Abstract

Oyong (Luffa acutangula L) is a type of plant that grows in many tropical areas. Oyong (Luffa acutangula L) is often consumed by the public because it is often found and contains vitamin C. The purpose of this study was to determine the content of vitamin C levels in oyong (Luffa acutangula L) samples using the UV spectrophotometric method. The clean oyong(Luffa acutangula L) is then blended using a juicer extractor and cleared using a centrifuge. The determination of the content of vitamin C content in this oyong used the UV spectrophotomeetric method at a wavelength of 266,5 nm and a qualitative test was carried out. The qualitative test result showed that oyong (Luffa acutangula L) was posotive for vitamin C The average level vitamin of vitamin C is 0,024% withcoefficient variation of 1,46%.
