Abstract

The invention discloses a method for separating and extracting essential oil from ocimum gratissimum. The method includes: taking the overground part of the ocimum gratissimum prior to cleaning and airing, and mixing smashed ocimum gratissimum powder with kieselguhr according to the mass ratio of 1:(1-3) to obtain a mixed sample; adding 2-4 times of chloroform into the mixed sample, extracting and filtering to obtain filtrate and residues; subjecting the residues to accelerated solvent extraction to obtain an extracting solution, and performing filtration to obtain the filtrate; adding equivoluminal steamed water into the filtrate, adequately mixing and standing for extraction; separating out the part insoluble in water, and performing vacuum concentration to obtain the product. The extraction rate of the method is more than 22% higher than that of a traditional extraction method, and the method is simple in operation and easy to implement, sufficient in extraction, high in raw material and reagent utilization and suitable for industrial production.

Description

technical field [0001] The invention relates to the field of biochemical industry and biological extraction. More specifically, it relates to a method for separating and extracting essential oil from clove basil. Background technique [0002] Clove basil is an erect annual herb commonly grown in large quantities as a medicinal and spice. It can be used to treat bacterial infection, diarrhea or as a flavoring agent, and has the functions of antifungal, antimutagenic, antibacterial, immune regulation and control of smooth muscle contraction. Due to the wide application of basil in traditional medicine and its medical effects, more and more researches have been done on its composition, function and mechanism of action in recent years. [0003] Basil essential oil has analgesic and calming effects, and can quickly treat toothache, digestive problems, muscle pain, asthma, sinusitis and other diseases. In addition, basil essential oil also has antiseptic and antibacterial abili...
