Problems solved by technology

Although ancient books record a large number of classic examples of Phoebe being used in medicine, the chemical composition and health-preserving medicinal principles of Phoebe have not been confirmed by modern medicine
[0006] Although there are also some patents about wood essential oil and technology at present, such as steam distillation combined with supercritical CO2 extraction method for preparing cypress essential oil (application number: CN201210339865.1), cypress essential oil and cigarettes containing cypress essential oil (application number: CN201010044402.3 ), a production process and equipment for extracting rosewood essential oil from rosewood sawdust (application number: CN201510187394.0), a natural health-care essential oil of moringa (application number: CN201510256307.2), but about Phoebe essential oil and its preparation method Research papers and patent reports are basically blank
Phoebe is a precious resource, and its processing waste has not been effectively utilized. Although the above-mentioned method of extracting essential oils is mentioned, the process is complicated, the efficiency is average, and the safety needs to be improved. Moreover, the wood structure and composition of different tree species are different. Therefore, the above-mentioned method does not Suitable for the extraction of nanmu essential oil

Abstract

The invention discloses Phoebe zhennan essential oil and a preparation method thereof, comprising the following steps: first, pretreating Phoebe zhennan wood to obtain pretreated Phoebe zhennan wood; second, adding the pretreated Phoebe zhennan wood into an extraction device; third, isolating essential oil containing a solvent from the extraction device; fourth, isolating the essential oil and the solvent; fifth, dewatering the essential oil; in the first step, the wood is from Phoebe, Machilus and their closely related tree species, and the pretreatment includes: naturally air-drying or drying and then crushing materials of Phoebe zhennan, such as bark, trunk, roots, shoots, branches, flowers and fruits, and screening under 2-100 meshes after crushing. The invention has the advantages that the Phoebe zhennan essential oil has the special effects such as antisepsis and anti-inflammation, corrosion resisting and insect controlling, treatment of elderly chronic bronchitis, local anesthesia, treatment of colitis, antibechic and expectorant effects, treatment of stomach diseases and conjunctivitis, analgesia, and wind dispelling and damp eliminating; the preparation method is high in extraction efficiency, green and safe, and simple to operate.

Description

technical field [0001] The invention relates to the field of daily chemical industry, in particular to nanmu essential oil and a preparation method thereof. Background technique [0002] Phoebe in a broad sense includes Phoebe (formerly known as Zhennan, Phoebe Nees) and Runnan (Machilus Nees) and their related genera. Phoebe wood has fine structure, stable wood, beautiful texture and easy processing. It is an important building and furniture material in ancient my country. It was exclusively used by the royal family during the Ming and Qing Dynasties. Phoebe has a profound cultural background. From palaces to mausoleums, from seats to beds, as a carrier of Chinese culture, it reflects the royal culture of Chinese feudal society and the aesthetics of literati and officials, and embodies the essence of wood culture in architecture, furniture and artwork. . (The fragrance of nanmu is elegant and long,) Living in the elegant room decorated with nanmu for a long time, accompan...
