Abstract

This research aimed to determine the yield, total phenolic content (TPC), in vitro sunscreen (SPF), and antioxidant activities (AA) of Damonorops draco resin (DDR). The DDR was macerated with ethanol at various concentration (EC) namely 100% (E100), 90% (E90), 80% (E80), and 70% (E70) and the DDR:solvent ratio (D:S) were 1:5, 1:10, and 1:15. This research showed that the interaction between the EC and D:S affected AA, SPF, and TPC of DDR extract (DDRE), but it didn't affect the DDRE yield. The DDR extraction with E70, E100, and D:S of 1:15 produced the highest DDRE yield. The extraction with E70 and three different D:S produced DDRE with the highest TPC. The highest AA of DDRE was obtained from extraction with E80 and D:S 1:10 (E80-10), E70-15, and E90-5 respectively. The highest SPF of DDRE was obtained from the extraction with E90-15, E70-15, E90-5, and E70-10, respectively. The extraction with E70 and D:S of 1:15 is the best extraction condition because it produces DDRE with a yield of 17.4±3.9%-20.71±1.6%; TPC of 263.93±5.25 mg GAE/g DDRS; AA with an IC value of 78.3±0.3 ppm, and sunscreen with an SPF value of 33.1±0.0.
