Embodiment 1

[0022] A method for preparing effective parts of apple blossoms includes the following steps: 1 kg of dried apple blossoms are used as raw materials, and after crushing, 65% ethanol (65% ethanol is 8L) is added, and heated and extracted 3 times, each time After 1 h, the extracts were combined and concentrated to obtain the total extract; the total extract was dispersed in water, extracted with petroleum ether, ethyl acetate, and n-butanol in turn, and the dry solvent was evaporated to obtain the ethyl acetate extract, namely apple Flower effective parts.

[0023] The method for extracting kaempferol glucoside from the effective parts of apple blossoms includes the following steps: dissolving the effective parts of apple blossoms in water, loading the sample on a macroporous resin column, and eluting with 30% ethanol and 60% ethanol in sequence to obtain the corresponding elution Part; Select the 60% ethanol elution part to pass through the silica gel H normal pressure chromatogra...

Embodiment 2

[0027] A method for preparing effective parts of apple blossoms includes the following steps: 1kg of dried apple blossoms are used as raw materials, after crushing, 70% ethanol (70% ethanol consumption is 8L) is added, heating and extracting 3 times, each time After 0.5 h, the extracts were combined and concentrated to obtain the total extract; the total extract was dispersed in water, extracted with petroleum ether, ethyl acetate, and n-butanol in turn, and the dry solvent was evaporated to obtain the ethyl acetate extract, namely apple Flower effective parts.

[0028] The method for extracting kaempferol glucoside from the effective parts of apple blossoms includes the following steps: dissolving the effective parts of apple blossoms in water, loading the sample on a macroporous resin column, and eluting with 30% ethanol and 60% ethanol in sequence to obtain the corresponding elution Part; Select the 60% ethanol elution part to pass through the silica gel H normal pressure chro...

Embodiment 3

[0031] A method for preparing effective parts of apple blossoms includes the following steps: 1kg of dried apple blossoms are used as raw materials, and after crushing, 80% ethanol (80% ethanol is 8L) is added, and heated and extracted twice, each time After 2 h, the extracts were combined and concentrated to obtain the total extract; the total extract was dispersed in water, and then extracted with petroleum ether, ethyl acetate, n-butanol, and the dry solvent was evaporated to obtain the ethyl acetate extract, namely apple Flower effective parts.

Abstract

The invention discloses a preparation method of an apple flower effective part, wherein the preparation method comprises the following steps: crushing apple flowers, carrying out heating extraction with ethanol, concentrating the extract liquid, then dispersing in water, and successively extracting with petroleum ether, ethyl acetate and n-butanol, to obtain an ethyl acetate extract. The inventionalso discloses a method for extracting kaempferol glucoside from the apple flower effective part; the apple flower effective part is treated by a silica gel column, a gel column, a preparative high performance liquid phase and other separation methods. The invention provides the method for extracting and separating kaempferol glucoside from the apple flowers, better development and utilization ofthe medicinal plant of the apple flowers are facilitated, kaempferol glucoside is studied deeply, the time and the labor are saved, and the yield of the sample can be greatly improved.

Description

Technical field [0001] The invention belongs to the technical field of plant extraction and separation, and specifically relates to an effective part of apple flowers, a preparation method and a method for extracting kaempferol glucoside by using the effective part of apple blossoms. Background technique [0002] The apple flower is the dried flower of the Rosaceae Malus Pumila Mill. The main components of apple blossoms are dihydrochalcones such as phloretin and phlorizin; other flavonoids such as quercetin, kaempferin, rutin and so on. It has the effects of curing diabetes, metabolic syndrome and neurological diseases, anti-oxidation, improving memory, beauty and whitening. The processed apple blossom tea has the effects of nourishing blood, improving eyesight, detoxifying, treating neuralgia and removing acne. [0003] Kaempferol derivatives have analgesic, promote skin pigmentation, anti-allergic and other activities. At present, kaempferol-3-O-glucoside is extracted from saf...
