Uses and functions of Pine Needle Extract.

Functions and Indications Pine needles: dispelling wind and drying dampness, killing insects and relieving itching. Pine knots: dispelling wind and drying dampness, relaxing tendons and collaterals; dispelling wind and benefiting qi, collecting dampness, stopping bleeding; promoting blood circulation and relieving pain.

Used in the treatment of: influenza, rheumatism, arthralgia, swelling and pain, night blindness, hypertension, neurasthenia.

1. In the application of medicine pine needles have hypolipidemic, hypoglycaemic, analgesic and anti-inflammatory, cough, expectorant and asthma and other pharmacological effects, so it can be used in medicine. Chinese medicine has pine needles with Chinese medicine, decoction, treatment of malnutrition oedema, neurasthenia and other effects.

Folk use to drink wine made of pine needles to regulate blood pressure. Huang Shundong's research report shows that pine needles are commonly used as one of the components of herbal medicine.

2. Application in animal husbandry pine needles are rich in nutrients and can be used for feed processing. At present, in our country is mainly through the pine needles processed into pine needle powder, added to the feed used.

Pine needle powder added to livestock and poultry feed can improve livestock and poultry production performance, improve livestock and poultry meat quality, at the same time can enhance the immune function and disease resistance of livestock and poultry.

3. Application in the food industry due to the pine needles contain flavonoids, lignans, mangiferin, vitamins and other active substances, and thus can produce health food. At present, pine needle drinks in Japan, Russia, Europe and other regions are very popular.

In China, there are pine needles processed into cloudy drinks, clarified drinks, pine needle milk drinks or pine needles and other raw materials according to a certain proportion of mixed fermentation into health care products and pine needles directly into the development of pine needle tea research.

Pharmacological Effect of Pine Needle Extract.

1.Anti-platelet aggregation activityPine needle extract lignans and proanthocyanidins have significant anti-platelet aggregation activity in vivo.

Their activity in preventing platelet aggregation may be mediated by stimulating the production of nitric oxide by endothelial cells and inhibiting the production of thromboxane A2.

In addition, affecting the passage of calcium ions across the plasma cell membrane is one of the possible mechanisms.

However, the material basis for the in vitro antiplatelet aggregation activity of pine needle extract is polyphenolic compounds such as flavonoids and not lignans and proanthocyanidins, which are present in large quantities in the plant, as previously expected.

2. Hypoglycaemic effect By giving mice continuous gavage of pine needle extract, its effect on blood glucose in normal mice as well as on blood glucose in hyperglycaemic mice induced by adrenaline and tetroxine was observed.

The results showed that pine needle extract 200, 400 and 800 mg/kg had no significant effect on the blood glucose level of normal mice, but all of them could reduce the blood glucose of hyperglycemic mice induced by adrenaline and tetroxosine, and showed a good dose-dependence.

It is suggested that pine needle extract has significant hypoglycaemic effect.

3. Antibacterial effect of pine needle extract antibacterial effect is good, its antibacterial components are piperone, thujaplicin, methyl piperitol, Douglas fir, hibiscus acid and so on.

4. Anti-aging effect of pine needles significantly increase the activity of antioxidant enzymes and total antioxidant capacity of aged rats, reduce the content of free radical metabolites to improve the activity of tissue membrane enzymes, change the membrane lipid fluidity, indicating that pine needles can improve the body's ability to resist free radicals, reduce lipid peroxidation, thereby protecting the integrity of the cell membrane and the normal function of the cell membrane play a role in slowing down the role of aging.

Pine needle extract can significantly promote the weight increase of mouse thymus and spleen, improve the phagocytosis function of mouse reticuloendothelial system, and have the effect of hypoxia resistance and anti-fatigue.

This indicates that pine needles can also play a role in delaying aging by improving the immune function of the body.

Extraction method of Bulk Pine Needle Extract Powder.

1. Organic solvent extraction method with 20% ethanol solution for extraction: fresh pine needles washed to remove the old leaves, air-dried and weighed, cut about 2cm, 20% ethanol solution soaked overnight, 60 ℃ water bath reflux 8h filtration, the slag plus 20% ethanol solution soaked overnight, 60 ℃ water bath reflux 8h filtration.

Slag plus 20% ethanol solution soaked overnight, 60 ℃ water bath reflux 8h filtration, combined with three times the filtrate, distilled and concentrated to extract with rotary evaporator.

2. Supercritical extraction method was used to extract the terpenoids in the needles of Pinus sylvestris with supercritical CO2 supercritical extraction technology. The results showed that the extraction pressure of 15 MPa, extraction temperature of 40 ℃ and extraction time of 20 min were the extraction conditions with higher yield of terpenoids represented by α-pinene and β-stigmasterol from the needles of Pinus sylvestris.

Compared with water vapour distillation, the supercritical fluid extraction method can preserve a large number of thermally unstable components and easily oxidized components due to the lower operating temperature, which maintains the natural quality of the chemical components and the high yield of the samples.
