Abstract:
AIM To screen anti-inflammatory activity Q-markers for Glycyrrhizae Radix et Rhizoma.METHODS Lipopolysaccharide was used for stimulating RAW264.7 macrophages to establish inflammatory model,after which the NO inhibitory rates of different grades of medicinal materials were determined.The UHPLC-QTOF-MS fingerprints were established,after which chemical constituents were identified,heatmap was drawn,and orthogonal partial least squares analysis was performed.RESULTS Grade 1 and grade 2 medicinal materials demonstrated higher NO inhibitory rates than gradeless and uniformly-priced goods(P＜0.05,P＜0.01).There were 211 common peaks in the fingerprints of 47 batches of medicinal materials,total 56 compounds were identified,containing 17 saponins,6 flavonoids,8 flavanones,4 chalcones,12 isoflavones and 9 other kinds.The relative contents of isoflavones,coumarins,kaempferol and licoflavonol in grade 1 and grade 2 medicinal materials were higher than those in gradeless and uniformly-priced goods,while the relative contents of flavanones,chalcones and saponins in wild products were higher than those in cultivated products.Neoliquiritin,isoliquiritin,kaempferol,hedysarimcoumestan E,licorice saponin C2,licoarylcoumarin,glicoricone and liconeolignan were taken as Q-markers.CONCLUSION This stable and reliable method has a certain reference value for the quality control of Glycyrrhizae Radix et Rhizoma.
