Embodiment 1
[0043] An anti-allergic compound flavonoid composition is prepared from the following Chinese medicinal materials in parts by weight: 40 parts by weight of licorice, 25 parts by chamomile, and 15 parts by weight.
[0044] The preparation method is as follows:
[0045] (1) Powdering: Glycyrrhizae, chamomile and Fangfeng are pulverized, then mixed evenly to obtain medicinal powder;
[0046] (2) Extraction: Add pure water 6 times its total weight to the medicinal powder, stir evenly, place in a low-temperature and high-pressure differential extractor, extract at -0.1MPa, 0°C, collect the extract for centrifugation, and collect Centrate;
[0047] (3) Separation and concentration: Use a 0.2 μm microfiltration membrane to remove impurities such as solid particles and bacteria, and then use a 100 Da flux ultrafiltration membrane for fractional purification, and the obtained retentate is concentrated to a specific gravity of 1.50.
[0048] The licorice of this embodiment: chamomile:...
