colorless or light yellow liquid. There is a turpentine-like aroma, with a cool pine, pine needles smell.
The fresh needles of Pinus koraiensis in Northeast China were prepared by water distillation, or the biennial needles of Pinus massoniana in South China were prepared by steam distillation.
Korean pine needle oil is mainly used for the preparation of soap and cosmetic flavor. Pine needle oil for the preparation of daily necessities, soap, cosmetics, can also be used as a spray disinfectant.

introduction | pine oil is a kind of essential oil, which is extracted by distillation from pine needles. Pine oil is often used in spice massage and aromatherapy. It can also be used as a fragrance component of bath oil and has a bactericidal effect. |
Main ingredients | The main ingredients of pine needle oil are borneol acetate, pinene, tricyclene, sandalene, limonene, camphene, and dipentene, Enene, fichene, carene, juniene, hydrocelene, myrcene, terpineene, basil, isosinene, p-isopropyltoluene, leaf oil, isornyl acetate of acetic acid and pine oil ester, borneol, red myrcene, it also contains lauraldehyde and decanal in European fir oil. |
efficacy and function | pine needle essential oil, that is, essential oil extracted from pine needles. This oil is rich in unsaturated fatty acids and is an important component for "melting" cholesterol and removing impurities in blood vessels. It can effectively remove excess cholesterol in blood vessels and play a great role in reducing blood viscosity. At the same time, it can also enhance the elasticity of blood vessels and make blood flow smooth. It can regulate blood pressure and has a blood pressure lowering effect on patients with hypertension. Pine needle essential oil is also a secret factor that regulates blood pressure in both directions. Pine needle oil has inhibitory effect on the proliferation of gastric cancer SGC-7901 cells, and the inhibitory effect is obviously enhanced with the increase of pine needle oil concentration. |
application | pine needle oil is obtained by steam distillation of needles and young branches of Pinaceae plants Siberian fir and balsam fir, mainly produced in Yugoslavia, the former Soviet Union, Bulgaria and West Germany. It can be used for perfuming soaps, detergents, disinfectants, deodorants and other cosmetics, as well as in pharmaceuticals and alcohol. |
extraction process | at present, the methods used to extract pine needle oil at home and abroad mainly include steam distillation, organic solvent extraction, ultrasonic method, etc. Among them, the steam distillation hair can be obtained by steam distillation of the needles and young branches of the Pinaceae plants Siberian fir and balsam fir. Supercritical CO2 extraction technology is especially suitable for the separation of unstable natural products and physiologically active substances due to its low extraction temperature, high extraction rate, good separation effect, no solvent residue, short extraction time, energy saving and environmental protection, and high product quality. It has shown strong advantages in the extraction and separation of volatile oil. |
content analysis | accurately weigh about 10g of sample and measure according to ester determination method (OT-18). The equivalent factor (g) in the calculation is 98.15. From this, the total ester content of bornyl acetate is calculated. |
