values between the two plant extracts. The presence of these secondary metabolites, particularly the steroids, suggests the potential for these species to serve as natural antioxidant sources. The findings underscore the pharmacological potential of these plants, particularly A. montanum , as a promising candidate for developing new antioxidant agents, reflecting the unique environmental and biological characteristics of their geothermal habitat.
