Embodiment 1
[0029] Preparation of total flavonoid carbon glycosides extract from Jigucao
[0030] Take 1Kg of chicken bone herbal medicine, add 70% ethanol to reflux and extract twice, combine the alcohol extracts, recover under reduced pressure until there is no alcohol smell, centrifuge, and put the supernatant on the treated D101 macroporous adsorption resin column after adsorption , followed by elution with 3 liters of deionized water and 5 liters of 50% ethanol, collecting the 50% ethanol eluate, and evaporating to dryness under reduced pressure to obtain 21 g of total flavonoid glycosides extract of Chickweed. Using HPLC-UV method for quantitative analysis, apigenin-6,8-diC-glucoside, apigenin-6-C-glucose-8-C-arabinoside and apigenin-6-C-arabinose-8- The contents of C-glucoside were 17.0%, 15.1%, and 19.6%, respectively.
Embodiment 2
[0032] Preparation of total flavonoid carbon glycosides extract from Jigucao
[0033] Add 10 times the amount of 95% ethanol to the extract obtained in Example 1, heat and reflux for extraction for 1 hour, and suction filter while it is hot. The filtrate is recovered from ethanol and then vacuum-dried to obtain a high-purity total flavonoid glycosides extract of Chickweed. Using HPLC-UV method for quantitative analysis, apigenin-6,8-diC-glucoside, apigenin-6-C-glucose-8-C-arabinoside and apigenin-6-C-arabinose-8- The contents of C-glucoside were 20.0%, 17.5%, and 25.6%, respectively.
Embodiment 3
[0035] Preparation of total flavonoid carbon glycosides extract from Jigucao
[0036] Add 10 times the amount of 75% ethanol to the extract obtained in Example 1, heat and reflux for extraction for 1 hour, and suction filter while it is hot. The filtrate is recovered from ethanol and then vacuum-dried to obtain a high-purity total flavonoid glycosides extract of Chickweed. Using HPLC-UV method for quantitative analysis, apigenin-6,8-diC-glucoside, apigenin-6-C-glucose-8-C-arabinoside and apigenin-6-C-arabinose-8- The contents of C-glucoside were 22.0%, 15.5%, and 24.3%, respectively.
