| preparation | A method for preparing A high-purity semen ziziphi spinosae saponin A reference: A. Raw material extraction: the semen ziziphi spinosae is added to 5-8 times the amount of ethanol solution according to the volume mass ratio L/Kg, and the volume percentage concentration of the used ethanol solution is 60-75%; the semen ziziphi spinosae and the ethanol solution are heat-extracted at least 2 times at 60 ° C. For about 2 hours each time, cooled to room temperature, suction filtered, and the filtrates are combined and concentrated to have no alcoholic taste; B. Macroporous resin enrichment: the concentrated solution of Step A is statically adsorbed with macroporous resin overnight, and then impurities are eluted with 2-3 times the volume of column water and 2-5 times the volume of Column 15-30% ethanol solution, the target substance was eluted with 50-65% ethanol solution 1-3 times the volume of the column, and the eluate was collected and concentrated to 1/10 of the original volume; C. Extraction: adding 1-2 times the amount of n-butanol to the concentrated solution of Step B, extracting, collecting the n-butanol layer, and concentrating to obtain the alcohol extract of ziziphi spinosae saponin a described in step (I); D. Medium pressure preparation: Step C of the alcohol extract of semen ziziphi spinosae saponin A was dissolved in 50% acetonitrile water on medium pressure preparation column, Eluted with 30% acetonitrile and concentrated to obtain A semi-finished product of semen ziziphi spinosae saponin A with A purity of about 60%; E. Gel purification: about 60% of crude semen ziziphi spinosae saponin A obtained in step D was purified by dissolving in 50% methanol water on gel column, washed with 50% methanol water, and detected by HPLC, the target fraction was collected, concentrated and freeze-dried to obtain crude semen ziziphi spinosae saponin A with A purity of about 95%; F. High-pressure preparation: about 95% of crude semen ziziphi spinosae saponin A obtained in Step E was dissolved in 58% methanol water, high-pressure preparation was carried out, and 58% methanol water was washed off to collect A target fraction; G. Product recovery: the high-pressure fraction obtained in step F was concentrated and freeze-dried to obtain A reference product of ziziphi spinosae saponin A with A purity of 100%. |
| uses | semen ziziphi spinosae saponin A has sedative, hypnotic, anti-aging, anti-atherosclerosis and anti-cancer effects. for content determination/identification/pharmacological experiments. Pharmacological Efficacy: anti-arrhythmic effect. |
