Reducing potential of methanolic extract of stem of Plectranthus amboinicus.

Concentration (ppm)	Methanolic extract	Ascorbic acid*
25	0.085 ± 0.003^a	0.894 ± 0.001^a
50	0.161 ± 0.008^b	1.77 ± 0.17^b
75	0.227 ± 0.004^c	ND
100	0.293 ± 0.006^d	ND
125	0.347 ± 0.021^e	ND

∗Ascorbic acid was used as a positive control.
ND: not detectable; values are not readable in spectrophotometer (>3.7 OD).
Values followed by different letters in a column are significantly different (𝑃≤0.05) from each other.
