Abstract

The invention discloses a method for determining the content of main active components in Alpinia katsumadai by using ultraviolet spectrophotometry. The method uses ultrasonic waves as an auxiliary tool, and comprises the following steps: sampling, preparing a sample, carrying out solvent and ultrasonic wave assisted extraction, carrying out ultraviolet detection, and calculating the content of the main active components. The method allows the main active components of Alpinia katsumadai to be completely and rapidly extracted and to be determined. The method applying an Alpinia katsumadai ultraviolet spectrophotometry testing system realizes rapid and quantitative detection of the concentrations of main active components comprising alpinetin and cardamonin in the Alpinia katsumadai. The method has the advantages of simple operation, accurate determination result, and difficult interference by other substance components.

Description

technical field

[0001] The invention relates to a method for determining the content of main active components of cardamom, belonging to the field of analytical chemistry, in particular to a related technology for determining the content of main active components of cardamom by ultraviolet spectroscopy. Background technique

[0002] Grasshopper is the dry seed mass of Alpiniakatsumadai Hayata, a plant belonging to the genus Zingiberaceae. It is a commonly used traditional Chinese medicine, mainly produced in Guangdong, Guangxi and Yunnan. It has the functions of drying dampness, strengthening the spleen, warming the stomach and relieving vomiting. Its function is mainly used to treat diseases such as cold-damp internal resistance, fullness and cold pain in the dirty abdomen, vomiting due to heating, and lack of appetite. Cardamom is one of the varieties of Dai medicine, and its rhizome can cure various aches and pains caused by rheumatism. The extract of cardamom has obviou...
