Embodiment 1
[0060] Extraction and purification of volatile oil
[0061] Take 50 grams of forsythia, 50 grams of green peel, 200 grams of tangerine peel, 50 grams of Huoxiang, 200 grams of star anise, 100 grams of woody fragrance, 100 grams of clove, 50 grams of cumin, 100 grams of Chuanxiong, 100 grams of Angelica dahurica, a total of 1kg of Chinese medicinal materials , grind into fine powder, add to a 20L flask, add 10L of distilled water, and mix well. A Soxhlet extractor is connected to a spherical condenser, and an electric heating mantle is used to heat the flask to boil the water, and the water vapor is evaporated with volatile oil, and the extract is refluxed in the Soxhlet extractor until there is no oil, and the extraction lasts for nearly 3 days. What volatilizes first is white clear oil, and as time goes on, the color deepens until dark yellow, that is, heavy oil. After the extraction is complete, put the obtained volatile oil extract in a separatory funnel, add an appropri...

[0063] Extraction and purification of volatile oil
[0064] Take 4 grams of forsythia, 3 grams of green peel, 10 grams of tangerine peel, 4 grams of Huoxiang, 14 grams of star anise, 7 grams of woody fragrance, 6 grams of clove, 4 grams of cumin, 6 grams of Chuanxiong, and 7 grams of Angelica dahurica. 65g, grind into fine powder, add to 1000mL flask, add 500mL of distilled water, mix well. A Soxhlet extractor is connected to a spherical condenser, and an electric heating mantle is used to heat the flask to boil the water. The water vapor is evaporated with volatile oil, and the Soxhlet extractor is refluxed until there is no oil. After the extraction is complete, put the obtained volatile oil extract in a separatory funnel, add an appropriate amount of ether, shake slowly toward the direction of no one, release air in time, and finally separate the liquid, and dissolve the volatile oil in ether. The diethyl ether dissolved in the volatile oil was placed in a 100mL flask, c...

[0069] Extraction and purification of volatile oil
[0070] Take 7g each of forsythia, green peel, tangerine peel, Huoxiang, star anise, woody, clove, cumin, Chuanxiong, Baizhi and other traditional Chinese medicinal materials, totaling 70g, grind into fine powder, add to a 1L flask, add 600mL of distilled water, mix uniform. A Soxhlet extractor is connected to a spherical condenser, and an electric heating mantle is used to heat the flask to boil the water. The water vapor is evaporated with volatile oil, and the Soxhlet extractor is refluxed until there is no oil. After the extraction is complete, put the obtained volatile oil extract in a separatory funnel, add an appropriate amount of ether, shake slowly toward the direction of no one, release air in time, and finally separate the liquid, and dissolve the volatile oil in ether. The diethyl ether dissolved in the volatile oil was placed in a 250mL flask, concentrated by a rotary evaporator for 12min, and finally about 6m...
