Abstract

The invention discloses an efficient extraction method and application of sunflower disc volatile oil. The invention belongs to the field of plant extraction. The invention aims to solve the technical problem of low extraction rate of the existing sunflower disc volatile oil extraction process. The method comprises the following steps: drying sunflower discs, crushing and sieving; performing ultrasonic treatment by taking a sodium chloride aqueous solution as an extracting agent; and finally, carrying out water distillation extraction in an extractor to obtain the sunflower disc volatile oil. The obtained sunflower disc volatile oil is used for preparing antioxidant drugs and food antioxidants or treating hyperuricemia. According to the method, the liquid-material ratio and the distillation time are reasonably set, and a proper amount of inorganic salt is added in the extraction process to achieve synergistic interaction, so that the yield of the sunflower disc volatile oil is increased.

Description

technical field [0001] The invention belongs to the field of plant extraction, and in particular relates to a high-efficiency extraction method and application of sunflower plate volatile oil. Background technique [0002] As one of the main by-products of the sunflower industry, sunflower discs have not been paid enough attention to their edible and medicinal value, as well as the activities of phenols, flavonoids and other substances contained in them, and are often used as firewood or even discarded. It is difficult to be effectively and comprehensively utilized by manufacturers. [0003] The main component of volatile oil is terpenoids, and terpenoids refer to substances containing isoprene (C 5 h 10 ) n Hydrocarbons and their oxygen-containing derivatives, antibacterial is the most prominent physiological activity of terpenoids. [0004] α-pinene: antitussive and expectorant, fungus inhibiting, commonly used to produce insect repellants, spices and turpentine and ot...
