Abstract
The invention provides plant extract with blood lipid reducing and blood pressure lowering effects, and a preparation method and an application thereof. The preparation method comprises the steps of mixing the flower and/or the flower bud of Chrysanthemum morifolium, extracting with 50-80% (v/v) aqueous ethanol at 60-100 DEG C for 1-3 hours to obtain extractive solution, adsorbing with macroporous adsorption resin, eluting with 60-90% (v/v) aqueous ethanol, collecting eluate, and drying until water content is lower than 12% to obtain the plant extract. The inventive extract contains more than 50% of effective ingredients such as galuteolin, celereoside, luteolin, apigenin, acacetin-7-rhamnosidgluoside, acacipetalin, flavonoid glycoside, and chlorogenic acid; and has blood lipid reducing and blood pressure lowering effects. Compared with the existing domestic and overseas products, the inventive extract has more complete efficacy, and more ideal effects in restoring normal blood lipid level and blood pressure level for demanded people.
Description
(1) technical field
The present invention relates to hypotensive plant extracts of a kind of reducing blood lipid and preparation method thereof, with and application in preparation reducing blood lipid hypotensive double effects functional food.
