HPLC determination of jolkinolide A and jolkinolide B inChinese herb medicine“Lang-du”
To establish a method for the determination of two diterpenoide lactonesjolkinolide A and jolkinolide B in Chinese herbal medicine “Lang-du” by HPLC.Methods:C18column(4.6 mm ×250 mm5 μm)was used with acetonitrile-water(75:25)as the mobile phase.The flow rate was 1.0 mL·min-1and the detection wavelength was 250 nm.Results:By using the established HPLC methodnine samples of “Lang-du” were analyzed to determine the contents of jolkinolide A and B.It was showed that the contents of jolkinolide A and B ranged from 0.007% to 0.043% and 0.012% to 0.204%respectively.Among the samplesthe two diterpenoids were found in most of the samples of Euphorbia fischeriana and E.ebracteolatabut Stellera chamaejasme and Alocasia macrorrhiza contained neither jolkinolide A nor jolkinolide B.Conclusion:A simpleeffective and feasible HPLC method with good accuracyprecision and reproducibility to determine the contents of two diterpenoids in“Lang-du” was established which could be applied for the quality control of this herb.
