Embodiment Construction

[0018] Below in conjunction with embodiment the present invention is described further, but the present invention is not limited to these embodiments, under the premise of not departing from the gist of the present invention, any improvement done all falls within the protection scope of the present invention.

[0019] Safflower yellow pigment extraction process, the steps are as follows:

[0020] 1. Medicinal material extraction: Take the safflower medicinal material, add water 8-10 times the weight of the medicinal material, stir and extract twice at 69-71°C, each time for 1-1.5 hours, filter, combine the two extracts, and cool to room temperature.

[0021] 2. Adsorption on a macroporous adsorption resin column. According to the ratio of 1:5 (W:V) between the amount of sample on the column and the amount of resin, add it to the macroporous adsorption resin column at a flow rate of 2-2.5bV / h for adsorption.

[0022] 3. For the first elution, use 50% (volume percent) ethanol as...

Abstract

The invention discloses an extraction process of medicinal components of a Chinese herbal medicine safflower and particularly relates to an extraction process of carthamin yellow. The extraction process comprises the following steps: extraction of medicinal materials, adsorption by virtue of a macroporous adsorption resin column, primary elution, adsorption by virtue of a polyamide column, secondary elution, concentration and spray-drying. The extraction process of carthamin yellow can be used for effectively solving the disadvantages existing in the prior art of the background technology, the yield of the extracted carthamin yellow is not less than 2%, hydroxyl safflower flavin A contained in the carthamin yellow is not less than 20%, and general flavone contained in the carthamin yellow is not less than 80%.

Description

technical field [0001] The invention discloses a process for extracting medicinal components of safflower, a traditional Chinese medicinal material, and in particular relates to a process for extracting safflower yellow pigment. Background technique [0002] Safflower yellow pigment, functions mainly for promoting blood circulation and removing blood stasis, dredging channels and relieving pain. It is used for stable exertional angina pectoris of grade I, II, and III caused by heart-blood stasis. [0003] At present, there are extensive reports on the extraction process of safflower yellow, but there are generally problems such as long time-consuming extraction process, high energy consumption, and low yield. Contents of the invention [0004] In order to solve the above-mentioned technical problems, the object of the present invention is to provide a process for extracting safflower yellow pigment, which can effectively solve the above-mentioned problems, and has high yie...
