Comparison of percentage recovery yield, extraction time and volume of solvent used for the different extraction methods for the two plants

	*Vernonia amygdalina*			*Ocimum gratissimum*
Parameter	MAE	Soxhlet	Maceration	MAE	Soxhlet	Maceration
Sample (g)	50	50	50	50	50	50
Solvent volume (mL)	250	500	900	250	500	900
Extraction time (min)	39	265	4320	39	255	4320
Recovery yield (g)	10.45 ± 0.53^b	7.88 ± 0.35^a	7.18 ± 0.14^a	9.55 ± 0.84^b	5.63 ± 0.21^a	5.08 ± 0.32^a
Percentage recovered (%)	20.90 ± 1.05^b	15.75 ± 0.71^a	14.35 ± 0.28^a	19.10 ± 1.67^b	11.25 ± 0.24^a	10.15 ± 0.65^a

Values are mean ± SD of 3 replicate determinations; same superscript across the column under the same plant indicate no significant difference (P > 0.05). MAE: Microwave-assisted-extraction.
