Microwave-Assisted Simultaneous Extraction of Luteolin and Apigenin from Tree Peony Pod and Evaluation of Its Antioxidant Activity

Table 2

Comparison of MAE with other extraction methods, mean ± S.D ().

Number	Extraction method	Extraction time (h)		Solvent consumption (mL/g)	Extraction yield ± SD (μg/g)
		Soak time (h)	Energy consumption time (min)		Luteolin	Apigenin	Total
1	ME	36	0	30	82 ± 4^a	63 ± 3^a	145
2	HRE	0	120	30	131 ± 6^b	89 ± 4^b	220
3	MAE	2	24	30	151 ± 7^c	104 ± 4^c	255

Values followed by the same letter in the same assay are not significantly different ().
