Embodiment 1

[0016] Take 100g of clove powder, put it in a 2000mL round bottom flask, add 1000mL of water. Put it on the volatile oil extraction device for reflux extraction for 4 hours, and collect the volatile oil. Add 5 mL of petroleum fans to the collected volatile oil and shake slightly. After resting, the oil-water layer was separated, and the water layer was removed, and the petroleum powder was evaporated at 40°C to obtain pure clove oil with a yield of 0.67%.

Embodiment 2

[0018] Take 100g of clove powder, put it in a 2000mL round bottom flask, add 1000mL of water. Put it on the volatile oil extraction device for reflux extraction for 5 hours, and collect the volatile oil. Add 6mL of petroleum fans to the collected volatile oil and shake slightly. After resting, the oil-water layer was separated, and the water layer was removed, and the petroleum powder was evaporated at 40°C to obtain pure clove oil with a yield of 0.69%.

Embodiment 3

[0020] Take 150g of clove powder, put it in a 2000mL round bottom flask, add 1500mL of water. Put it on the volatile oil extraction device for reflux extraction for 5 hours, and collect the volatile oil. Add 6mL of petroleum fans to the collected volatile oil and shake slightly. After resting, the oil-water layer was separated, and the water layer was removed, and the petroleum powder was evaporated at 40°C to obtain pure clove oil with a yield of 0.72%.

Abstract

The invention relates to an extraction method of clove oil. The treatment method comprises the following steps: putting 100-150 g of clove powder into a 2000-ml round-bottom flask, adding 1000-1500 mlof water, placing the round-bottom flask onto a volatile oil extracting device, carrying out reflux extraction for 4-5 hours, collecting volatile oil, adding 5-6 ml of petroleum ether into the collected volatile oil, carrying out slight vibration, carrying out standing, then carrying out oil-water layering, removing the water layer, and evaporating out the petroleum ether at 40-50 DEG C to obtainthe pure clove oil. Compared with a conventional method, the method has the advantages that operation is simple, full color and fragrance are preserved, the pesticide residue amount is low, and no pollution is caused.

Description

technical field [0001] The invention relates to a method for extracting clove oil, which belongs to the technical field of extraction and separation of effective components of natural products. Background technique [0002] Volatile oils, also known as essential oils, are a general term for a class of volatile oily components present in plants that have an aromatic odor, can be distilled with water vapor, and are immiscible with water. Volatile oil is a mixture with complex components. The traditional method is mainly to produce essential oil through steam distillation and pressing. Among the volatile oil components, terpenes are more common. In addition, they also contain small molecular aliphatic compounds, which are mostly aromatic. [0003] Cloves can be used for cooking, cigarette additives, incense additives, tea making, etc. It can also be used as medicine. In traditional Chinese medicine, clove buds are also used as medicine. The drug name is Gonglixiang, which is ...
