Embodiment 1
[0041] Example 1: Preparation of Qizhi Tongluo Capsules.
[0042] Prescription: Astragalus 325g, Leech 130g, Ginseng 130g, Ophiopogon japonicus 32.5g, Schisandra chinensis 65g, Angelica 65g, Chuanxiong 65g, Maodongqing 325g, Radix Paeoniae Rubra 65g, Spatholobus 65g, Salvia miltiorrhiza 65g, Polygonum multiflorum 162.5g, Safflower 32.5g , Zeilan 32.5g, Eucalyptus 32.5g, Dilong 32.5g, Silkworm 6.5g, Curcuma 65g, Turmeric 32.5g, Scorpion 13g, Gastrodia elata 13g, Cinnamon 13g, Notopterygium 32.5g, Pig tooth soap 6.5g, Dannanxing 13g, borneol 13g.
[0043] Preparation method: the above twenty-six flavors, except borneol, leech, ground beetle, cinnamon, scorpion, stiff silkworm, and Dannanxing, are crushed into fine powder, sieved, and mixed; Add 10 times the amount of water for the first time, add 5 times the amount of water for the second time, decoct for 2 hours each time, collect the volatile oil at the same time during the decoction process, and use the β-cyclodextrin to cov...
Embodiment 2
[0049] Example 2: TLC identification of leeches.
[0050] Take 5 g of the drug content of Example 1, add 3 g of diatomaceous earth, mix well, add 30 ml of methanol, ultrasonically treat for 20 minutes, filter, evaporate the filtrate to dryness in a water bath, add 30 ml of water to the residue to dissolve, shake and extract 3 times with ether, 20ml each time, the aqueous solution is for later use, the ether extracts are combined, the ether is evaporated, and the residue is dissolved by adding 1ml of methanol, which is used as the test solution. Take another 1.5 g of leech reference drug, add 10 ml of methanol, sonicate for 20 minutes, filter, and concentrate the filtrate to about 1 ml, as the reference drug solution. According to the thin-layer chromatography (Appendix VI B of "Chinese Pharmacopoeia" 2010 edition), draw 3 μl of the test solution and 2 μl of the reference medicinal material solution, respectively spot on the same silica gel G thin-layer plate, and use chlorofor...
Embodiment 3
[0051] Example 3: TLC identification of Radix Paeoniae Rubra.
[0052]Get the aqueous solution after diethyl ether extraction in Example 2, shake and extract 3 times with water-saturated n-butanol (20ml, 10ml, 10ml), combine the n-butanol extract, extract 3 times with ammonia test solution, each 15ml, discard Remove the ammonia solution, evaporate the n-butanol solution to dryness, add 3ml of water to the residue to dissolve, put it on a D101 macroporous adsorption resin column (inner diameter 2cm, length 12cm), elute with 50ml of water, discard the water, and then use 40% Elute with 30ml of ethanol, discard the 40% ethanol eluate, continue to elute with 50ml of 70% ethanol, collect the eluate, evaporate to dryness, add 1ml of methanol to the residue to dissolve, and use it as the test solution. Take another paeoniflorin reference substance, add ethanol to make a solution containing 2mg per 1ml, as the reference substance solution. According to the thin-layer chromatography (...
