Embodiment 1
[0027] The preparation of embodiment 1 Chinese medicine compound total extract
[0028] The two medicines of Ligustrum lucidum, Atractylodes macrocephala, Eucommia ulmoides, Panax notoginseng, Daji, Salvia miltiorrhiza, Coptis chinensis, and Bergamot (weight ratio 2:1:1:1:1:2:1:1) Crushed into coarse powder, reflux extraction with 60% ethanol of 10 times, 8 times and 6 times the amount of the medicinal material respectively, 2 h each time, combine the extracts, recover the ethanol and make the concentration of the alcohol extraction part equal to 1 ml 1 g crude drug; the rest of the medicinal materials in the prescription were decocted and extracted 3 times with 12 times, 10 times and 8 times the amount of water respectively, each time for 2 hours, combined 3 times of water extracts, and concentrated under vacuum to 1 g medicinal materials / ml extract solution, the water body part and the previous alcohol extraction part were combined to obtain the total extract of the tradi...
Embodiment 2
[0029] Example 2 Preparation of Petroleum Ether Extraction Parts of Compound Total Extract
[0030] Extract once with petroleum ether of 10 times the volume of the total compound extract, and separate the petroleum ether layer; then extract once each with 8 and 6 times the volume of petroleum ether, separate and obtain the petroleum ether layer, combine the petroleum ether extracts for 3 times, and recover Petroleum ether, then vacuum-dried at 0.08MPa and 65°C to obtain petroleum ether extract (FTZEE);
[0031] The yield of the extract was calculated according to the total dosage of the compound Chinese medicine and the amount of the extracted part. The yield of petroleum ether extract is 0.3%-0.5% (3.0-5.0g of petroleum ether extract is obtained from 1kg crude drug).
Embodiment 3
[0032] Example 3 Chemical Composition Analysis of the Petroleum Ether Extraction Part of the Compound Total Extract
[0033] Embodiment 2 compound petroleum ether extract (FTZEE), through HPLC analysis, obtains figure 1 sample fingerprint.
[0034] UPLC chromatographic conditions for FTZ petroleum ether fraction: Agilent HC-C 18 Chromatographic column (4.6mm×250mm, 1μm), guard column phenomenonex KJO-4282-C 18 Column; mobile phase using acetonitrile (A) - water (containing 0.25% glacial acetic acid + 0.13% triethylamine) (B) binary gradient system. Gradient elution: 2~5% A (0~5 min), 5%~20% A (5~35 min), 20% A (35~45 min), 20%~35% A (45~70 min ), 35%~80%A (70~85 min), 80%~100%A (85~87 min), 100%A (87~89 min). The detection wavelengths were 254 nm, 300 nm and 330 nm, the column temperature was 30 °C, the flow rate was 0.2 mL / min, and the injection volume was 10 μL.
[0035] Qualitative analysis results: FTZ petroleum ether mainly contains waxy alcohol, β-sitosterol, n-he...
