Embodiment 1

[0029] Embodiment 1: Get the round leaves of Cymbidium chinensis, add water and decoct 2 times, the first time 16 times the amount for 2 hours, the second time 14 times the amount for 1.5 hours, combine the decoction liquid, concentrate under reduced pressure until the relative density is 1.08~1.18 (80 ℃ heat measurement), add ethanol until the alcohol content is 75%, stir, let stand for 24 hours, filter, recover ethanol from the filtrate, concentrate under reduced pressure to 1:0.8~1.6 (W / V), add water to dilute to 3 times the amount of medicinal materials (V / W), dilute hydrochloric acid to adjust the pH value to 4, and slowly pass through (about 1BV / hr) 2 times the amount of medicinal materials (W / W) AB-8 macroporous adsorption resin column that has been treated , water elutes 3BV (about 2BV / hr), 15% ethanol elutes 3BV (about 2BV / hr), 65% ethanol elutes, collects 65% ethanol eluate, reclaims ethanol, concentrates under reduced pressure, and spray-dries to obtain The extract ...

Embodiment 2

[0047] Embodiment 2: With the process of water boiling and alcohol precipitation in Example 1, the extract is obtained, and slowly passes through (about 1BV / hr) 2 times the treated polyamide column of the medicinal material amount (W / W), and water elutes 4BV ( about 2BV / hr), eluted with 95% ethanol, collected the eluate, recovered ethanol, concentrated under reduced pressure, and spray-dried to obtain the extract of Cymbidium rotifera, with a yield of about 3.4%.

Embodiment 3

[0048] Example 3: The same process as in Example 1 was boiled and alcoholized to obtain the extract, the pH value was adjusted to 4 with dilute hydrochloric acid, extracted 4 times with water-saturated n-butanol, the extracts were combined, the n-butanol was recovered under reduced pressure, concentrated, and sprayed Dry it to get it; or mix the n-butanol extraction concentrate with an appropriate amount of diatomaceous earth, dry it in the air, add ethanol to extract twice, combine the ethanol extract, recover ethanol, concentrate under reduced pressure, and spray dry to get it. The yield is 3.6%.

[0049] 1. Determination of total phenolic acid content:

[0050] Determination according to ultraviolet-visible spectrophotometry (Appendix V A of Chinese Pharmacopoeia 2005 edition).

[0051] Preparation of reference substance solution Accurately weigh gallic acid reference substance, add absolute ethanol to make a solution containing 20μg per 1ml, and set aside.
