- The experimental values are means of three independent determinations. a,b,c Mean values within a row with different superscript letters differ significantly and were determined as mentioned in Methods (ANOVA, Tukey, p < 0.05). Separate analysis was done for each row.
- ND not detected; NS not specified.
- * Experimentally determined values followed by predicted ones, if any, in brackets.
- # Predicted values as mentioned in Methods.
- ** Calculated using experimental SN and IV while the values in brackets determined from predicted ones.
