TPC results* by different solvents and extraction types Microwave Assisted Extraction (MAE) versus Ultrasound Assisted Extraction (UAE).

Lyophilised Samples/Extraction Type	Kernels		Hulls		Press Residue
Lyophilised Samples/Extraction Type	Aq.MeOH	MeOH	Aq.MeOH	MeOH	Aq.MeOH	MeOH
MAE	160.0 ± 30.0 ^b,c	80.7 ± 4.5 ^a,c	80.0 ± 15.0 ^b,c	35.5 ± 2.5 ^a,c	107.4 ± 3.2 ^a,b	46.4 ± 3.8 ^a,b
UAE	325.5 ± 23.2 ^c	163.0 ± 19.2 ^c,†	165.5 ± 9.1 ^c	72.0 ± 11.2 ^c,†	215.0 ± 94.3 ^a,b,†	93.0 ± 4.2 ^a,b,†

* Results are in (μg GAE/mg dry extract, mean ± SE). Significant differences (p < 0.05) are shown by ^a,b,c letters in the same column; (^†) shows statistically significant values for the two extraction methods (p < 0.05). MAE stands for Microwave Assisted Extraction and UAE stands for Ultrasound Assisted Extraction.
