Embodiment 1
[0016] Example 1: Preparation of Robin-7-O-rhamnoglucoside
[0017] Take 2kg of thistle herb, extract twice with 22L of 80% (v / v) ethanol under hot reflux, each time for 2 hours, collect the extract, recover the ethanol under reduced pressure until there is no alcohol smell, place it at room temperature, centrifuge, and collect the precipitate. The above precipitate was degreased with dichloromethane. Add 1L of 5% sodium hydroxide solution to the precipitate after degreasing, then add 0.5L of ethanol, stir to dissolve, filter, take the filtrate, adjust the pH to 6-7 with 35% concentrated hydrochloric acid, precipitate the precipitate, suction filter, filter the cake separately After being fully washed with 50% (v / v) ethanol and distilled water, dried and pulverized, the acaciacin-7-O-rhamnoglucoside was obtained with a content of 97.9% (W / W).
Embodiment 2
[0019] Take 2 kg of thistle medicinal material, crush it into a coarse powder, add 25 L of 70% (v / v) ethanol (containing 1% sodium hydroxide) to warm and extract three times, each time for 6 hours, collect the extract, and recover the ethanol under reduced pressure to nothing. Alcoholic taste, put it at room temperature, adjust the pH to 6-7 with glacial acetic acid, precipitate out, collect the precipitate, and degrease the precipitate with ether. Add 0.2L of 10% sodium hydroxide solution to the precipitate after degreasing, then add 0.5L of ethanol, stir to dissolve, filter, take the filtrate, adjust the pH to 6-7 with glacial acetic acid, precipitate the precipitate, filter with suction, and filter the cake with 50 % (v / v) ethanol and distilled water are fully washed, dried and pulverized to obtain acaciacin-7-O-rhamnoglucoside with a content of 94.2% (W / W).
