Sr. no.	Concentration (μg/mL)	Methanol leaf extract absorbance (nm)	Ascorbic acid absorbance (nm)
1	7.81	0.124 ± 0.00^a	0.131 ± 0.01^a
2	15.62	0.138 ± 0.00^b	0.144 ± 0.01^ab
3	31.25	0.143 ± 0.00^b	0.160 ± 0.00^ab
4	62.5	0.152 ± 0.00^c	0.207 ± 0.03^b
5	125	0.168 ± 0.00^d	0.284 ± 0.00^c
6	250	0.183 ± 0.00^e	0.389 ± 0.03^d

All values are stated as mean ± standard deviation (); values of the same column, followed by the same letter (a to e) are not statistically different () as measured by Tukey’s test.
