Example Embodiment

[0035]Example 1-6:

[0036]The present invention uses the following methods to extract aromatic oil from wildfire radish plants in the nature reserve:

[0037]Step (1) Raw material collection: Collect wild wild carrot plants from the nature reserve. The plant collection method is shown in Table 1;

[0038]Step (2) Cleaning: Put the wild carrot plants obtained in step (1) into a fruit and vegetable washing machine to wash away impurities such as dust and soil. The cleaning time, temperature, water consumption and other parameters are shown in Table 1;

[0039]Step (3) Chopping: Under certain hypoxia, cut the length of the wild carrot plant perpendicular to or close to the plane where the cutting knife of the cutting machine is located, and cut the wild carrot plant obtained in step 2) with a cutting machine The length of the wild carrot plant is perpendicular to or close to perpendicular to the plane of the cutter of the cutting machine. The parameters of the wild carrot plant segment length and...

Abstract

The invention discloses a method for extracting aromatic oil from wild carrot plants in a natural conservation area, and particularly relates to the field of biological separation of natural products.The method comprises the steps of raw material collection, cleaning, chopping, pre-drying, atmospheric distillation, reduced pressure distillation, distillate purification and the like, and can alsocomprise the steps of solution soaking and the like. According to the method, the aromatic oil is extracted by taking the wild carrots which are foreign invasive species in the natural conservation area as raw materials, so that the harm of the wild carrots to the conservation area is eliminated, valuable aromatic oil can be obtained, and two purposes are achieved; aromatic oil is extracted in ananoxic or anaerobic environment, so that damage to double-bond structures in various organic molecules of the aromatic oil is effectively reduced, and the quality of the aromatic oil is improved; andwhole wild carrot plants can be used as raw materials, and aromatic oil in the wild carrot plants is extracted in a classified manner, so that various components in the aromatic oil are fully utilized.

Description

technical field [0001] The invention relates to the technical field of biological separation of natural products, more specifically, the invention relates to a method for extracting aromatic oil from wild carrot plants in nature reserves. Background technique [0002] Wild carrot is a biennial herbaceous plant with a plant height of 15-120 cm. It is distributed in Sichuan, Guizhou, Hubei, Jiangxi, Anhui, Jiangsu, Zhejiang and other provinces in China. It often grows on hillsides, roadsides, wilderness or fields. Wild carrot has high medicinal value, and its fruit can be used as medicine, which has a dilating effect on coronary arteries; it can also extract aromatic oil. [0003] However, wild carrot is a kind of alien invasive plant in the nature reserve. It shows a tendency of accelerating spread in the reserve. It is the most widely distributed species among all invasive species. The number of wild carrots per unit area (1㎡) can reach dozens of plants , there is a tendenc...
