Alkaloids in Processed Rhizoma Corydalis and Crude Rhizoma Corydalis Analyzed by GC/MS
Total ion current chromatograms of RC. S1: processed RC sample extracted with methanol, S2: crude RC sample extracted with methanol, and S3: crude RC sample extracted with acetone. (a) The total chromatogram and (b) the enlarged chromatogram after 19 min. The peak number is consistent with Table 1. 4# and 5# (+)-corydaline. Column: HP-5-MS column, injector temperature: C, GC oven temperature program: 40°C (does not hold), at 40°C/min to 110°C (does not hold), at 8°C/min to 260°C (holds for 10 min).
