Problems solved by technology

It has a history of 3,000 years of medicinal use in China. At present, there is no method and standard for testing the quality of Artemisia annua. Artemisia annua contains flavones (5,3-dihydroxy-3,7,4-trimethylflavone), Isorhamnoside, Isorhamnoside, Yunxiang, Plant Polysaccharide (Inulin), Artemisia Coumarin, 7-Methoxycoumarin, 7,8-Methylenedioxy-6-Methoxy Dozens of functional ingredients such as base coumarin and organic selenium

Embodiment Construction

[0007] Test methods for total flavonoids of functional ingredients: 1. Instrument: 751G UV-visible photometer, electro-optical analytical balance, Soxhlet extractor; 2. Reagent: rutin standard, methanol, ethanol, sodium nitrite, aluminum phosphate, hydroxide Sodium is AR grade; 3. Determination method:

[0008] Preparation of standard solution Accurately weigh 100mg of rutin reference substance dried under reduced pressure at 120°C to constant weight, put it in a 50ml measuring bottle, add 30ml of methanol, put it on a water bath to slightly heat to dissolve, let it cool, add methanol to dilute to the mark, Shake well. Accurately draw 10ml, put it in a 100ml volumetric flask, add 50% ethanol to dilute to the mark, shake well, and obtain (every 1ml contains 0.2mg of anhydrous rutin).

[0009] Preparation of standard curve Precisely draw standard solutions 1.0, 2.0, 3.0, 4.0, 5.0 and 6.0ml, put them in 25ml volumetric flasks respectively, add 6ml of 50% ethanol and 1ml o...

Abstract

A quality standard for medical artemisia pig weed is disclosed. Its verifying method includes examining appearance by visual observation, measuring water content by fast driver, testing general flavone by ultraviolet spectrophotometry, measuring soluble plant polyose by acid hydrolyzing for 10 min and iodometry, and testing organoselenium, organozinc and heavy metals (Hg, Pb and As) by atomic absorption spectrametry. Its advantage is high correctness.

Description

[technical field] [0001] The invention relates to a quality inspection method and standard for medicinal Artemisia arvensis. [Background technique] [0002] Artemisia Selengeusis Turez, a wild plant with both medicine and food. The place of origin is the grassland on the shore of Poyang Lake. It has a history of 3,000 years of medicinal use in China. At present, there is no method and standard for testing the quality of Artemisia annua. Artemisia annua contains flavones (5,3-dihydroxy-3,7,4-trimethylflavone), Isorhamnoside, Isorhamnoside, Yunxiang, Plant Polysaccharide (Inulin), Artemisia Coumarin, 7-Methoxycoumarin, 7,8-Methylenedioxy-6-Methoxy Dozens of functional ingredients such as base coumarin and organic selenium. These physiologically active substances can be made into various medicines and health-care functional foods from Artemisia quinoa. For the medicinal development of Artemisia arvensis, quality inspection methods and standards for medicinal Artemisia arbor...
