Abstract

The invention relates to a method for extracting tea saponin by adopting a tea seed cake, comprising the following steps of: firstly smashing a dry tea seed cake after tea seed oil is extracted, and then placing into a reaction vessel; adding the petroleum ether with the mass concentration of 90-95 percent according to a proportion of the mass/volume ratio of 1:3, and stirring at constant temperature for reaction at the temperature of 55 DEG C to carry out derosination for 1 hours, and filtering after the reaction, wherein the mass of tea seed powder is expressed as grams and the volume of petroleum ether is expressed as ml;; drying filtered filter residues, and then placing into the reaction vessel; adding ethanol with the mass concentration of 80-95 percents according to the proportion of the mass ratio of 1:5-7, and stirring to carry out reflux extraction at 65-75 DEG C by two times for 1.5-3.5 hours, and filtering filter liquor when the filter liquor is hot; distilling the filter liquor, and concentrating to one tenth of original volume at temperature which is not higher than 60 DEG C; adding acetone equivalent to two times of the liquid volume of concentrated liquor to the concentrated liquor for extraction, wherein faint yellow sediments are generated during the extraction; and carrying out vacuum drying on filter residues to obtain faint yellow rough saponin at normal temperature or low temperature.

Description

technical field [0001] The invention relates to a method for preparing a tea saponin nonionic surfactant extracted from tea seed cake with ethanol and acetone, that is, a method for preparing a green surfactant tea saponin. Background technique [0002] Tea saponin is a kind of pentacyclic triterpene saponins extracted from the seeds or leaves of Camellia plants, and it is a pure natural saponin. It is a non-ionic surfactant with the properties of emulsifying, dispersing, wetting and foaming. It has pharmacological effects such as impermeability, anti-inflammatory and analgesic. It also has the functions of sterilizing insects and stimulating the growth of certain plants. It is widely used: it is used as degreasing agent, emulsifier and wear reducer in industry; it is used to make detergent and shampoo, which has incomparable advantages of other chemical synthetic products; its pure product can be used as a therapeutic agent in medicine. Drugs for diarrhea, edema and senile...
