Study On The Extraction And Quality Control Method For Saponins And Polysaccharides From Momordica Charantia L.

The paper investigate the extraction artwork and quality control of saponins and polysaccharides from momordica charantia L.. Extract the crude saponins with water-alcohol and the crude polysaccharides with water from momordica charantia L. ,then purify the crude saponins with resin monitoring by near infrared transmission spectrum(NIRTS). On the condition of optimum, the purity and extraction ratio of the saponins and polysaccharides are stationary. The crude saponins'extraction ratio is 3.06% and the content is 7.69%, after purifying with AB-8 resin, the content is about 50%. The crude polysaccharides extraction ratio is 1.34% and the content is 28.5% on the optimum condition. The method can degrade the extraction cost of the saponins and polysaccharides from momordica charantia L.. The NIRTS method can monitor the process of the saponins purify with AB-8 resin.
