Abstract

The mangosteen peels (Garcinia mangostana L.) has high free radical scavengers activity. This study aims to determine the physical and chemical conditions that are formulated in SNEDDS and nanoemulsion preparations. SNEDDS was made with various concentrations of Tween 80, PEG 400, and Virgin Coconut Oil (VCO) with a ratio of 4,98:1,02:1. Nanoemulsions were made with the addition of water to SNEDDS. Stability observation results were analyzed by statistics. The results of physical stability test show that all test samples in the research, in nanoemulsion, SNEDDS fraction, base SNEDDS, SNEDDS vitamin E did not undergo separation, precipitation, cracking, and creaming. On the chemical stability test of nanoemulsion and SNEDDS fraction there is no difference between IC50 before and after storage. While on basic SNEDDS and vitamin E nanoemulsion there is a difference between IC50 before and after storage.

Abstract

Research of radical scavenging activity of sambiloto (Andrographis paniculata Nees) and patikan kebo (Euphorbia hirta L) ethanolic extracts and their combination toward 2,2-Diphenyl-1-Picrylhidrazyl (DPPH) has conducted. Subjects of this experiment comprise sambiloto ethanolic extract, patikan kebo ethanolic extract, dechlorophyllated extract of sambiloto and combinations among those three. Dechlorophyllation by electrocoagulation method is done to reduce chlorophyll content thereby increasing the level of active compound in the sambiloto extract. The results of dechlorophyllation showed that only total flavonoid content in the extract of sambiloto increased, meanwhile the radical scavenging activity results showed that patikan kebo ethanolic extract has the lowest IC50 value (22,36 µg/mL) compared to sambiloto ethanolic extract (IC50 value 499,03 µg/mL). Extract combination may increase DPPH radical scavenging activity of the sambiloto extract (IC50 value 76,06 µg/mL) but not higher than that of patikan kebo single extract.
