The purpose of this research was to analyze the factors affecting the extraction of saponin from rambutan seeds, such as material size, solvent concentration (ethanol), material / solvent ratio and extraction time. Rambutan seeds were purchased from Tuc Duyen market in Thai Nguyen City. The seeds were separated from the pulp then dried to a moisture content of about 8% to use for experiments. The results showed that the suitable material size was 1.2 mm, the best extraction ethanol concentration was 70%, the extraction solvent rate was: 250ml / 5g of raw material and the extraction time was 3 hours for the highest saponin.
