Problems solved by technology

[0007] It is reported in the literature that the traditional extraction process of volatile components of Pandanus mainly adopts the steam distillation method, but this extraction method has the disadvantages of low extraction efficiency, easy decomposition of heat-sensitive substances, and poor selectivity, while supercritical CO 2 Extraction, a new green chemical technology, can overcome the above shortcomings to a certain extent. Not only does the product contain no residual solvents, the extraction process has no pollution to the environment, but it can also keep the active ingredients from being destroyed and has a high extraction rate. It is especially suitable for use in Extraction of active ingredients of fat-soluble and low-grade traditional Chinese medicine

Abstract

The invention discloses a method for extracting volatile components from Pandanus amaryllifolius Roxb leaves by use of a supercritical CO2 extraction method. The method can obtain 151 compounds from the volatile components of Pandanus amaryllifolius Roxb, but a steam distillation method only can obtain 95 compounds, and extra 56 compounds, such as n-heptatriacontanyl alcohol, methyl linolenate, phytyl acetate, 3-hydroxyl-7 (isonitroso) ursodeoxycholic acid and dihydroactinidiolide, which cannot be obtained by the steam distillation method, are obtained by the method provided by the invention. The method for extracting the volatile components from Pandanus amaryllifolius Roxb leaves is superior to the steam distillation method in the aspects of smell, yield, chemical composition, squalene yield and extracting efficiency.

Description

technical field [0001] The invention relates to the technical field of extraction and separation, in particular to a method for extracting the volatile components of the pandanus from the leaves of the pandanus. Background technique [0002] Pandanus leaves are the fresh leaves of Pandanus amaryllifolius Roxb (Pandanus amaryllifolius Roxb). Xiangludou is an evergreen herb, the leaves are about 30cm long and 1.5cm wide, with occasional thorns on the leaf margins, slightly dense thorns on the leaf tips, slightly thorns on the apex of the back of the leaves, a narrow white film on the leaf sheath, and no flowers and fruits. The origin is Maggulu Islands, Indonesia. Studies have found that Pandanus is suitable for the acidic red soil in southern my country, but due to temperature restrictions, it is only suitable for growing in the southern subtropical zone to the tropical region of my country. [0003] At present, there are few studies on the chemical components of Pandanus a...
