Technical Field

The invention relates to the technical field of pine needle extraction, in particular to a method for extracting natural negative oxygen ions from pine needles.

Background

Pine needles, also known as pine leaves, pine leaves with bristles, pine hairs or pine whiskers, are leaves of plants belonging to the genus Pinus of the family Pinaceae, are needle-like in shape, and are one of the main byproducts of plants belonging to the genus Pinus. Pinus massoniana, Pinus armandi, cedar, Korean pine, Pinus thunbergii, Chinese pine, slash pine, Yunnan pine and the like are medicinal pinus plants. Pine needles are the main medicinal part of plants in the genus pinus. Pine needle oil, also known as fir oil. Is prepared from needle and twig of fir of Pinaceae by steam distillation. As a colorless to pale yellow liquid. Has the characteristic balsam fragrance and spicy smell of the fir leaves. The perfume is mainly used for daily use essences such as perfumed soaps, perfumes, air fresheners, deodorants and the like, and is also used for foods such as candies, baked foods, beverages and the like. The existing pine needle extraction method has more working procedures and poor quality of the produced crude oil.
