Enrichment of skin lotion with antioxidant from Rhizophora mucronata fruit extract

Abstract

Rhizophora mucronata is one of mangrove species that are located in coastal plates and the growth is affected by the tides of the sea. This type of mangrove population is concentrated in the areas of Papua, Kalimantan, Sulawesi, and Sumatra. Mangrove population in Indonesia reaches 75% of the entire mangrove population of Southeast Asia, or about 27% of total world mangrove population. This fruit source of bioactive components like tannin, flavonoid, saponin, phenol and hydroquinone. Those bioactive components as antioxidant for skin lotion product. The purpose of this research was to know the effect of addition of different concentration of R. mucronata extract to the characteristics and to know the best concentration on the addition of R. mucronata extract. Materials used R.mucronata fruit which is taken from Kaliprau Village, Ulujami Regency Pemalang and made powder finely. Research method used is Completely Random Design (RAL), each 3 times repetition with non-parametric data analysis using Kruskal-Wallis and analysis of parametric data using ANOVA and HSD test. The results of preliminary study showed R.mucronata fruit extract containing flavonoid 65.63 ppm; phenol 4,333 ppm; saponin 9.41%; alkaloid 21.11% and positive steroids. The IC50 extract was 135.69 ppm. The results of the addition of the extract concentration of 0, 3, 5 and 7% showed that the skin lotion with R.muconata 5% extract had the best hedonic result 4.66-5.25; viscosity 3,615 cp; pH 8.08; 100% emulsion stability, Sun Protection Factor value 10.87% and percent inhibition 79 % and the results have been in accordance with Indonesian National Standard SNI 16-4399-1996.
