SD
The %CV for intra-day and inter-day precision of each analyte in plasma sample (Table The intra-day and inter-day accuracy and precision of four major diterpenoids: 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).Lower limit of quantitation (LLOQ).Low quality control concentration (LQC concentration), medium quality control concentration (MQC concentration), high quality control concentration (HQC concentration).
