Author: NENI GUNARTI, ANGGUN HARI KUSUMAWATI, MAYA ARFANIA, FARHAMZAH, IIN LIDIA PUTAMA MURSAL
Abstract: This research was conducted to determine the antioxidant and sunscreen activity of blackberry extract (Rubusfruticosus). Antioxidant activity was tested using the 1.1 Diphenyl-2- picrylhidrazyl (DPPH) method using UV-Visible spectrophotometry. Sunscreen activity is also carried out in vitro using UV-Visible spectrophotometry. The results showed that Blackberry ethanol extract had weak antioxidant activity with IC50 407.5175 ppm and erythema% sunscreen at concentrations starting from 0.75% including total Block,% pigmentation at concentrations starting from 0.25% including total Block and SPF values above 30 (ultra) at concentrations starting from 0.75%. This shows that blackberry extract has weak antioxidant activity but has potential as a natural sunscreen ingredient.
