Amaranthus tricolor L. was reported as source of carotenoid compounds (tetraterpenoids) which is a natural pigments and has bioactivity as antioxidants. They are beneficial to health. Carotenoids isolate are obtained by maceration method in methanol, saponification with KOH / MeOH 5%, fractionated by vacuum column chromatography, preparative thin layer chromatography (preparative-TLC) repeatedl…
The main compound of Uncaria gambir Roxb. (gambir), catechin and it’s derivates have been believed to be potential as antiviral. Epigallocatechin gallate (EGCG) and epicatechin are catechin derivates which are found to be potential as antiviral against Human Immunodeficiency Virus (HIV). However, gambir extract also contains quercetin that has possibility to be mutagenic. Therefore, a pre…
