Embodiment

[0011] Example: Take 1000 grams of stems and leaves of Kidney Tea, dry and pulverize them (20-100 mesh) and put them into an extractor.

[0012] 1. First add 8 times the amount of distilled water, heat to 85°C, extract at a constant temperature for 120 minutes, repeat the extraction three times, collect the extract, concentrate, ethanol precipitation, filter, and dry to obtain 163.0 g of solids, with a yield of 16.3%. This part is the water-soluble compound of kidney tea.

[0013] 2. After water extraction, the material was dried, extracted with 6 times the amount of 70% ethanol, the extraction temperature was 75 ° C, the extraction time was 60 minutes, and the extraction was repeated three times. The ethanol extract was collected, concentrated, and dried to obtain 62.2 grams of solids. The yield was 6.2%. This part is the alcohol-soluble compound of kidney tea.

[0014] 3. After alcohol extraction, the material was dried and extracted with 5 times the amount of ethyl acetat...

Abstract

The invention provides a method for extracting compound from kidney tea stalks and leaves, crushing the stalks and leaves, successively adopting water extraction, alcohol extraction, and ethyl acetate to extract water soluble, alcohol soluble and fat soluble compounds, which are rosemary acid, caffeic acid, bear fruit acid, Yuan er tea acid, isoflavone, rosemary acid acetate and other phenolic compounds and flavone compounds. The invention is a kidney tea compound extracting method, effective and applied to industrial production.

Description

Technical field: [0001] The invention relates to a method for extracting compounds from plants, that is, a method for extracting compounds by using the stems and leaves of kidney tea as raw materials. Background technique: [0002] Kidney tea is the above-ground part of Kidney tea of ​​the Lamiaceae Kidney tea plant, also known as "cat's whiskers", and its whole plant has diuretic, antibacterial, anti-inflammatory, stone-dissolving, and stone-expelling effects. It is mainly used to treat acute and chronic nephritis, urinary tract infection, urinary calculi, pharyngitis and rheumatoid arthritis. Kidney tea stems and leaves contain a variety of chemical components ["Yunnan Botanical Research" 1984, 6(3): 344-345, "Yunnan Botanical Research" 2004, 26(5): 563-568], mainly including rosemary acid, caffeic acid, protocatechuic acid, isocitrurin, ethyl rosmarinate, ursolic acid and other phenolic compounds and flavonoids, among which rosmarinic acid, ursolic acid and flavonoids ar...
