Methods The compounds were isolated by silica gel column chromatography and identified by spectral analysis. Results Sixteen compounds were identified as evodiamine （1）, rutaecarpine （2）, β-sitosterol （3）, isorhamnetin（4）, evodol （5）, quercetin （6）, limonin （7）, wuzhuyurutine A （8）, evodirutaenin （9）, shihulimonin A （10）, wuzhuyurutine B（ll）, wuchuyuamide Ⅰ （12）, daucosterol （13）, trans-caffeic acid methylate （14）, dehydroevodiamine （15）and sucrose （16）. Conclusion Compounds 4, 6, 10 and 14 were isolated from the title plant for the first time.展开更多

The RP-HPLC assay was performed on a reversed-phase Cl8 column with a gradient elution. The mobile phases consisted of methanol and water containing 1% （v/v） acetic acid. The flow rate was 1.0 mL/min and the detection wavelength was set at 300 nm. All calibration curves showed good linearity （r2〉0.9941） within test ranges. The results of intra-day precision, inter-day precision, and accuracy were satisfactory. The overall recoveries were in the range of 90.13%-102.48%. The method was successfully applied to quantify nine bioactive compounds in six samples. Baseline resolution for all nine major compounds was achieved. This method could be used as a suitable quality control assay for Wuzhuyu decoction.展开更多
