[0034] Example 2 Preparation of Bufei Huoxue Capsule Extract of the present invention and content of active substances
[0035] The preparation of Bufei Huoxue capsule of the present invention:
[0036] Take the astragalus slices, red peony root and psoralen of the raw material formula of the composition 4 of Example 1 and grind them into coarse powder, reflux extraction with 60%-70% ethanol alcohol twice, add 5 amounts of 60%-70% ethanol for the first time, Extract for 2 hours, 4 times the amount of 60%-70% ethanol for the second time, extract for 1 hour, combine the two extracts, filter, recover the filtrate under reduced pressure until it has no alcohol smell, continue to concentrate under reduced pressure to a relative density of 1.30-1.40 Clear ointment, that is to say.
[0037] The Bufei Huoxue capsule extract contains the following active substances: astragaloside IV, paeoniflorin, psoralen and isopsoralen, the results are shown in Table 1, and the assay method is in...

[0044] Example 3 Preparation of Bufei Huoxue Capsule Extract of the present invention and content of active substances
[0045] In this experiment, supercritical CO 2 The process parameters of the extraction equipment were comprehensively studied to find the influence of various extraction conditions (extraction temperature, pressure, entrainer and time) on the extraction amount and effective substance content. After investigation, the ethanol concentration of the entrainer had little effect (the ethanol concentration was 70% ~90%, 80% is better), extraction pressure, extraction temperature, extraction time and entrainer are the main influencing factors, so the yield of astragaloside IV and extract is used as index to investigate the effect of four factors on The effect of the extraction effect. See Table 3 for the factors and levels of investigation.
