Problems solved by technology

However, there is still a lot of room for research on the application of the extract of the leaf of the cloth in the field of cosmetics. In particular, there are few studies on the efficacy of the extract of the leaf of the cloth in inhibiting skin pigmentation, whitening, and anti-inflammatory damage.

Abstract

The invention discloses a Dried Microcos paniculata L. leaf extract and a preparation method and application thereof. The dried Microcos paniculata L. leaf extract is prepared by adopting a micro-pressure extraction process, the total flavonoid yield of the obtained dried Microcos paniculata L. leaf extract is improved, no organic solvent residue exists, the method is simple, industrial productionis easy to realize, the problems of low total flavonoid yield, solvent residue and the like of a dried Microcos paniculata L. leaf extraction process in the prior art are solved, and the dried Microcos paniculata L. leaf extract has relatively high application value. Meanwhile, the dried Microcos paniculata L. leaf extract prepared by the invention has the effects of resisting oxidation, resisting inflammatory injury, inhibiting skin yellowish-brown pigmentation, removing yellow, resisting haze and the like, and can be applied to anti-aging and / or anti-inflammatory injury and / or whitening and / or anti-haze skin care products.

Description

technical field [0001] The invention relates to a cloth dregs leaf extract and a preparation method and application thereof. Background technique [0002] Buzaye is the dried leaf of Tiliaceae plant ragleaf (Microcos paniculata L.), with slightly sour taste and cool nature. "Chinese Pharmacopoeia (Part One)" states that it "has the effects of digesting food and eliminating accumulation, clearing heat and promoting dampness, and is used for food stagnation, cold fever, and damp-heat jaundice." Modern studies have shown that Buza leaves are rich in flavonoids, alkaloids, triterpenoids, organic acids and other bioactive components, among which flavonoids are the main active components. Flavonoids have the effects of regulating blood lipids, lowering blood sugar, antithrombotic, removing free radicals in the body, enhancing body immune function, etc. Flavonoids can also improve glucose and lipid metabolism, protect liver and kidney tissues, treat cardiovascular diseases, and ha...
