The flow rate was 1.0 mL/min. The column temperature was 30 ℃ and the detection wavelengths were 203 nm and 237 nm, respectively. The linear ranges were 0.700,0—7.000,0 μg for R1(r=1.000,0), 0.751,1— 7.511,4 μg for Rg1(r=1.000,0), 0.677,2—6.771,6 μg for Re(r=1.000,0), 0.733,9—7.339,1 μg for Rb1(r= 1.000,0), and 0.540,0—5.399,8 μg for ammonium glycyrrhizinate(r=0.999,9), respectively. In addition, their average recoveries were 100.28%, 105.83%, 104.09%, 99.36% and 98.54%, respectively. The relative standard deviations(RSDs) of precision, reproducibility and recovery were all less than 1.5%. The results indicate that the method is simple, accurate and reproducible so that it can be used for the simultaneous determination of the five saponins in Chinese patent medicines containing the three kinds of herbs.展开更多

Methods： Fivedatabases （CNKI, VIP, Wanfang data, CBM, and Pubmed） were used to search for studies on the chemical structure ofcompounds from GC. The retrieval time of the respective databases was from their inception to March 2016. Accordingto the inclusion and exclusion criteria, the papers were carefully screened, and the data were extracted. Results： A totalof 653 compounds from GC were collated from 252 articles, including flavonols （n = 201） belonging to 10 subgroups,terpenes and saponins （n = 167）, coumarins （n = 30） belonging to 3 subgroups, aliphatics （n = 206）, aromatics （n = 35）,and others （n = 14）. The flavones, represented by liquiritin and liquiritigenin, were the most reported compounds isolatedfrom GC, followed by terpenes and saponins such as glycyrrhizic acid and glycyrrhetinic acid. Conclusion： The morethan 600 natural compounds in GC may be responsible for GC’s anti-inflammatory, phlegm-expelling, cough- andpain-relieving activities.展开更多
