Abstract

The invention relates to an extraction method of dogwood kernel oil and effectively solves the problem in extracting dogwood kernel oil. The method comprises the following steps of: grinding the dogwood kernel and adding into an extractor; injecting the solvent into the extractor; adding the same solvent into a distiller; heating until boiling, and keeping the boiling state; condensing the steam into liquid by a condenser, and spraying the liquid into the extractor; percolating; enabling the liquid in the extractor to flow back to the distiller from a lower exit of the extractor through a siphon pipe, and heating by the distiller for distillation; cooling the steam into liquid by the condenser and feeding the liquid into the extractor again; when the liquid from the extractor is colorless and oil cannot be detected in the liquid, recycling the solvent, wherein when no liquid flows out of the condenser, the residual liquid in the distiller is the crude dogwood kernel oil; and treating the crude dogwood kernel oil by a conventional vegetable oil refining method to obtain the dogwood kernel oil. According to the invention, the aim of extracting crude oil from the dogwood kernel can be achieved by use of simple equipment and a set of operation procedure easy to master and by consuming little solvent and energy.

Description

technical field [0001] The invention relates to a method for extracting cornel seed oil. Background technique [0002] Dogwood grows in bushes on hillsides and is mainly distributed in Shanxi, Shaanxi, Shandong, Anhui, Zhejiang, Henan, Sichuan and other provinces. Its peel (pulp) is a kind of tonic and health medicine that has the functions of nourishing the liver and kidney, astringent essence and detoxification. However, the fruit stone, which accounts for about 80% of the weight of the fruit of Cornus officinalis, has been abandoned as waste for a long time; The situation of fruit stones has been seldom reported for a long time. In order to develop and utilize the rich resource of Cornus officinalis, many years of painstaking research on its chemical composition and pharmacological activity; Antibacterial, anti-inflammatory, anti-oxidant, hypoglycemic, anti-cancer, whitening and anti-platelet aggregation and other pharmacological activities of meat nucleus control test)...
