Abstract

The invention discloses an extraction method of effective ingredients of winter jasmine. The method comprises the following steps: smashing leaves of thewinter jasmine into nanometer powder, degreasing, drying, processing degreased solid powder with a eutectic reagent by a microwave-ultrasonic technology and filtering, so as to obtain filtrate; finally, adding a certain amount of methanol into the filtrate for vortexcentrifugation, so that an upper phase of methanol is separated; evaporating a solvent, so as to obtain extracts of the effective ingredients of the winter jasmine. With adoption of the extraction method, the effective ingredients of the winter jasmine are extracted by adopting the eutectic reagent through combination of the microwave-ultrasonic technology, so that the leaching content of the effective ingredients can be remarkably improved, the extraction efficiency is improved, the using amount of the organic solvent can be reduced, and the method is environment-friendly. Additionally, according to the method disclosed by the invention, the extraction time can be shortened, and the cost is lowered. The extracts of the winter jasmine, which are obtained by the method, do not need to be purified subsequently and can be directly applied todaily chemicals such as toothpaste, a facial cleanser, body wash, shampoo, hand creamandthe like as a natural antibacterialpreservative.

Description

technical field [0001] The invention relates to a method for extracting and purifying active ingredients in daily chemicals, more specifically, the invention relates to a method for extracting active ingredients of Jasmine japonica. Background technique [0002] Jasminum nudiflorum Lindl., a plant of the genus Jasmine in the family Oleaceae, is widely cultivated in various parts of the Yangtze River Basin, and its flowers and leaves are also common herbal medicines in western Hunan. The leaves are bitter and flat, which can clear away heat and detoxify, stop bleeding, and relieve pain. It is used to treat bruises, traumatic bleeding, stomatitis, gynecological inflammation, carbuncle, furuncle, swelling and itching of the vulva. The flowers are often used as tea. Its taste is sweet, astringent, flat, heat-clearing, diuretic and detoxifying. It can treat headache, fever, urinary system infection and lower extremity ulcers. Modern studies have shown that winter jasmine is rich...
