Evaluation of Method Performance and Biological Variations for Oxidative Stress Biomarkers in Plant Extracts: A Method Validation Study

Abstract

In this study, it was aimed to determine biological variations and analytical quality specifications to evaluate the acceptability of method performance for oxidative stress biomarkers in Silybum marianum (Milk thistle) and Artemisia absinthium (Wormwood) plant extracts. Silybum marianum and Artemisia absinthium were used in the study. Samples were taken from plants on the zero, 1st, 3rd, 5th, 7th, 15th and 30th days. Index of individuality (II) and reference change value (RCV) were calculated from within-subject (CVI) and between-subject (CVG) variations. Moreover, imprecision, bias and total error were calculated as analytical quality specifications. Oxidative stress biomarkers [catalase (CAT), superoxide dismutase (SOD) and malondialdehyde (MDA)] in plant extracts were measured as spectrophotometric methods. Compared to Artemisia absinthium, higher antioxidant enzyme activities (SOD and CAT) and lower MDA levels in Silybum marianum were found in our study (p<0.05). MDA in plants showed low individuality, and CVI of MDA were larger than CVG. However, CAT and SOD in plants showed strong individuality, but CVI of them were smaller than CVG. CAT and SOD except, RCVs of MDA analyte were relatively higher, because of high CVI, resulting in a higher RCV. Also, the described methodology achieves these goals, with analytical CVs of < 3.5% for all analytes. Goals for bias and total error were 11.2-25.2% and 8.93-27.6%, respectively. The RCV concept for predicting that the plant is diseased by some causative agent resulting in an abnormal physiological process can be a valuable tool in demonstrating laboratory optimization. Moreover, desirable precision targets based on biological variation for measurements of oxidative stress biomarkers in plants can be achieved with current methodologies.
