Abstract

The invention discloses acylation flavone glycoside named camellikaempferoside A and a preparing method and application thereof. At first, the structure of camellikaempferoside A is provided, and then a method for separating camellikaempferoside A from Fuzhuan tea to prepare and obtain camellikaempferoside A is provided; when a monomeric compound is prepared, at first, Fuzhuan tea is taken and smashed; then organic solvent is used for extracting the smashed Fuzhuan tea, and an extracting solution is concentrated in a pressure reducing mode to prepare paste extract; the paste extract is separated and purified to obtain camellikaempferoside A. The invention further provides application of acylation flavone glycoside named camellikaempferoside A to preparation of medicine for resisting breast cancer (MCF-7 and MDA-MB-231). The acylation flavone glycoside with bioactivity has great significance in the agriculture and medicine field, and provides a wide prospect for effectively developing and utilizing the Fuzhuan tea; the preparing method is simple and low in cost.

Description

technical field [0001] The invention belongs to the field of chemical technology, and in particular relates to an acylated flavone glycoside named tea kaempferol A, a preparation method and application thereof. Background technique [0002] Camellia sinensis and its leaf processed products such as green tea, black tea, black tea, etc. contain flavonoids and flavonoid glycosides with good biological activity, which are very important natural organic compounds in nature. As early as 1991, Finger et al. identified 20 flavonoids and their glycosides from fresh tea leaves, black tea, and green tea. Zou Yanli et al. also isolated three flavonoids from Pu'er cooked tea. Therefore, it shows that tea products contain a lot of flavonoid active biological ingredients that have the functions of preventing cardiovascular disease, antibacterial, and anticancer. These natural ingredients with health care effects have attracted people's attention, and this will also become a research hotspo...
