Objective: To determine the contents of loganic acid and gentiopicroside during seed germination in Gentiana crassicaulis. Method: HPLC method for simultaneous determination of loganic acid and gentiopicroside during seed germination in G. crassicaulis. The separation was done on Cat C18 (4.6 mm×150 mm
3.5 μm) column with eluted with acetonitrile (A)-0.04% acetic acid solution (B) as the mobile phase for gradient elution. The flow rate was 0.8 mL·min-1. The detect wave length was set at 254 nm. The column temperature was kept at 30℃
and the sample volume was 5 μL to determine the contents of loganic acid and gentiopicroside during seed germination. Result: Loganic acid and gentiopicroside were well separated with ideal linear correlations within the range of 35.5~761.5 mg·L-1 (r1=1.000 0) and 4.8~103.1 mg·L-1 (r2=0.999 9) respectively. The average recoveries were 98.30% (RSD 1.9%) and 99.85% (RSD 2.6%) respectively. During germination
the content of loganic acid rose and the content of gentiopicroside declined gradually. Conclusion: A negative correlation of loganic acid and gentiopicroside is present during seed germination of G. crassicaulis
and the correlation degree is related to seed germination percentage.
