Embodiment

[0021] 1. Preparation of the extract

[0022] (1) First take out the fresh iron nail dishes, wash and drain them, then pulverize them into iron nail dishes powder by a tissue grinder;

[0023] (2) Then take the pulverized iron nail dish powder, mix it according to the ratio of iron nail dish powder: distilled water = 1g: 30mL, and extract twice in a water bath at 90-100°C for 1 to 2 hours each time, and filter the filtrate with suction;

[0024] (3) Then at 65°C and -0.09MPa, the obtained filtrate was concentrated under reduced pressure to 33% of the original volume of the filtrate, and absolute ethanol was added to make the volume fraction of the absolute ethanol in the mixed system 75%. After 24h of sedimentation, centrifuge at 4000r / min for 5min to obtain the supernatant and alcohol sediment;

[0025] (4) At 65°C and -0.09MPa, take the supernatant and concentrate it under reduced pressure, and then freeze-dry it under vacuum at -80°C to obtain the water extraction and alcohol preci...

Abstract

The invention discloses application of an ishige okamurae extract in preparation of seaweed-derived skin care products. Researches show that the ishige okamurae extract has higher antioxidant activityand anti-tyrosinase activity, thus being expected to become a good base material for development of the seaweed-derived antioxidant skin-whitening skin care products.

Description

Technical field [0001] The present invention relates to the technical field of cosmetics, and specifically relates to the application of an extract of Nasalpinia japonica in the preparation of seaweed source skin care products. Background technique [0002] In recent years, various skin care products with whitening, moisturizing, anti-aging, and freckle removal effects have emerged one after another. One of the techniques for preparing the above-mentioned skin care products is to use plant extracts as additives. Studies have pointed out that seaweeds are caused by the special nature of the habitat. It has a chemical composition that is quite different from that of land and shore plants, and contains various antioxidant active ingredients such as polysaccharides and polyphenols. It is a potential resource for the development of natural antioxidant skin care products. [0003] The brown algae Ishige okamurae (Ishige okamurae), which is distributed in the rocks in the middle and high ...
