Method for black pine needle volatile oil extraction and component analysis through water vapor method

Abstract

The invention discloses a method for black pine needle volatile oil extraction and component analysis through a water vapor method. According to the method, the heating on two groups of devices are simultaneously stopped, water is continuously introduced, and cooling is performed for about 30 min; and after the cooling, the condensing pipe inner pipe in one group of the device is rinsed with a n-hexane solution, the rinsing liquid is poured into a flat-bottomed flask, and the condensing pipe inner pipe in the other group of the device is rinsed with a diethyl ether solution; the solutions in the two flat-bottomed flasks are respectively poured into two separatory funnels, and standing liquid separation is performed to obtain two extraction liquid; and after the ending, two volatile oil extraction liquids are obtained, and the component contents in the two extraction liquids can be analyzed by a user, or the component content can be analyzed after the two extraction liquids are mixed. In the prior art, when the black pine needle volatile oil and component analysis method is used, the black pine needle volatile oil and component analysis method difficultly weakens the influence of different extractants on the volatile oil extraction structure so as to affect the accuracy of the detection result of the black pine needle volatile oil and component analysis method. According to thepresent invention, the problem in the prior art can be avoided with the method of the present invention.

Description

technical field [0001] The invention belongs to the technical field of extracting volatile oil from black pine needles, and in particular relates to a method for extracting volatile oil from black pine needles by a steam method and a component analysis method. Background technique [0002] Pine needles, the leaves of pine trees, are shaped like needles, so they are called. Pine needles are the needles of Siberian Korean pine, black pine, Chinese pine, Korean pine, Huashan pine, Yunnan pine, Simao pine, and masson pine in the genus Pinus. Pine needle extract can be used to expand arteries, increase the oxygen-carrying capacity of red blood cells, promote blood circulation, improve the function of capillaries, improve immunity, increase hormone secretion, strengthen essence, and rejuvenate body tissues. Tests have found that pine needle extract is rich in active substances such as sugar, crude protein, crude fat, various amino acids and various trace mineral elements, various...
