Abstract:
To develop a method for determining 3 Xanthone glycosides (1, 5-dihydroxy- 3-methoxyxanthone 8-O-β-D-glucopyranoside(F1), 1-hydroxy-3, 4-dimethoxyxanthon 7-O-β-D-glucopyranoside (F2), 1, 8-dihydroxy-3, 4-dimethoxyxanthone 5-O-β- D-glucopyranoside (F3) of Gentianella acuta by HPLC. The Thermo syncronis C18 (4.6 mmí250 mm, 5 μm) was used for simultaneous determination of 3 Xanthone glycosides in G. acuta. Isocratic elution with water and acetonitrile was 75.5:24.5. The flow rate was 1.0 mL·min-1 and the detection wavelength was set at 254 nm. The column temperature was 35℃. The linear concentration ranges of F1,F2,F3 were 14.06 ~ 281.28 μg·mL-1 (R2=0.999 7),0.56~11.16 μg·mL-1 (R2=0.999 8),0.46~9.20 μg·mL-1 (R2=0.999 9), respectively; The average recov-eries (n = 9) were 99.70% (RSD=1.06%),99.78% (RSD=1.21%),100.28% (RSD=1.15%), respectively. The method is simple, accurate and sensitive, and can be used for the quality control of G. acuta as a reference.
