Method for extracting volatile oil from agilawood seeds, and usage and application of volatile oil

Abstract

The invention discloses a method for extracting a volatile oil from agilawood seeds, and a usage and an application of the volatile oil. In the method disclosed by the invention, a supercritical CO2 fluid extraction method is adopted to extract volatile components from aquilaria sinensis seeds; and a DPPH method is used to study anti-oxidation capability of effective components of the volatile components. With the method, squalene with relatively high content is detected in the aquilaria sinensis seeds for the first time; and the volatile oil has a certain anti-oxidation capability, so that scientific basis is provided for further studying active components of the aquilaria sinensis seeds development and utilization The extraction method is simple in process flow, high in extraction yield and low in extraction temperature, and can prevent degradation of heat-sensitive components. The method fully develops rich resources of the agilawood rare medicinal material, and makes the best use of the agilawood. With the method, effective components in the agilawood seeds are extracted simply and effectively, thereby developing novel raw materials and extraction process for the squalene.

Description

【Technical field】 [0001] The invention relates to a method for extracting the extract of agarwood seeds, in particular to a method for extracting volatile oil from the seeds of agarwood. The invention also relates to the use and application of the volatile oil of the agarwood seed extract, belonging to the technical fields of biomedicine and health care. 【Background technique】 [0002] Aquilaria sinensis (lour.) Gilgl. Resin-containing wood is called agarwood, also known as domestic agarwood, earth agarwood or Guanxiang. Aquilaria sinensis is also the only plant resource for producing agarwood medicinal materials in my country. The wild resources of Acacia sinensis are on the verge of extinction, and it has been listed as a national rare and endangered third-level protected plant and a national second-level key protected plant. Agarwood, pungent, bitter, warm in nature, has the effects of promoting qi and relieving pain, warming the middle and relieving vomiting, inducing qi...

Problems solved by technology

Due to the high content of squalene in the liver of deep-sea sharks, such as 40%-74% in armored shark liver oil, and 49%-89% in small spiny sharks, most of them currently use deep-sea shark liver oil to extract squalene; but The production of squalene in such a large amount will lead to the ecological imbalance of deep-sea sharks

[0005] In recent years, a small amount of methods for extracting squalene from plants have also been announced. Chinese patent (CN201110027119.4) "Method for extracting squalene from camellia oleifera seeds and tea oil squalene soft capsules" is based on extraction, chromatographic separation Combined with normal temperature extraction and supercritical extraction several extraction methods to extract suitable high-purity squalene; The separation process combined with silica gel chromatography extracts high-purity squalene; the Chinese patent (CN201010190275.8) "Method for Extracting Squalene from Vegetable Oil Deodorization Distillate" uses molecular distillation, extraction, and crystallization to extract high-purity squalene. Concentration of squalene; these methods require a combination of multiple extraction methods, the process is more complicated, and other chemical substances are introduced, and it is difficult to control the process
