Extraction method of indocalamus leaf volatile oil

Abstract

The invention relates to an extraction method of an indocalamus leaf volatile oil, and belongs to the field of plant volatile oil extraction. The extraction method comprises the processing steps: fermenting an indocalamus leaf powder by cellulase; after fermentation, extracting the raw material by an ultrasonic-microwave method; and leaching the extraction liquid with an organic solvent, drying with anhydrous sodium sulfate, carrying out reduced pressure concentration and other steps, and thus obtaining the indocalamus leaf volatile oil. The extraction method has the advantages of simple process, small energy consumption, mild reaction conditions, and high yield of the product, and overcomes the shortcomings that a traditional steam distillation method wastes time and energy and a product is easy to lose.

Description

technical field [0001] The invention relates to a method for extracting volatile oil from leaves of Ruo bamboo leaves, in particular to a method for assisting extraction of volatile oil from leaves of Ruo bamboo leaves by enzyme fermentation combined with an ultrasonic-microwave method. Background technique [0002] Ruozhu leaves, commonly known as zongye, are the leaves of broad-leaved Ruozhu in the genus Ruozhu in the subfamily Bambooaceae of Gramineae. It is mainly used to treat sore throat, pulmonary abscess, nosebleeds, menstruation, intestinal wind and blood in the stool, urinary obstruction, and for women to promote lactation, etc. The unique zongzi fragrance of Ruozhu leaves is a pleasant natural fragrance, which meets the requirements of modern people to return to nature. Therefore, the volatile oil extracted from Ruo bamboo leaves will have broad application prospects in the development fields of products such as natural essence, food additives, cosmetics, deodora...

AI Technical Summary

Problems solved by technology

The steam distillation method has high extraction temperature and long time, which is easy to change the volatile components that are unstable to humidity and heat, and the components with high boiling points are difficult to detect; while the supercritical fluid extraction method is a new extraction method, which has a strong ability to extract volatile oils , has the advantages of preventing oxidation, pyrolysis and improving the quality of volatile oil, but this process requires high-pressure equipment, high technical requirements, large investment in equipment costs, and is not widely used
