Abstract

The invention discloses a method for extracting gynostemma pentaphylla seed oil through ultrasonic wave. The method comprises the following steps: peeling gynostemma pentaphylla fruit, picking seeds and then cleaning the seeds, drying, grinding and then filtering by a screen with 65 meshes, weighing powder, taking petroleum ether with the boiling range from 30 to 60 DEG C as extracting solution, and fully shaking up and then extracting under the ultrasonic condition. The method has the advantages that the extracting time is short, the solvent dosage is small, the extracting efficiency is high, the solvent recovering rate is high, the quality of the seed oil is good, the cost is low, and the investment is small.

Description

technical field [0001] The invention relates to the technical field of vegetable oil extraction, in particular to a method for ultrasonically extracting Gynostemma pentaphyllum seed oil. Background technique [0002] Vegetable oil is a natural compound composed of fatty acid and glycerol, which is widely distributed in nature, and its physicochemical properties and functions mainly depend on the type and distribution of the mixed fatty acids that make it up. Among natural vegetable oils and fats, oleic acid and linoleic acid are the most abundant, and the types and contents of fatty acids vary greatly among different types of plant resources. Vegetable oil is an important source of essential fatty acids. In order to meet the needs of the human body, it should not be less than 50% of the total fat source in the diet, otherwise it will easily lead to dysplasia, skin abnormalities, poor immunity, and even low fertility. Vegetable oils and fats contain more unsaturated fatty ac...
