Objective To establish optimum processing method for Pollen Typhae Carbonisatus. Method Processing method was studied by orthogonal test and the total flavones were determined by HPLC. Conditions of HPLC used to determine the total flavones were: Waters Nove-Park C18 (150 mm?3.9 mm, 4 ?m), mobile phase: MeOH-THF-0.05%TFT (16∶24∶60), flow rate: 0.8 mL/min, column temperature: 30 ℃, detection wavelength: 360 nm. Results The optimum processing method was skir-baked for 8 min at 210 ℃. Conclusion The optimized processing method is available for the processing of Pollen Typhae Carbonisatus.

Objective To identify the drug-induced constituents in rat serum containing drug of Compound Wurenchun Capsula and determine the content of these constituents. Methods Identification of the drug-induced constituents in serum has been carried out by combinative method of HPLC-DAD and UPLC-MS/MS. The content of four lignans in serum has been detected by HPLC-UV. Results Seven of eight original form compounds in serum have been identified as schisandrin,gomisin J,schisandrol B,deoxyschizandrin,gomisin N,schisandrin B,and schisandrin C. The UV spectrogram of five metabolites showed the absorption character of dibenzocyclooctadiene lignans. Eight lignans were identified by UPLC-MS/MS,besides schisantherin,there are seven lignan-like ones detected by HPLC-DAD.
