Problems solved by technology

[0003] At present, the extraction methods of pine pollen are mostly pure water extraction, ethanol extraction, enzymatic extraction, etc., and the final product needs to be concentrated, dried or blended to obtain the final product. The process is complicated, the cost is high, and the yield is often not high, so it is not suitable for Industrial production; and the process may need to introduce other organic agents that are irritating to the skin, which will greatly increase the risk of sensitization and is not suitable for adding to cosmetics

Embodiment 1

[0025] A preparation process of pine pollen extract, the steps are as follows:

[0026] (1) the pine pollen is subjected to wall-breaking treatment to obtain the broken-wall pine pollen;

[0027] (2) Using 1,3-propanediol as the extractant, take 5g of the broken-walled pine pollen from step (1) for extraction, the weight ratio of the extractant to the broken-walled pine pollen is 10:1, and extract twice under reflux in a water bath at 95°C , each time for 3 hours to obtain the extract;

[0028] (3) The 2 extracts of step (2) were filtered through slow qualitative filter paper respectively, and the obtained filtrate was passed through a 5 μm organic microporous membrane to obtain 97.9 g of pine pollen extract, and the detected flavonoid content was 0.23 mg / mL.

Embodiment 2

[0030] A preparation process of pine pollen extract, the steps are as follows:

[0031] (1) the pine pollen is subjected to wall-breaking treatment to obtain the broken-wall pine pollen;

[0032] (2) adopt the 1,3-butanediol aqueous solution of concentration 60wt% as extractant, get the broken-walled pine pollen of 5g step (1) and extract, extract for the first time according to the weight ratio of extractant and broken-walled pine pollen: 10:1, the second extraction according to the weight ratio of the extractant to the broken wall pine pollen is 8:1, ultrasonic assisted water bath heat reflux extraction, each time 2h, ultrasonic power 120W, to obtain the extract;

[0033] (3) The 2 extracts of step (2) are filtered through slow qualitative filter paper respectively, and the gained filtrate passes through a 0.45 μm organic microporous membrane, and the gained filtrate is added with 0.2wt% MTI to obtain 87.3g pine pollen extract, and detect flavonoids The content is 0.43mg / mL...

Embodiment 3

[0035] A preparation process of pine pollen extract, the steps are as follows:

[0036] (1) the pine pollen is subjected to wall-breaking treatment to obtain the broken-wall pine pollen;

[0037] (2) Adopt the glycerol aqueous solution of concentration 60wt% as extraction agent, get the broken-walled pine pollen of 5g step (1) and extract, extract according to the weight ratio of extractant and broken-walled pine pollen is 10:1, ultrasonic assisted water bath Heat reflux extraction 2 times, 2 hours each time, ultrasonic power 120W, to obtain the extract;

[0038] (3) The 2 extracts of step (2) are filtered through slow qualitative filter paper respectively, and the gained filtrate passes through a 5 μm organic microporous membrane, and the gained filtrate is added with 0.2wt% MTI to obtain 96.4g pine pollen extract, and detect the flavonoid content 0.26mg / mL.

Abstract

The invention belongs to the field of biotechnology, in particular to a preparation process of pine pollen extract. The invention provides a pine pollen extraction process using caprylic capric triglyceride (GTCC), polyol or polyol aqueous solution as an extractant, eliminating the need for processes such as concentration, drying or blending, and the extract is a finished product. The extraction process of the invention is simple and easy, the cost is low, the loss of the pine pollen raw material is small, the maximum utilization of the raw material is achieved, and the method is suitable for industrial production. The present invention adopts caprylic capric triglyceride (GTCC) or polyhydric alcohol which is the least irritating to skin, which has little irritation to human skin, low sensitization, and good compatibility with cosmetic matrix; and the pine pollen extract is rich in Flavonoids and oil components have whitening, anti-aging, anti-inflammatory and antibacterial effects, and are very suitable as active ingredients for cosmetics.

Description

technical field [0001] The invention belongs to the field of biotechnology, in particular to a preparation process of pine pollen extract. Background technique [0002] Pine pollen is a kind of pollen that can be used for both medicine and food. It is a traditional medicinal material with a history of thousands of years. It is rich in more than 200 nutrients and is a complete nutrient. Active ingredients such as pollen flavonoids have whitening, anti-aging, antibacterial and anti-inflammatory effects, and are often used in cosmetics. [0003] At present, the extraction methods of pine pollen are mostly pure water extraction, ethanol extraction, enzymatic extraction, etc., and the final product needs to be concentrated, dried or blended to obtain the final product. The process is complicated, the cost is high, and the yield is often not high, so it is not suitable for Industrial production; and the process may need to introduce other skin-irritating organic agents, which wil...
