Comparative identification studies on wild and cultivated Glycyrrhiza uralensis produced Ningxia based on index components and near-infrared spectroscopy
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 identifica-tion based on index components and near-infrared spectroscopy identification.HPLC and UV methods were used to determine the con-tent 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.
