Comparative identification studies on wild and cultivated Glycyrrhiza uralensis produced Ningxia based on index components and near-infrared spectroscopy / 中国中药杂志

ABSTRACT

This study is to construct a rapid and effective method for identification of wild and cultivated Glycyrrhiza uralensis (hereinafter referred to as Glycyrrhizae Radix et Rhizoma) from Ningxia by comparison of the difference in chromatography identification based on index components and near-infrared spectroscopy identification. HPLC and UV methods were used to determine the content of liquiritin, glycyrrhizate and total flavonoids for 9 wild Glycyrrhizae Radix et Rhizoma and 14 cultivated Glycyrrhizae Radix et Rhizoma samples,and the near-infrared spectroscopy was also,collected. The results illustrated that the chromatography identification based on index components could not identify wild and cultivated Glycyrrhizae Radix et Rhizoma from Ningxia, while near-infrared spectroscopy could quickly and effectively achieve it. It provides an effective method for the growth pattern identification and application of Glycyrrhizae Radix et Rhizoma.
