Abstract
Polysaccharide production from the aerial parts of Plantaoo asiatica L. was carried out using water decoction. Response surface methodology (RSM), based on a five level, four variable central composite design (CCD), was employed to obtain the best possible combination of extraction time (X1: 1-5 h), extraction temperature (X2: 60-100 °C), number of extraction (X3: 1-5), and ratio of water to raw material (X4: 10-30) for maximum polysaccharide production. The experimental data obtained were fitted to a second-order polynomial equation using multiple regression analysis and also analyzed by appropriate statistical methods (ANOVA). The optimum extraction conditions were as follows: extraction time of 3.9 h, extraction temperature of 91 °C, number of extraction of 4, and ratio of water to raw material of 24. Under these conditions, the experimental yield was 4.37 ± 0.13%, which is well in close agreement with value predicted by the model.
