Objective: To establish an HPLC method for determination of changes of characteristic components before and after the compatibility of Gentianae Macrophyllae Radix-Clematidis Radix et Rhizoma
Gentianae Macrophyllae Radix-Taxilli Herba
and Gentianae Macrophyllae Radix-Stephaniae Teerandrae Radix. Method: The chromatographic column was Agilent A3000250×046 Pursuit 5 C18 (4.6 mm×250 mm
5 μm)
with 0.04% phosphoricacid solution (A)-acetonitrile (B) as the mobile phase for gradient elution (0-15 min
5% -15% B;15-25 min
15% -25% B;25-35 min
25% -35% B;35-40 min
35% -70% B;40-55 min
70% -95% B) at the flow rate of 0.8 mL·min-1. The detection wavelength was set at 220 nm
and the column temperature was set at 25 ℃. Result: The 16 characteristic peaks (w1-w16) were isolated from Gentianae Macrophyllae Radix-Clematidis Radix et Rhizoma herbal pair;18 characteristic peaks (s1-s18) were isolated from Gentianae Macrophyllae Radix-Taxilli Herba herbal pair;and 21 characteristic peaks (f1-f21) were isolated from Gentianae Macrophyllae Radix-Stephaniae Teerandrae Radix herbal pair. Among them
the peak areas of w1

f9 and f20 were not changed. w8
s7 and f9 were swertiamarin;w10
s8 and f11 were gentiamarin;s13
f16 and f17 were quercitin
fangchinoline and tetrandrine. w12
s15
f7 and f18 were the new components produced in the herbal pairs. Conclusion: After Gentianae Macrophyllae Radix compatibility
the contents of characteristic ingredient were changed and new components were generated. The established HPLC method was simple
accurate and repeatable to analyze the changes of characteristic components before and after different Gentianae Macrophyllae Radix drug combinations.
