Recovery
SD
Mean extraction recovery for each analyte and IS in plasma and urine is summarized in Table Mean extraction recovery, matrix effect, and hemolyzed plasma effect for andrographolide (AP1); 14-deoxy-11, 12-didehydroandrographolide (AP3); neoandrographolide (AP4); and 14-deoxyandrographolide (AP6) in plasma (a) and in urine (b) samples.Data expressed as mean ± SD, (n = 5).Low quality control concentration (LQC concentration), medium quality control concentration (MQC concentration), high quality control concentration (HQC concentration).
