Embodiment 1
[0046] Example 1 Preparation of the volatile oil of Akiras sinensis
[0047] Take 20kg of dried Tibetan woody medicinal material, crush it properly, put it into a volatile oil extractor, soak it with 10 times the amount of water for 1 hour, then heat and reflux for extraction for 4 hours, let it stand for 1 hour, and dehydrate it with anhydrous sodium sulfate to get Tibetan wood Aroma volatile oil 170ml, relative density 0.803g / ml at 25°C. GC (Gas Chromatography) method measures wherein the total content of inulin and isoinulin is 47.3%.
Embodiment 2
[0048] Example 2 Preparation of the volatile oil of Akiras sinensis
[0049] Take 20kg of dried Tibetan woody medicinal material, crush it properly, put it into a volatile oil extractor, soak it with 10 times the amount of water for 1 hour, then heat and reflux for extraction for 4 hours, let it stand for 1 hour, and dehydrate it with anhydrous sodium sulfate to get Tibetan wood Fragrance total volatile oil 185ml, relative density 0.810g / ml at 25°C. The total content of inulatin and isoinulalide was 18.5% as measured by GC method.
[0050] Take 50ml of the crude extract of volatile oil of Akira sinensis, take 500g of alumina (100-200 mesh), put it into a glass chromatography column by dry method, put the obtained crude extract of : Ethyl acetate (2:1) was used as the eluent for elution. Combine desired fractions. The solvent was recovered under reduced pressure to obtain 23 g of volatile oil of Zangxiang. The sum of the content of inulin and the content of isocusolide is 3...
Embodiment 3
[0051] Example 3 Preparation of the volatile oil of Akiras sinensis
[0052] Take 50ml of the crude extract of the volatile oil of Akiras sinensis in Example 2, take 500g of silica gel (100-200 mesh), and dry-process it into a glass chromatography column, and put the crude extract of Akiras sinensis obtained on the installed silica gel column, The eluent was eluted with petroleum ether: ethyl acetate (10:1). Combine desired fractions. The solvent was recovered under reduced pressure to obtain 10 g of the volatile oil of Zangxiang. The sum of the contents of inulin and isocusolide is 63.0%.
