Embodiment 1

[0016] Embodiment 1: Preparation of total paeony glucosides

[0017] Take 20kg of paeonol medicinal material (place of origin: Tongling), crush it into coarse powder, put it into an extraction tank; add 200L of water and boil it for 2 times, each time for 2h, after filtering, concentrate under reduced pressure to about 30L; use AB-8 type Macroporous adsorption resin column, fully eluted with water until the effluent was clear and free of reducing sugar reaction, then eluted with 40% ethanol; collected eluate, concentrated under reduced pressure, extracted twice with chloroform, recovered chloroform, and added 95% % ethanol to make the alcohol concentration 80%. Let it stand for 0.5h, filter off the precipitate, and recover the filtrate to dryness under reduced pressure to obtain 1 kg of paeonol glycosides raw material. The content of total glycosides in the total glycosides of paeony in the effective part was detected by HPLC to be 66%, and the content of paeoniflorin as the ...

Embodiment 2

[0018] Embodiment 2: Preparation of total paeony glycosides freeze-dried powder injection

[0019] Under clean conditions, take 50g of refined total paeony glycosides, add appropriate amount of water for injection to dissolve, stir to dissolve, and ultra-filter to obtain a pyrogen-free clear liquid, add water for injection to 1000ml, subpackage into 1000 tubes, press freeze-dried powder injection The process is freeze-dried to make a freeze-dried powder containing 50 mg of total paeony glycosides.

Embodiment 3

[0020] Embodiment 3: preparation paeony total glucosides capsule

[0021] Take 100g of the above-mentioned total paeonol glycosides raw material, 50g of starch, and 100g of β-cyclodextrin, mix evenly, granulate, sieve, dry and pack into 1000 capsules (100mg / capsule).

Description

technical field [0001] The invention relates to an extract of total paeony glycosides and a preparation method thereof, as well as the application of the total paeony glycosides extract in the preparation of medicines for treating or preventing cardiovascular and cerebrovascular diseases. Background technique [0002] Cortex Moutan, also known as Cortex Moutan, Bark Fen, Paeoniae Alba, Cortex Tiaodan, and Luoyang Flower, is the root bark of Paeoniae genus Paeoniae in the family Ranunculaceae. It is used for warm-toxin-induced spots, vomiting, bleeds, blood in the stool, bone steaming and labor-heat, amenorrhea dysmenorrhea, carbuncle sores, and pain caused by tumbling. Cortex Moutan contains paeoniflorin, benzoylpaeoniflorin, paeonol glycoside, paeonol protoside, paeonol, benzoic acid, volatile oil, sugar and sterol and other ingredients. Studies have found that paeoniflorin has pharmacological effects such as expanding coronary arteries, increasing coronary flow, resisting...
