Test No.	Volume Ratios of Moble Phase (Acetonitrile–Water) (n = 3)	Peak Purity of Ginsenoside F₅ (%) ^a,b	RSD (%) (Ginsenoside F₅)	Peak Purity of Ginsenoside F₃ (%) ^a,b	RSD (%) (Ginsenoside F₃)
1	28:72	96.55 ± 1.18	1.22	94.69 ± 1.25	1.32
2	32:68	96.19 ± 1.35	1.41	90.47 ± 2.45	2.71
3	32:68 → 28:72 (15 min)	95.87 ± 0.87	0.91	94.09 ± 1.02	1.08
4	32:68 → 28:72 (10 min)	96.96 ± 1.04	1.08	97.18 ± 1.27	1.30

^a Peak purity: calculated by the peak area normalization method; ^b Results of peak purity are the means ± SD of four independent experiments performed in triplicate.
