Antirheumatoid Arthritis Activities and Chemical Compositions of Phenolic Compounds-Rich Fraction from Urtica atrichocaulis, an Endemic Plant to China

Figure 3

HPLC profile of phenolic compounds-rich fraction from Urtica atrichocaulis (TFUA). The concentration of TFUA was 1.0 mg/mL and injection volume was 10 μL. The detection wavelength was set at 280 nm and the column was thermostated at 30°C. The eluent was H2O (containing 0.1% acetic acid)/acetonitrile. A linear gradient solvent system was used, starting from 95% H2O to 100% acetonitrile during a 40-min period, at the flow rate of 0.8 mL/min. 1: protocatechuic aldehyde; 2: caffeic acid; 3: chlorogenic acid; 4: secoisolariciresinol; 5: rutin; 6: phaselic acid; 7: kaempferol-3-O-rutinoside + kaempferol 3, 7-di-O-rhamnopyranoside; 8: salicylic acid; 9: scopoletin; 10: ferulic acid + gossypetin; 11: quercetin; 12: luteolin.
