Abstract

A preparation method of Acronychia pedunculata essential oil comprises: subjecting wood powder of Acronychia pedunculata to supercritical CO2 extraction to obtain Acronychia pedunculata extract; subjecting the Acronychia pedunculata extract to microfiltration purification to obtain the Acronychia pedunculata essential oil. The Acronychia pedunculata essential oil is extracted herein via the supercritical CO2 extraction technique; no organic solvents are added during extraction; the Acronychia pedunculata essential oil prepared herein is purer; matters of different molecular weights are separated via the filter membranes having different diameters, and the essential oil is thereby purified; the preparation method has mild conditions, high extraction efficiency and zero damage to thermosensitive matters.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a method for preparing essential oils of essential oils. Background technique [0002] Jiangzhenxiang, also known as: wisteria fragrance, chicken bone fragrance. Leguminous sandalwood belongs to rattan, which is a kind of perennial woody vines. Dalbergia japonica and Dalbergia oblique leaf are injured and secrete oil to repair wounds. The vine is called Jigouteng in Song Dynasty, also known as Wuliteng and Meilongteng. In Hainan Li language, it is called Teng Zongguan, and the Miao people call it Teng Guan Teng. [0003] Jiangzhenxiang generally takes more than 50 years to produce fragrance. The oil of Jiangzhenxiang is mainly concentrated in the injured place. Generally, the oil is easy to accumulate on the fork of the rattan, the infected part of the injury, and the wound site, and the oil is rich and fragrant. The main chemical components are: besquiterpene, flavonoids (derivati...
