在稀碱液中茯苓聚糖与百里酚—硫酸反应生成有色物质,在波长为505±2nm处可测定出茯苓中茯苓聚糖的含量,本方法简便、快速、准确。
In the dilute alkaline solution, the sulphate reacts with thymol-sulfuric acid to form a colored substance. The content of sulphocan in the sorghum can be determined at a wavelength of 505±2 nm. This method is simple, rapid, and accurate.
