近红外光谱法快速测定晒青毛茶三种儿茶素组分含量OACSTPCD
Rapid Determination of Three Catechin Components in Crude Pu-erh Tea by Near Infrared Spectroscopy
为了实现晒青毛茶儿茶素含量的快速检测,该研究利用高效液相色谱技术(High Performance Liquid Chromatography,HPLC)测定了 50 份晒青毛茶样品中的表没食子茶素没食子酸酯(Epigallocatechin Gallate,EGCG)、表没食子儿茶素(Epigallocatechin,EGC)、没食子酸(Gallic Acid,GA)三种儿茶素单体含量,结合样品的近红外光谱,分别建立了晒青毛茶三种儿茶素单体含量…查看全部>>
In order to achieve rapid detection of the catechin content in crude Pu-erh tea,high performance liquid chromatography(HPLC)was used to determine the contents of three catechin monomers,namely,epigallocatechin gallate(EGCG),epigallocatechin(EGC),and gallic acid(GA),in 50 crude Pu-erh tea samples,and the partial least squares models(PLS)were also established to predict the contents of these catechins by combining the near infrared spectra(NIRS)of the samples.…查看全部>>
