Embodiment 1
[0027]The flowers and buds of Lonicerae pilosula are extracted with 8 times the volume of 60% ethanol at 90 degrees Celsius, and the solvent is recovered to one-fifth of the original volume of the extract, cooled to 0 degrees Celsius, filtered to obtain the filtrate, and the filtrate is added 8% KOH was hydrolyzed at 80 degrees Celsius for 10 hours, extracted with n-butanol after cooling, and the n-butanol extract was back-extracted with an alkaline aqueous solution with a pH value of 13 saturated with n-butanol, and the n-butanol solution after back extraction was adjusted to pH The value is 7, and the n-butanol solution is reclaimed to obtain the Flos Lonicerae extract, after testing, by weight, wherein Lonicera tomentosa saponin B (hereinafter referred to as component a): Lonicera tomentosa saponin A (hereinafter referred to as group Part b): 3-O-α-L-rhamnopyranosyl (1-2)-α-L-arabinopyranosyl-hederidenin (hereinafter referred to as component c): 3-O- β-D-glucopyranosyl(1-4)...
Embodiment 2
[0029] Red gland honeysuckle flower and flower buds, use 10 times the volume of water, extract at 60 degrees Celsius, recover the solvent to one-sixth of the original volume of the extract, cool to 2 degrees Celsius, filter to obtain the filtrate, add 50% NaOH to the filtrate, and add 50% NaOH to the filtrate. It was hydrolyzed for 3 hours under Celsius, extracted with n-butanol after cooling, and the n-butanol extract was back-extracted with 0.1% NaOH aqueous solution saturated with n-butanol, and the pH value of the n-butanol solution after the back extraction was adjusted to 7, and the n-butanol solution was recovered. The butanol solution obtains the Flos Japonica extract, and after testing, by weight, component a: component b: component c: component d=42:9:10:1, and the total weight of the four ingredients It accounts for 62% of the extract, and the yield is 12%.
Embodiment 3
[0031] The red glandular honeysuckle flower and flower buds and the yellow-brown honeysuckle flower and flower buds with a weight ratio of 1:1 are extracted at normal temperature with 100% methanol at a concentration of 3 times the volume, and the extract is recovered to a quarter of the original volume. Cool down to 4 degrees Celsius, filter to obtain the filtrate, add 0.5% KOH to the filtrate, hydrolyze it at 40 degrees Celsius for 10 hours, extract it with n-butanol, and extract the n-butanol extract with 0.8% KOH saturated with n-butanol. The final n-butanol solution adjusts the pH value to 7, reclaims the n-butanol solution and obtains the Flos Japonica extract, after testing, by weight, component a: component b: component c: component d=14:2:3:1 , and the total weight of the four components accounts for 74% of the extract, with a yield of 11%.
[0032] First mix 120 g of polyethylene glycol and 30 g of lactose, then add 300 g of the above-mentioned extract and mix evenly...
