摘要
This peper discussed the determination method of flavonoid compounds in Gingko biloba leaved with supercritical CO2 and HPLC,The method is aimple and accurate. It can eliminate the toxicity of residual solvents in organic solvent extracts. The average recovery is 87.3% (n=4), relative standard deviation (RSD)ie 5.4% and the method detection limit (MDL) is 28ppb. The flavonoid contentdetermined wae 1.4%(w/w) in Gingko biloba leaves.
