Yam mention � � content of effective component
the main effective components in Chinese yam saponins and aglucone yam diosgenin, also check bifurcation, element, 3, 4 - Dihydroxy phenethylamine, mannan, phytic acid, alkali, dopamine, yam, maple Ⅱ, cholesterol and ergosterol, campesterol, beta Sitosterol, allantoin, yam Ⅰ etc.
process method of extracting effective components in Chinese yam
1. Water extract yam
water is the most simple, the most common method of extraction, but its characteristic is time-consuming, extraction efficiency is not high. By water leaching liquid ratio, extraction temperature and extraction time.
2。 Ultrasonic extraction method to extract the yam
ultrasonic extraction method is the use of ultrasonic effect on cell wall broken, promote the dissolution of intracellular polysaccharides, improve gain rate, shorten the extraction time.
3。 Solvent extraction combined with traditional Chinese medicine extraction equipment to extract yam
in the solvent extraction method is to use yam compound in two mutually miscibility ( Or slightly soluble) Solubility in solvent or the distribution coefficient of the different, make the compounds from within a solvent to another solvent. After repeated many times extraction, will most of the compounds are extracted.
solvent extraction combined with traditional Chinese medicine extraction equipment to extract yam advantages
in the mountains tablets after crushing, alkalization, extraction, yam polysaccharide mainly dissolved in the water extraction liquid; After adjust pH, yam polysaccharide free out from the water, then use extraction solvent for extraction, the yam polysaccharide into the extraction agent, and then continue to complete follow-up purification crystallization operation.
in Chinese yam polysaccharide extraction process, the traditional mode of operation is tank stirring extraction, artificial to separate two phase after stratification by gravitational force, the intermittent operation is more tedious, a longer production cycle. By using. cwl - M new centrifugal extraction machine can not only overcome the above shortcomings, but also can make the extraction period of continuous production, separating the two more completely, less dosage of extraction solvent, extraction rate is higher, etc.
