Embodiment 1

[0023] Example 1: The amount of anemarrhena medicinal material is 0.05 times of the weight of Fructus Citrus Aurantium

[0024] Take 10kg Citrus aurantium medicinal material and 0.5kg Anemarrhena medicinal material and mix and pulverize; extract with 75% ethanol aqueous solution under heat reflux for 3 times, extract with 50L for 3 hours for the first time, and extract with 30L for 2 hours for the second and third times; extract the obtained Concentrate the liquid until it has no alcohol smell, enrich it with D101 macroporous resin, first remove impurities with 35% ethanol, and elute until the eluent is colorless, then enrich the active part with 70% ethanol, and elute until the eluent is colorless. The 70% ethanol eluate was concentrated and spray-dried.

Embodiment 2

[0025] Example 2: The amount of Zhimu medicinal material is 0.06 times the weight of Fructus Aurantii

[0026] Take 10kg Citrus aurantium medicinal material and 0.6kg Anemarrhena medicinal material and mix and pulverize; extract with 75% ethanol aqueous solution under heat reflux for 3 times, extract with 50L for 3 hours for the first time, and extract with 30L for 2 hours for the second and third times; extract the obtained Concentrate the liquid until it has no alcohol smell, enrich it with D101 macroporous resin, first remove impurities with 35% ethanol, and elute until the eluent is colorless, then enrich the active part with 70% ethanol, and elute until the eluent is colorless. The 70% ethanol eluate was concentrated and spray-dried.

Embodiment 3

[0027] Example 3: The amount of Zhimu medicinal material is 0.08 times the weight of Citrus aurantium

[0028] Take 10kg Citrus aurantii medicinal material and 0.8kg Anemarrhena anemarrhena medicinal material, mix and pulverize; extract with 75% ethanol aqueous solution under heat reflux for 3 times, extract with 50L for 3 hours for the first time, and extract with 30L for 2 hours for the second and third times; extract the obtained Concentrate the liquid until it has no alcohol smell, enrich it with D101 macroporous resin, first remove impurities with 35% ethanol, and elute until the eluent is colorless, then enrich the active part with 70% ethanol, and elute until the eluent is colorless. The 70% ethanol eluate was concentrated and spray-dried.

Abstract

The invention discloses an immature bitter orange extract, a preparation and an application, belongs to the field of a traditional Chinese medicine, and particularly relates to an immature bitter orange extract and a medicinal preparation containing the extract. The immature bitter orange extract can be used for preparing a medicine for preventing or treating obesity. The immature bitter orange extract, which is obtained by adding a small amount of rhizoma anemarrhenae medicinal material into an immature bitter orange medicinal material, has a significant effect of treating the obesity, and has an unexpected effect in comparison with a single immature bitter orange extracting method. Based on the sufficient and reasonable design, the immature bitter orange extract with a significant effect can be obtained by extracting, denominating and enriching ethanol water with proper concentration.

Description
