对皋茶中酚类物质进行了不同方法的提取、纯化研究,优选一种方法,以提取纯化的酚类物质作标准品,制作皋茶酚类工作曲线,测定皋茶中酚类的总量。初步确立了酒石酸铁法定量皋茶酚类的换算系数,并对皋茶酚类进行了光谱性质研究。
The method of extraction and purification of phenolic compounds in wolfberry tea by different methods is preferred. A method is used to extract purified phenolic substances as standards, and a working curve of catechol is produced to determine the total amount of phenols in wolfberry tea. . The iron tartrate method was used to quantitatively determine the conversion coefficient of the catechols and the spectral properties of the catechols were studied.
