Antioxidant activity (reducing power, β-carotene bleaching assay, and ferrous-chelating activity) and antioxidant capacity (TPC and TFC) of J. sambac flower extracts at various mixture ratios.

	1 : 9	2 : 8	3 : 7	4 : 6
Reducing power, IC50 (mg/L)	258 ± 18.6	273 ± 24.2	306 ± 30.1	324 ± 12.8
β-Carotene bleaching assay, IC50 (mg/L)	602 ± 36.4	547 ± 20.8	512 ± 16.5	456 ± 34.1
Fe(II) chelating activity, IC50 (mg/L)	394 ± 32.1	421 ± 38.5	466 ± 32.8	512 ± 46.2
TPC (mg-gae/g)	180.43 ± 10.36	172.15 ± 8.75	163.89 ± 12.74	138.95 ± 7.87
TFC (mg-cae/g)	10.02 ± 0.92	9.17 ± 1.24	8.35 ± 0.63	7.54 ± 0.83

The PCP was produced by mixing 2,000 mg/L 100%SFE and 4,000 mg/L RO at various mixture ratios.
