Table 4 Comparison of the quantitative phytochemicals obtained with the three extraction methods for the two plants

	Vernonia amygdalina (mg/100 g)			Ocimum gratissimum (mg/100 g)
	MAE	Soxhlet	Maceration	MAE	Soxhlet	Maceration
Alkaloid	4.0 ± 0.65^a	7.0 ± 0.57^b	5.0 ± 0.46^a	6.5 ± 0.75^b	7.0 ± 0.15^b	5.0 ± 0.90^a
Flavonoid	13.0 ± 0.35^b	9.0 ± 0.50^a	15.0 ± 0.21^c	10.0 ± 0.35^b	8.0 ± 0.18^a	12.0 ± 0.25^c
Phenolic	17.5 ± 0.25^c	15.0 ± 0.21^b	12.0 ± 0.70^a	15.0 ± 0.22^c	14.0 ± 0.21^b	11.0 ± 0.65^a
Saponin	4.5 ± 0.45^b	3.0 ± 0.30^a	2.0 ± 0.75^a	6.1 ± 0.75^b	4.0 ± 0.92^a	5.0 ± 0.20^a
Tannin	14.0 ± 0.55^b	13.0 ± 0.50^b	10.0 ± 0.25^a	12.0 ± 0.18^b	9.0 ± 0.24^a	9.1 ± 0.25^a

Values are mean ± SD of 3 replicate readings. Same superscript across the column under the same plant signifies no significant difference at P > 0.05. MAE: Microwave-assisted-extraction.
