Differences between the predicted value and the experimental value.

Parameters	Predicted value	Experimental value	Percentage of error (%)
Total flavonoid content (mg RE/g)	64.31 ± 0.00a	67.56 ± 0.83a	4.81
Total phenolic content (mg GAE/g)	152.95 ± 0.00b	155.21 ± 0.67b	1.46
Xanthine oxidase inhibitory activity (%)	88.78 ± 0.00c	91.42 ± 0.74c	2.89

Values were presented as mean ± standard deviation. Same superscripts within the row indicate no significant difference (p > 0.05) between predicted and experimental values.
