Examination was made of the conditions for the extraction, critical micelle concentration (cmc) and detergency of saponin from plants. Extraction volume was maximum at 100°C over a period of 1∼3 hours. To control saponin concentration, cmc of this compound had to be determined by the conductivity method. The detergency of standard soybean saponin was maximum at 1.2 times cmc, pH10.0 for 30 minutes at 40°C. Extraction exceeded that of the model detergent by 70%. The extraction of saponin from adenophora, mandarin orange, adzuki bean, soybean was 40% in each case.
