Abstract

The invention discloses a method for extracting flavonoid substances in penthorum chinense pursh. The method comprises the steps that (1), the penthorum chinense pursh is smashed into fine powder withthe particle size of being 40 mesh or above; (2), the fine powder is dried for 4-6 hours at the temperature of 60-80 DEG C; (3), a methyl alcohol solution is added, a nanometer metal material is added, micro waves are applied, after uniform mixing, water-bath extraction is conducted for 1.5 hours at the extraction temperature of 60-80 DEG C by using a refluxing device, and then the mixture is taken out and subjected to vacuum filtration to obtain filter liquor; (4), pretreated polyamide resin and macroporous resin are weighed, the filter liquor obtained in the step 3 is added to obtain a mixture, the mixture is placed into an oscillator for oscillation for 12 hours at the temperature of 30 DEG C, elution is conducted by using a solvent, an eluant is collected, concentrated and evaporatedto dryness, and then the extracts are obtained.

Description

technical field [0001] The invention relates to the field of extracting effective components of C. chinensis, in particular to a method for extracting flavonoids in C. sativa. Background technique [0002] Chamomile, also known as root vegetable, water willow (Sichuan), and water Zelan (Guizhou), is a kind of plant of the genus Rhizoma subfamily of Saxifragaceae Rhizoma subfamily, and is a perennial herb. It was first recorded in "Rescue Famine Materia Medica" in the Ming Dynasty, and it is also recorded in "Dictionary of Chinese Medicine", "National Chinese Herbal Medicine Collection", "Sichuan Traditional Chinese Medicine", "Hunan Medicine", and "Inner Mongolia Plant Medicine". There are many places where yellow grass grows, mainly in Yunnan, Guizhou, Sichuan, Guangdong and Guangxi, Hebei, Gansu, Hunan, and Jiangxi; abroad, it is mainly distributed in South Korea, Japan, Mongolia, Russia, Thailand, Vietnam, etc., among which Gulin, Sichuan Province The county's altitude i...
