Embodiment 1

[0021] Example 1 The Extraction and Separation of Suspended Begonia Flower Extract and Active Compounds

[0022] A preparation method for the extract of the crabapple, which uses the flower of the crabapple as a raw material, soaks the flower of the crabapple dried in the shade with 70V% ethanol for 3 times, 3 days each time, and combines the extracts, filters, and concentrates to obtain the crabapple Begonia flower total extract. Take a part of the total extract of Begonia chinensis, dissolve it in methanol, separate it by D-101 macroporous resin column chromatography, and elute it with water, 20V% methanol, 40V% methanol, 60V% methanol, methanol gradient, and each concentration gradient elution 5 column volumes, each with a volume of 2000mL, were concentrated to obtain water part extract, 20% methanol part extract, 40% methanol part extract, 60% methanol part extract, and methanol part extract respectively.

Abstract

The invention belongs to the technical field of plant extracting, particularly relates to a filamental flowering crab extract comprising filamental flowering crab total extract, 40% of methyl alcohol part extract, 60% of methyl alcohol part extract and methyl alcohol part extract, as well as preparing and application of an active compound baohuoside II (1), kaempferol-3-O-alpha-L-furanoarabinoside (2), phloretin-4'-O-heteroside (3) and kaempferol-3-O-alpha-L-rhamnoside (4) separated from the filamental flowering crab. An experiment proves that each extract and each active compound of the filamental flowering crab have an anticoagulation action, and can be used for preparing anticoagulant singly or in a combining manner.

Description

technical field [0001] The invention belongs to the technical field of medicine and / or health care products, and specifically relates to an extract of crabapple, an active compound isolated from the flower of crabapple, a preparation method, and its new application in anticoagulation. Background technique [0002] Malushalliana Koehne (Malushalliana Koehne) is a plant of the genus Apple in the Rosaceae family. Chuisi crabapple has slight gas, slightly bitter and astringent taste, flat nature, belongs to the liver meridian, has the effect of regulating menstruation and blood, and is mainly used to treat metrorrhagia. Suisi Begonia, together with C.speciosa, Xifu Begonia (M.micromalus) and Papaya Begonia (C. cathayensis) of the same family, is called "Four Begonias". After reviewing the literature, it was found that: the crabapple has the functions of protecting the liver, anti-oxidation, and inhibiting the activity of α-glucosidase in vitro, and there are certain active ingr...
