example 1
[0063] The preparation method of example one composition of the present invention
[0064]
[0065] For the above six flavors, take purple rhododendron, kansui, and genkwa, use 8 times the amount of 65% ethanol to reflux extract twice, each time for 2 hours, filter, combine the filtrate, recover ethanol, concentrate to a relative density of 1.30~ when measured at 60 ° C 1.35 thick paste, dried and crushed to obtain ethanol extract, set aside; take Codonopsis pilosula, Pinellia chinensis, and alum, decoct twice with 8 times the amount of water for 2 hours each time, filter, combine filtrates, and concentrate to 60°C When measuring the thick paste with a relative density of 1.30-1.35, dry, pulverize, and obtain a water extract for later use; add the fine powder of the above-mentioned extract into a hot-melted 2-fold amount of polyethylene glycol 6000 matrix, stir and mix evenly, and transfer Put it on the dripping pill device, keep it sealed at 80-90°C, drop it into the cond...
example 2
[0066] The thin layer identification method of example two compositions of the present invention
[0067] a. Take 6g of this product, grind it finely, add 40ml of ethanol, heat and reflux for 1 hour, filter, evaporate the filtrate to dryness, add 25ml of water to the residue to dissolve, shake and extract 3 times with ethyl acetate, 25ml each time, combine ethyl acetate solution, add water to wash 2 times, 25ml each time, discard the water solution, evaporate the ethyl acetate solution to dryness, add 1ml of methanol to the residue to dissolve, and use it as the test solution; take 1g of Daphne genkwa as a reference drug, and prepare the reference drug solution in the same way ; Take 4 μl of each of the above two solutions, spot them on the same silica gel G thin-layer plate, use chloroform-ethyl acetate-formic acid = 20:5:1 as the developer, develop, take out, dry in the air, and spray with 5 % aluminum chloride ethanol solution, blown with hot air until the spots are clear...
example 3
[0071] The assay method of example three compositions of the present invention
[0072] Quercetin was determined according to high-performance liquid chromatography (Chinese Pharmacopoeia 2015 Edition Sibu General Rules 0512).
[0073] Chromatographic conditions and system suitability test: Octadecylsilane bonded silica gel is used as filler; methanol-0.4% phosphoric acid solution = 49:51 is used as mobile phase; detection wavelength is 370nm; the number of theoretical plates should be calculated according to the peak of quercetin No less than 4000.
[0074] Preparation of reference substance solution Take an appropriate amount of quercetin reference substance, weigh it accurately, add methanol to make a solution containing 15 μg per 1 ml, and obtain it.
[0075]Preparation of the test solution Take this product, grind it finely, take about 1.0g, accurately weigh it, put it in a stoppered Erlenmeyer flask, add 25ml of 80% methanol precisely, seal it tightly, weigh it, heat ...
