Results are expressed as the mean of three replicates ± the standard error of the mean.

n/d = not detected.

a Yield was calculated as (mass recovered extract / mass dry material) × 100%.

b Expressed as mg quercetin equivalents / g extract as determined using with the Folin Ciocalteau method.

✓ Presence detected but not quantified.
