Abstract：ObjectiveTo determine the content of alkaloids in wild Pinellia ternate in north east Yunnan area by UV spectrophotometry.MethodsThe bromothymol was used as the chromogenic agent, and the detection wavelength was 407 nm, the calibration curve was linear in the range of 1.6~8.0 μg/ml(r=0.999).ResultsThe content of alkaloids in wild Pinellia ternate was 0.137 7%.ConclusionThe content of alkaloids is very rich in wild pinellia ternate in north east Yunnan area compared to other areas.
