Embodiment 1

[0036] Example 1: Take the leaves of Shanxiangyuan, add water and decoct 2 times, the first time is 30 times the amount for 2 hours, and the second time is 25 times the amount for 1.5 hours. Combine the decoction and concentrate under reduced pressure to a relative density of 1.08~1.18 (80 ℃ heat test) the clear paste, add ethanol to 75% alcohol content, stir, let stand for 24 hours, filter, the filtrate recovers the ethanol, concentrated under reduced pressure to 1:0.8 ~ 1.6 (W / V), diluted with water 3 times the amount of medicinal materials (V / W), adjust the pH to 4 by dilute hydrochloric acid, slowly pass (about 1BV / hr) 2 times the amount of medicinal materials (W / W) processed AB-8 macroporous adsorption resin column , Water eluted 3BV (about 2BV / hr), 15% ethanol eluted 3BV (about 2BV / hr), 65% ethanol eluted, collected 65% ethanol eluate, recovered ethanol, concentrated under reduced pressure, spray-dried to obtain The extract from the leaves of Serratia vulgaris, the yield is ...

Embodiment 2

[0058] Example 2: Same as Example 1 by boiling and alcohol precipitation process to obtain the extract, slowly passing (about 1BV / hr) 2 times the amount of medicinal material (W / W) processed polyamide column, water elution 4BV( Approximately 2BV / hr), eluted with 95% ethanol, collected the eluate, recovered the ethanol, concentrated under reduced pressure, and spray-dried to obtain the sagebrush leaf extract with a yield of about 3.4%.

Embodiment 3

[0059] Example 3: Same as Example 1 by boiling and alcohol precipitation process to obtain the extract, adjust the pH to 4 with dilute hydrochloric acid, extract 4 times with water-saturated n-butanol, combine the extracts, recover the n-butanol under reduced pressure, concentrate, and spray Dry it and get it; or mix the n-butanol extraction concentrate with an appropriate amount of diatomaceous earth, dry it, add ethanol to extract twice, combine the ethanol extracts, recover the ethanol, concentrate under reduced pressure, and spray dry to get it. The yield is about It is 2.6~3.6%.

[0060] 1. Determination of total phenolic acid content:
