Abstract

The invention relates to a method for measuring the luteolin content. The chromatographic conditions of the method are as follows: packed column is octadecyl silane chemically bonded silica, the mobile phase is an acetonitrile-phosphoric acid solution, the flowing speed of the mobile phase is 1.0 mL/min, the column temperature is 20 to 40 DEG C, the detection wavelength is 250 to 350 nm, and the sample size is 20 [mu]L. The measuring result of the method is accurate and reliable, and the method is convenient and scientific, meets the requirements of Chinese pharmacopoeia, and has good detection results.

Description

technical field [0001] The invention belongs to a method for detecting drug content, in particular to a method for measuring luteolin content. Background technique [0002] Luteolin (luteolin) is a kind of natural flavonoids, which exists in various plants such as whole-leaf green orchid, pepper, wild chrysanthemum, honeysuckle, perilla and so on. It has a variety of pharmacological activities, such as anti-inflammatory, anti-allergic, anti-tumor, anti-bacterial, anti-viral, etc. Among them, the antitussive and expectorant effects are the most significant. It is mainly used clinically for cough, expectorant, anti-inflammatory, cardiovascular disease, and " Amyotrophic lateral sclerosis", SARS, hepatitis, etc. The purified luteolin is a yellow needle crystal with a melting point of 328-330°C. Slightly soluble in water, weakly acidic, soluble in alkaline solution, stable under normal conditions. [0003] Due to the good and broad-spectrum pharmacological effects of luteolin...
