EFFECTIVITY OF ETHANOLIC EXTRACTS FROM JAMBULANG FRUIT (SYZIGIUM CUMINI. L) AS ULTRAVIOLET ANTI RADIATION AGENT.

Abstract

This study aims to determine the effectiveness of ultraviolet anti-radiation agents on Jambulang ethanolic extract (Syzigium Cumini L) by calculating SPF,% T, and% Tp values in UV A and UV B wavelengths with concentration variation of 1 ppm, 10 ppm , 100 ppm and 1000 ppm. The preparation of jamblang fruit extract was done by maceration method using ethanol solvent. Measurement of absorbance value of the extract is by using UV-Vis spectrophotometer. The measurement result calculates SPF,% Te, and% Tp. The calculation results show the wavelength of UV A with concentration of 1 ppm, 10 ppm, 100 ppm, and 1000 ppm, where% Tp in the sunblock category has the value of 1.129; 1,126; 1,138; 1,142 and SPF with minimum protection category at concentration 1 ppm and 10 ppm has the value equal to 3,311 and 3,758, medium protection at concentration 100 ppm has the value equal to 4,989 and ultra protection at concentration 1000 ppm has the value equal to 315,5. UV B with% Te in the ultra-protection category has the value of 1.133; 1,158; 1,232; 2,731 and SPF with minimum protection category at concentration 1 ppm and 10 ppm has the value equal to 2,280 and 2,979, moderate protection at concentration 100 ppm has the value equal to 5,346 and ultra protection at concentration 1000 ppm has the value equal to 13002. Introduction:-Ultraviolet radiation can be divided into three kinds, namely UV-A radiation with a wavelength of 320-400 nm, UV-B radiation of 280-320 nm and UV-C radiation of 100-280 nm (Nuverry, 2012). UV-A radiation has a longer wavelength compared to UV-B and UV-C, but has a smaller energy so the shorter the wavelength the higher the hazard (Rini, 2014). Many ways have been done to prevent the negative impact of UV radiation, one of them by using anti-radiation agent UV. These compounds utilized chemical molecules as anti-ultraviolet radiation capable of absorbing and deflecting ultraviolet radiation to protect human skin health from the negative impact it generates (Lavi, 2012). Products that produced are found in various forms, there are shaped powders, gels, lotions, and cream. These products then have side effects from their synthetic ultraviolet anti-radiation compounds, therefore, some formulations are now emerging by utilizing active compounds derived from plants as ultraviolet anti-radiation agents. Plants have photoprotective natural substances that can be extracted, this is associated with the ability of plants to receive sun exposure because plants need sun for photosynthesis (Prasidda, et al., 2016). It provides an
