Table 1.

The total phenolic contents, flavonoids contents, and antioxidant activity of RP jelly drink and placebo jelly drink.

Parameters	RP jelly drink	Placebo jelly drink	P value
Total phenolic content, mg GAE/g DW	1.97 ± 0.03	0.98 ± 0.01	<0.001
Flavonoid content, mg QE/g DW	1.79 ± 0.20	0.87 ± 0.12	0.002
DPPH (IC50), mg/mL	2.87 ± 0.05	4.79 ± 0.02	<0.001

Data are expressed as mean ± standard deviations. Data were analyzed using independent t-test for comparing the parameters between study groups. GAE: gallic acid equivalent; DW: dried weight; QE: quercetin equivalent; DPPH: 2, 2-diphenyl-1-picrylhydrazyl.
