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 in particular relates to an effective part of apple flowers, a preparation method and a method for extracting kaempferol glucoside using the same. Background technique [0002] Apple blossoms are the dried flowers of Malus Pumila Mill, an apple plant in the Rosaceae family. The main components of apple blossoms are dihydrochalcones such as phloretin and phlorizin; other flavonoids such as quercetin, kaempferol, rutin and so on. It has the effects of treating diabetes, metabolic syndrome and neurological diseases, anti-oxidation, improving memory, and beauty and whitening. The processed apple scented tea has the effects of nourishing blood and improving eyesight, detoxifying, treating neuralgia, and removing acne. [0003] Kaempferol derivatives have activities such as analgesia, promotion of skin pigmentation, and anti-allergy. At present, kaempferol-3-O-glucoside is...
