Abstract
Research on antioxidant activity of Marchantia in Indonesia is still limited. The objective of the study is to investigate the antioxidant activity of Marchantia paleacea from North Sumatera, Indonesia. The method of extraction in this study using maceration with methanol. The antioxidant activity of extracts were evaluated by 1,1diphenyl-2-picrylhydrazyl (DPPH). Vitamin C was used as positive control. The results showed that the extract of M. paleacea has antioxidant content with LC50 value of 25.25 μg/mL. The antioxidant activity of M. paleacea is classified as a strong category.
