BMC Research Notes

Table 4 Polyphenolics content in methanolic extract of R. purpurea tuber

S. no.	Total poly phenolics^b	Values^a	Regression equation (y)	Regression coefficient (r²)
1.	Total phenolics	14.13 ± 0.115	115.9 x + 0.113	0.999
2.	Total flavonoids	12.23 ± 0.055	74.61x + 0.058	0.998

^aValues are mean ± SD (n = 3).
^bTotal phenolics are represented as mg Gallic acid/gm of dry weight, total flavonoids are represented as mg quercetin/gm of dry weight.
