Abstract
Objective: To establish a determination method for different varieties of rutinand quercetin in Gynostemma pentaphyllum from different producing areas. Method: HPLC was performed on ZORBAX SB-C18column (4.6 mm×150 mm
5 μm)
eluting in a gradient mode with the mobile phase of acetonitrile (A ) -0.2%H3PO4 as (B) at a flow rate of 1.0 mL·min-1. The column temperature was 30 ℃. The detection wavelength was 360 nm. The injection volume was 10 μL. Result: The linearity of rutin was good within the range of 2.535-10.14 μg (R2=0.999 2)
and the average recovery was 98.72%(RSD 1.2%). The linearity of quercetin was good within the range of 0.018 1-0.144 8 μg (R2=0.999 3)
and the average recovery of 98.40%(RSD 1.7%). Conclusion: The established method is simple
feasible and highly reproducible
and can be used for determining rutin and quercetin in G. pentaphyllum and providing reference for quality control of G. pentaphyllum.
