Problems solved by technology

[0004] Since the material composition of plant extracts will vary greatly depending on the preparation process, the above-mentioned techniques for obtaining grape seed extracts have their own advantages and disadvantages, but they all have their unique values. Therefore, the methods for grape seed extracts continue to be improved. It still has practical significance. In addition, there are few compound compositions made from grape seed extract and other plant extracts, mainly including: grape seed extract, soybean oil extract, and vitamin E in CN200910018841.4; CN200910041097. X Grape seed extract 120g, pearl powder 50g, vitamin E 10g, beeswax 10g, soybean oil 310, etc. It is people's goal to find plant materials that are used in conjunction with grape seeds to take advantage of the combination

Embodiment 1

[0036] Embodiment 1 grape seed extract

[0037] Take 500g of grape seeds and place in SFE-CO 2 In the extractor, the extraction temperature is 40°C, the analytical pressure is 6-8Mpa, the analytical temperature is 40°C, the extraction pressure is 30Mpa, and the extraction time is 3 hours to obtain volatile oil and fat-soluble components;

[0038] SFE-CO 2 After extracting the volatile oil and fat-soluble components, add 9 times the amount of 70% ethanol to immerse at room temperature for 12 hours, filter, and collect the medicinal liquid; then add 9 times the amount of 70% ethanol to immerse at room temperature for 12 hours, filter, Discard the medicinal residues, combine the medicinal liquids, concentrate under reduced pressure at 0.07 MPa, recover ethanol, and spray-dry to obtain a solid powder.

[0039] 48.7g of total grape seed extract was obtained, including 0.7g of volatile oil, 5g of fat-soluble components, and 43g of solid dry powder.

Embodiment 2

[0040] Embodiment 2 grape seed extract

[0041] Put 500g of grape seeds, 500g of black beans, and 500g of Baiying into SFE-CO 2 In the extractor, the extraction temperature is 50°C, the analytical pressure is 6-8Mpa, the analytical temperature is 35-40°C, the extraction pressure is 24Mpa, and the extraction time is 2 hours to obtain volatile oil and fat-soluble components;

[0042] SFE-CO 2 After extracting the volatile oil and fat-soluble components, add eight times the amount of 80% ethanol to soak at room temperature for 24 hours, filter, and collect the medicinal liquid; then add eight times the amount of 80% ethanol to soak at room temperature for 24 hours, filter, Discard the medicinal residues, combine the medicinal liquids, concentrate under reduced pressure at 0.07 MPa, recover ethanol, and spray-dry to obtain a solid powder.

[0043] 158.3 g of total grape seed extracts were obtained, including 3.3 g of volatile oil, 17 g of fat-soluble components, and 138 g of sol...

Embodiment 3

[0044] Example 3 Grape Seed Extract Soft Capsules

[0045] Grape seed extract (prepared by the method of Example 1) 2.5kg vitamin E97.3g

[0046] PEG4005kg Glycerin 1kg Tween 801kg.

[0047]Mix the volatile oil, fat-soluble extract, and Tween 80 evenly, add PEG400 equivalent to 1 / 2 of the volatile oil, and mix evenly to obtain a volatile oil emulsion; take glycerin, the remaining PEG400, solid dry powder and the remaining water, mix Homogenize for 30 minutes with a homogenizer, then add volatile oil emulsion and mix evenly, and homogenize for 30 minutes with a homogenizer to get ready.

[0048] The content of the soft capsule contains 16g of proanthocyanidins and 0.973g of vitamin E per 100g.

Abstract

The invention relates to novel grape seed extract and a preparation method thereof. Each part of the grape seed extract is made from 5-10 parts of grape seed by weight. The grape seed extract comprises volatile oil, liposoluble constituent and solid dry powder. The preparation method includes the steps of SEF-CO2 (supercritical CO2) extraction and ethanol extraction. The grape seed, black bean and bittersweet herb can also be used as raw materials to prepare the grape seed extract, and the grape seed extract with vitamin E, PEG400 (polyethylene glycol 400), glycerin and tween 80 is made into soft capsules. The grape seed extract fully retains effective constituents in plant materials, and is suitable for general population. 300 cases of use by different people show that average functional effective rate reaches more than 94.5%.

Description

technical field [0001] The invention belongs to the field of health care products, in particular to a novel grape seed extract and a preparation method thereof. Background technique [0002] Grape seed extract is rich in proanthocyanidins OPC, which is the most efficient antioxidant and free radical scavenger found in plant sources so far. Grape seed is recognized as the best beauty and anti-aging nutritional supplement in Europe, and has the reputation of "skin vitamin" and "oral cosmetics". It has unique effects of moisturizing skin, whitening and removing chloasma. [0003] There are many ways to prepare grape seed extract, such as: the traditional process of water extraction and alcohol precipitation represented by CN00134314.9; the process of organic solvent extraction represented by CN200710191255.0, and then refined with macroporous resin; Superfine pulverization technology represented by CN200610104864.3; organic solvent extraction of inorganic mineral acid represe...
