Problems solved by technology

Humans have smoked marijuana for more than a thousand years, and the special aroma of marijuana mainly comes from terpenes. The terpenes in marijuana can be used as spices in cigarettes and food flavors, and have extremely high economic value; but its Strong volatility. At present, when preparing other active substances (such as cannabinoids), terpenes are often directly discharged, resulting in a great waste of resources

Abstract

The invention provides a method for extracting volatile oil from cannabis sativa and an application of the volatile oil, and by adopting the method, the technical defect that the volatile oil components of the cannabis sativa are not utilized and are discharged together with waste gas in the prior art can be overcome. The invention provides the method for extracting volatile oil from cannabis sativa, and the method comprises the following steps: 1) drying and dehydrating cannabis sativa flower leaves; 2) grinding the dried and dehydrated hemp flowers and leaves in the step 1) into powder, andremoving hemp seeds in the hemp flowers and leaves; 3) putting the hemp flower and leaf material treated in the step 2) into a heating and drying device; wherein an air outlet of the heating and drying device is connected with a condensing device, and the condensing device is used for condensing gas exhausted from the air outlet to obtain condensate containing volatile oil; 4) extracting the condensate obtained in the step 3) with an extracting agent and taking a supernatant, and 5) washing the supernatant obtained in the step 4) with water and removing a water layer, and distilling an obtained organic layer.

Description

technical field [0001] The invention relates to the fields of tobacco and food, in particular to a method for extracting volatile oil from cannabis. Background technique [0002] The chemical composition of industrial hemp is very complex, mainly including lipids, flavonoids, terpenes, hydrocarbons, non-cyclic large phenols, alkaloids, silver citrate and cyclic cannabinol, etc. Humans have smoked marijuana for more than a thousand years, and the special aroma of marijuana mainly comes from terpenes. The terpenes in marijuana can be used as spices in cigarettes and food flavors, and have extremely high economic value; but its Volatility is strong, currently when preparing other active substances (such as cannabinoids), terpenes are often directly discharged, resulting in a great waste of resources. Contents of the invention [0003] In view of this, the present invention provides a method for extracting volatile oil from marijuana, adopting the method of the present invent...
