Embodiment 1

[0035] Experimental materials, instruments and reagents:

[0036] Material: Dried macadamia nut green skin, macadamia nut green skin fruit.

[0037] Instruments: ultrasonic extractor, 7200 spectrophotometer, centrifuge, water bath

[0038] Reagent samples: absolute ethanol, phosphate buffer, 1% NAOH, tyrosinase, tyrosine, DPPH, anthrone, concentrated sulfuric acid, glucose.

[0039] Experimental steps:

[0040] Extraction of polyphenols from macadamia nut green bark:

[0041] Take 10g of macadamia nut green husk powder, add 50ml of warm water to extract three times, a total of 150ml of water, then add 7.5ml of 5% sulfuric acid to the flask, cold soak for 24h, filter; then wash the filter cake with deionized water to remove residual sulfuric acid, until washing The liquid is neutral, and the polyphenols of the crudely extracted macadamia nut green bark are obtained.

Embodiment 2

[0080] Extraction of polysaccharides from macadamia nut green bark:

[0081] Take by weighing 10g of dry macadamia nut green husk powder, which is tan and viscous, so as to obtain light tan macadamia nut green husk powder. Fresh macadamia nut green skin, after dehydration, obtains a pink viscous substance, and after drying at a low temperature of 40°C, its powder is a dark purple powder. Fresh macadamia nut green peels and dried macadamia nut green peels are extracted with polysaccharides, and the resulting polysaccharides, fresh macadamia nut green peels contain more gum than dried macadamia nut green peels, 10g macadamia nut green peels are extracted, dried macadamia nut green peels get 6.894g of polysaccharides, fresh macadamia nut green peels get 6.894g of polysaccharides, fresh macadamia nut green peels get Polysaccharide 4.743g. Fresh macadamia nut green skin has a higher water content, so the same weight of fresh macadamia nut green skin and dried macadamia nut green s...

Abstract

The invention provides a macadamia nut green peel extract, namely macadamia nut green peel polyphenol or macadamia nut green peel aqueous extract which is prepared with the following method: taking macadamia nut green peel powder, adding warm water for water extraction three times, then adding 5% sulfuric acid, keeping quenching for 24h, and filtrating; washing a filter cake with deionized water to remove residual sulfuric acid until the washing liquid is neutral, and obtaining the macadamia nut green peel polyphenol; or washing macadamia nut green peel original crude drug coarse powder with water, putting into boiling water, boiling for 30min, stopping heating, keeping the water temperature at 60 DEGC-70 DEG C, performing ultrasonic extraction for 1h, centrifuging an aqueous extraction liquid at 2000r/min for 4min to obtain a supernatant liquid, then concentrating the supernatant liquid to thick paste, and obtaining the macadamia nut green peel aqueous extract. The macadamia nut green peel extract is used for preparing toning lotion and toning cream. The invention also provides application of the macadamia nut green peel polyphenol or macadamia nut green peel aqueous extract to preparation of cosmetics, as well as application to preparation of a tyrosinase inhibitor and preparation of an antioxidant.

Description

technical field [0001] The invention belongs to the field of plant natural extracts and cosmetics, and in particular relates to a macadamia nut green husk extract, a cosmetic using it as an active ingredient and a preparation method thereof. Background technique [0002] Macadamia ternifolia F.Muell belongs to the Proteaceae family (Proteaceae), Macadamia (Macadamia), is an evergreen tree, dicotyledons, native to the subtropical rainforests of Queensland and New South Wales, Australia. Macadamia nut kernels have a unique flavor and rich nutritional content. They are one of the four famous nuts in the world. In Europe and America, they are considered to be one of the best table nuts in the world. [0003] Macadamia nuts were introduced to China in the 1960s and 1970s. In recent years, my country's Yunnan Province has vigorously developed and has initially formed an industry. Especially after the introduction and cultivation in Dehong Prefecture, it has been planted on a larg...
