Embodiment 1

[0081] Add 1000g of 75% ethanol to 1000g, add 6L of 75% ethanol, heat and reflux for extraction for 1 hour, and extract the filter residue twice with 75% ethanol, 6L each time, heat and reflux for 1 hour, filter, and combine the filtrates. The filtrate was concentrated to a certain extent, extracted with n-butanol (500ml×4), the n-butanol was washed with water, then concentrated and dried, and the obtained solid was washed with petroleum ether, filtered, and the solid was recovered to obtain the total glycosides of radix chinensis, with a yield of 3.6%. Its total glucoside content was measured to be 49.4%.

Embodiment 2

[0083] Add 1500g of Baiying, add 7L of 50% ethanol, heat and reflux for extraction for 1 hour, and extract the filter residue twice with 50% ethanol, 5 L each time, heat and reflux for 1 hour, filter, and combine the filtrates. The filtrate was concentrated to a certain extent, and extracted with petroleum ether. After the extraction, the D101 macroporous resin on the water phase was washed with water and 20% ethanol in turn, and then eluted with 50% ethanol. The eluate was concentrated and dried to obtain total glycosides of astragalus. Its total glucoside content measured is 65.3%

Embodiment 3

[0085] Add 1500g of Baiying, add 7L of pure water, heat and reflux for extraction for 1 hour, and extract the filter residue with pure water twice, 5L each time, heat and reflux for 1 hour, filter, and combine the filtrates. The filtrate was concentrated to a certain extent and extracted with petroleum ether. After extraction, the D101 macroporous resin on the water phase was eluted with water-20% ethanol-50% ethanol-95% ethanol in sequence, and the 50% ethanol eluted parts were collected and concentrated to It has no alcohol smell, is concentrated and dried to obtain the total saponin extract of Baiying, and the total glycoside content is 59%.
