Problems solved by technology

Among the above methods, the yield of volatile oil in the traditional steam distillation method is relatively low. Taking medicinal materials with an oil content of 2% as an example, this method is generally extracted for about 24 hours, and the yield of volatile oil is 1.0% to 1.3%. The new technology supercritical CO 2 Although the extraction method has a short extraction time and high efficiency, the equipment is complex and expensive, and the extracted volatile oil components are too complex to be suitable for large-scale production

Embodiment 1

[0023] A kind of efficient and swift method for extracting the volatile oil of dalbergia, comprising the following steps:

[0024] S1. Boil in water: first, powder the heartwood of the balsamic rose, put it in a cloth bag for boiling, and boil for 4 minutes;

[0025] S2. Fermentation: After boiling, keep the heartwood of Dalbergia in water, add 2mg of thiadidiazuron, 1mg of ethephon and 20μmol of methyl jasmonate to each liter of fermentation broth to carry out soaking and fermentation; first lower the temperature to 50-60°C for 3 hours, then ferment Ferment at 30-37°C for 1 day, then at 28°C for 1 day;

[0026] S3. Distillation: Finally, the volatile oil is extracted by the water separation method. Before the extraction, the weight ratio of the heartwood of the balm and water is 1:3, and the extraction is repeated 3 times, each time for 6 hours, to obtain the volatile oil of the balm.

Embodiment 2

[0028] A kind of efficient and swift method for extracting the volatile oil of dalbergia, comprising the following steps:

[0029] S1. Boil in water: Firstly, powder the heartwood of Dalbergia basilica, put it in a cloth bag for boiling, and boil for 6 minutes;

[0030] S2. Fermentation: After boiling, keep the heartwood of Dalbergia in water, add 10mg of thiadidiazuron, 10mg of ethephon and 100μmol of methyl jasmonate to each liter of fermentation broth, and carry out soaking and fermentation; first lower the temperature to 50-60°C for 12 hours, and then Ferment at 30-37°C for 3 days, then at 28°C for 3 days;

[0031] S3. Distillation: Finally, the volatile oil is extracted by the water separation method. Before the extraction, the weight ratio of the balm balm heartwood to water is 1:10, and the extraction is repeated 3 times for 6 hours each time to obtain the balm balm volatile oil.

Embodiment 3

[0033] A kind of efficient and swift method for extracting the volatile oil of dalbergia, comprising the following steps:

[0034] S1. Boil in water: Firstly, powder the heartwood of Dalbergia basilica, put it in a cloth bag for boiling, and boil for 5 minutes;

[0035] S2. Fermentation: After boiling, keep the heartwood of Dalbergia in water, add 4 mg of thiadidiazuron, 5 mg of ethephon, and 80 μmol of methyl jasmonate into each liter of fermentation broth, and carry out soaking and fermentation; first lower the temperature to 50-60 ° C for 6 hours, and then Ferment at 30-37°C for 2 days, then at 28°C for 2 days;

[0036] S3. Distillation: Finally, the volatile oil is extracted by the water separation method. Before the extraction, the weight ratio of the heartwood of the balm and water is 1:5, and the extraction is repeated 3 times, each time for 6 hours, to obtain the volatile oil of the balm.

Abstract

The invention provides an efficient and rapid lignum dalbergiae odoriferae essential oil extracting method. The method includes the steps of S1, conducting water boiling, wherein lignum dalbergiae odoriferae heartwood is pulverized into powder, and the powder is placed in a cloth bag to be boiled in water; S2, conducting fermenting, wherein after water boiling, the lignum dalbergiae odoriferae heartwood is kept in water for soaking and fermenting, fermenting is conducted for 3-12 h after the temperature is lowered to 50-60 DEG C, fermenting is conducted for 1-3 h after the temperature is lowered to 30-37 DEG C, and then fermenting is conducted for 1-3 h at the temperature of 28 DEG C; S3, conducting distilling, wherein the lignum dalbergiae odoriferae essential oil is extracted through a waterproof distilling method for 6 h or longer. The lignum dalbergiae odoriferae essential oil prepared through the method is high in yield, the extraction yield is increased by 35% or above, the content of active components is high, especially the content of trans-nerolidol is remarkably increased, it is shown that the yield and quality of the lignum dalbergiae odoriferae essential oil are remarkably increased by means of the extracting method, and the essential oil has higher value.

Description

technical field [0001] The invention relates to the technical field of balm, in particular to an efficient and quick method for extracting volatile oil of balm. Background technique [0002] The heartwood of Dalbergia is the dry heartwood of the trunk and root of the leguminous plant Dalbergia, mainly produced in Hainan, Guangdong, Guangxi, Yunnan and other places. It has the effects of removing blood stasis, stopping bleeding, regulating qi and relieving pain. It is used for abdominal pain, liver depression and hypochondriac pain , Chest obstruction tingling etc., its main active ingredient is volatile oil and flavonoid compound, wherein the main ingredient of balm oil is trans-nerolidol. Dalbergia oil is often used as a raw material to prepare "Guanxin Danshen Dropping Pills", "Guanxin Danshen Tablets" and "Shuangxiangyou Soft Capsules", and is widely used in the treatment of coronary heart disease clinically. Commonly used methods for extracting balsamic volatile oil inc...
