Embodiment 1

[0072] Preparation of the extract from the antihypertensive effective part of Hebei Fragrant Chrysanthemum

[0073] (1) Hebei Xiangchrysanthemum was extracted twice by reflux with 70% ethanol, the filtrates were combined and concentrated under reduced pressure to obtain a chrysanthemum extract, which was set aside.

[0074] (2) Resin pretreatment: D-101 type macroporous resin was soaked in 95% ethanol for 24 hours, rinsed with 95% ethanol until the ethanol was colorless and transparent, collected the last 50ml, evaporated to dryness, no white powdery matter. Rinse with 5% sodium hydroxide 2 times the volume of the resin bed, rinse with distilled water until neutral, then rinse with 5% HCl solution 2 times the volume of the resin bed, rinse with distilled water until neutral.

[0075] (3) According to the loading amount of chrysanthemum extract (converted to the amount of crude drug): resin=1:2~1:4, put the chrysanthemum extract on the column, control the flow rate of the efflu...

Embodiment 2

[0078] Preparation of Hebei Fragrant Chrysanthemum ≤ 60% Ethanol Eluted Extract

[0079] (1) Hebei Fragrant Chrysanthemum (purchased from Shijiazhuang Fragrant Chrysanthemum Technology Development Co., Ltd.) was refluxed twice with 70% ethanol, and the filtrates were combined and concentrated under reduced pressure to obtain a chrysanthemum extract, which was set aside.

[0080] (2) Resin pretreatment: HPD-600 macroporous resin was soaked in 90% ethanol for 24 hours, rinsed with 95% ethanol until the ethanol was colorless and transparent, collected the last 50ml, evaporated to dryness, no white powdery matter. Rinse with 5% sodium hydroxide 2 times the volume of the resin bed, rinse with distilled water until neutral, then rinse with 5% HCl solution 2 times the volume of the resin bed, rinse with distilled water until neutral.

[0081] (3) According to the loading amount of chrysanthemum extract (converted to the amount of crude drug): resin = 1:3, put the chrysanthemum extrac...

Embodiment 3

[0084] Antihypertensive Tablets Prepared by Hebei Fragrant Chrysanthemum Antihypertensive Effective Fraction Extract as Active Ingredient

[0085] 2000 kg of ≤ 40% ethanol eluted extract prepared by the method of Example 1, according to the conventional tablet preparation method, add starch, dextrin, magnesium stearate, etc., mix to make wet granules, and machine stamped into tablets, each tablet Contains 10mg of total flavonoids.

Abstract

The invention relates to the depressurization active part extracts of Hebei chrysanthemum, the preparing method and its application in the medical preparation is also mentioned in the invention. The extract is obtained through adsorbing the extracted solution by macroporous resin and eluting by alcohol (less than 60%). The preparing procedure includes the following steps: getting the extracted solution from Hebei chrysanthemum with routine method; adsorbing and eluting the solution, the eluting solution is alcohol (the density of which is smaller than 60%); collecting the eluted solution; condensing and drying. The extract can be used as the active ingredient to prepare different kinds of pharmaceutical dosage forms such as soft capsule, pellet, dripping pills, injectable preparation and slowly controlled releasing dosage. The invention has provided a new and steady hypotensive drug for clinical use.

Description

technical field [0001] The present invention relates to medicinal active ingredients of plants and its extraction and preparation method and application, in particular to the extract of chrysanthemum antihypertensive effective parts, its separation and extraction method and its application in pharmaceutical preparations. Background technique [0002] Chrysanthemum (Chrysanthemum morifolium Ramat.) is the inflorescence head of Chrysanthemum chrysanthemum, which has the functions of dispelling wind, clearing heat, improving eyesight and detoxifying. Clinically, it is mainly used to treat headache, dizziness, red eyes, dysphoria in the heart and chest, boils, and swelling. Studies have shown that chrysanthemum contains multiple medicinal active ingredients, and it is generally believed that flavonoids, triterpenoids, and volatile oil are its main active ingredients. Pharmacological experiments show that the total extract of chrysanthemum has a positive effect on the prevention...
