Embodiment 1

[0013] Harvest the flowering branches and leaves of the copper-tolerant / accumulating plant A. haizhouensis planted in copper-polluted soil in Fuyang, Zhejiang Province during the full-flowering stage. After washing, air-drying, and crushing, pass through a 40-mesh sieve, weigh 1000g and put it into 5L of supercritical CO 2 In the extraction kettle, pass CO 2 , extraction temperature 45°C, extraction pressure 15MPa, CO 2 The flow rate is 40.3~51.0L / h, extract for 2.0 hours; then use the separator I and II to dissolve the CO 2 The extract in the fluid is separated, the pressure of the separation tank I is 8MPa, and the temperature is 60°C; the pressure of the separation tank II is 4.6MPa, and the temperature is 35°C, and the fragrance is obtained as a yellow oil with a strong smell and a good fragrance. The yield is 4.08%. . The atomic absorption spectrometry determines that the copper content in the fragrance is less than 0.1ppm.

Embodiment 2

[0016] Harvest the flower branches and leaves of the copper-tolerant / enrichment plant Azalea haizhou planted in the polluted soil of Zhuji Copper Mine in Zhejiang Province at the full flowering stage, wash, air-dry, crush, pass through a 40-mesh sieve, weigh 1000g and put it into 5L of supercritical CO 2 In the extraction kettle, adopt the process parameter supercritical extraction among the example 1. The yield of extracting flavor is 3.68%. The atomic absorption spectrometry determines that the copper content in the fragrance is less than 0.1ppm.

[0017] GC / MS identified its components, the total ion current as figure 2 As shown, it can be seen from the figure that the natural fragrance contains dehydroaranone, aneranone, caryophyllene and its oxides. The relative contents of dehydrocaryophyllene and caryophyllene were 73.1% and 3.86%, respectively, and the contents of caryophyllene, α-caryophyllene, and caryophyllene oxide were 7.57%, 0.72%, and 1.69% by GC / MS library s...

Abstract

The method of extracting perfume from Haizhou elscholtzia planted in copper polluted soil includes the following steps: 1. collecting flower branch and / or leaf in the flowering stage, crushing to 40 mesh, and supercritical extracting inside an extracting caldron in flow rate of 40.3-51.0 L / hr, pressure of 15-18 MPa and temperature of 35-45deg.c for 1.0-2.0 hr; and 2. separating the extract in CO2 in the first separating caldron at pressure of 8-10 MPa and temperature of 60 deg.c and the second separating caldron at pressure of 4-6 MPa and temperature of 35 deg.c to obtain the perfume. The present invention has simple technological process, high yield, and high quality of the obtained perfume product.

Description

technical field [0001] The present invention relates to the method for extracting spices from the Herba Cinnamomi which is planted in copper-contaminated soil, especially with supercritical CO 2 A method for extracting natural spices from Herba chinensis. Background technique [0002] The copper-tolerant / accumulating plant A. haizhouensis grown in polluted soil has a specific odor, and its volatile substances include dehydrocarnationone and caryophyllone, which are antibacterial components, and caryophyllene and caryophyllene oxide, which are fragrance components. With the large-scale planting of phytoremediation of copper-contaminated soil in Haizhou, the post-harvest disposal of phytoremediation materials is an environmental problem that needs to be solved urgently. After a large amount of copper-rich Azalea haizhou plants are harvested, if they cannot be disposed of as soon as possible and reasonably, the heavy metals absorbed by the plants may return to the soil, and th...
