The study will be focusing on (1) in-depth evaluation of some important chemical compositions of son tra such as triterpene acid, polyphenol and organic acids and (2) preparation of some semi-finished products from Son tra (in water extract form) as pre-product for producing instant tea, son tra gel and their standardization. The analysis of the study has been conducted at quality analysis laboratory. The result shows that the most essential chemical substances of son tra fruits are triterpene acids, polyphenols and organic acids. The tested son tra products in this study include instant tea and son tra gel proved to be acceptable with simple technology, low cost and low investment.
