Embodiment 1
[0024] Example 1 Extraction Solvent Selection
[0025] Take a meat cardamom, 400g of the ginger, 150g of Atractylodes, 150g of the sheon, 150g of wood, add 70% ethanol reflux, 2 hours each time, each time the ethanol is 10 times, two times The extract was extracted and concentrated into the nano, then water saturated n-butanol, ethyl acetate, petroleum ether (60-90 ° C) was added three times, and the extraction liquid was recovered and concentrated to a relative density of 1.32 (60). Eligand, spare of ° C).
[0026] Control: 400g of meat, 400g of gun ginger, 150g of Atractylodes, 150g of abuts, 150g of wood, plus 70% ethanol reflux, each time 2 hours, each time the amount of ethanol is 10 times, combined The extract was extracted and concentrated to a thick paste of a relative density of 1.32 (60 ° C), spare.
[0027] The above four samples were sampled, respectively, HPLC chromatography assays the content of hydrogen diisobutylol and 6-ginger plexus.
[0028] The chromatographic ...
Embodiment 2
[0035] Nutmeg 400g gun ginger 400g Atractylodes 150g
[0036] Amount 150g woody 150g in vitro cultivating cattle yellow.
[0037] 1) Take a meat cardamom, artillery, atractylodes, abuts, wood, add water, soaked, water volatile oil, spare; spare; 70% ethanol reflux for 2 hours, each time 2 hours, each time ethanol The amount is 10 times the weight of the drug, and the extract is combined and concentrated to the nano, then ethyl acetate is added three times, and the extract is recovered to ethyl acetate and concentrated to a relative density of 1.32 (60 ° C). Cream, spare.
[0038] 2) Mix the grungy, volatile oil, and in vitro of the bovine yellow powder and the 550 g of the matrix, then apply it to the leak-proof of the umbilical paste, cool the back to the anti-stick layer. The matrix consists of the following weight ratio: 38.5% of Vaseline, 30% of lamb fat, 20% paraffin, 10% glycerin, and 1.5% of the laurel nitride, and heat melt together.
