Embodiment 1

[0017] Take 100g of roses, put them 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, the water layer was removed, and the petroleum powder was evaporated at 40°C to obtain pure rose flower extract with a yield of 0.89%.

Embodiment 2

[0019] Take 100g of roses, put them 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, the water layer was removed, and the petroleum powder was evaporated at 40°C to obtain pure rose flower extract with a yield of 0.91%.

Embodiment 3

[0021] Take 150g of roses, put them 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, the water layer was removed, and the petroleum powder was evaporated at 40°C to obtain pure rose flower extract with a yield of 0.94%.

Abstract

The invention relates to an extraction method of a rose extract. The method comprises the following treatment steps: taking 100-150 g of roses, putting the roses into a 2000 mL round-bottom flask, adding 1000-1500 mL of water, putting the flask on a volatile oil extraction device, carrying out reflux extraction for 4-5 h, collecting volatile oil, adding 5-6 mL of petroleum ether into the collectedvolatile oil, slightly shaking, standing, layering oil and water, removing the water layer, and evaporating at 40-50 DEG C to remove petroleum ether so as to obtain the pure rose extract. Compared with the traditional method, the method of the invention has the advantages of simple operation, sufficient color, aroma and taste retention, low pesticide residue and no pollution.

Description

technical field [0001] The invention relates to a method for extracting rose extracts, and belongs to the technical field of extraction and separation of active ingredients 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] Rose flower extract is a general term for various processed rose bud extracts. According to different extraction processes and emphases, extracts with different functional components and contents can be extracted. [0004] Rose flo...
