RESUMO
Objective To develop a method of quantitative analysis of multi-components by single marker (QAMS) for simultaneously determining five compounds in Curcumae Aromaticae Radix.Methods An HPLC method was developed as QAMS to determine curcuma diol,ocathydro-1,4-dihydroxy-1,4-dimethyl-7-(propan-2-ylidene)azulen-5(1H)-one,original curcumol and curcumin in Curcumae Aromaticae Radix,using curdione as intermal reference substance,and the relative correction factor (RCF) of the four components was determined by HPLC with good reproducibility.Their contents in 10 batches of samples,collected from different areas,were determined by both external standard method and QAMS.Result No significant differences were found in the quantitative results of four compounds in 10 batches of Curcumae Aromaticae Radix determined by external standard method and QAMS.Conclusion It is feasible and suitable to evaluate the quality of Curcumae Aromaticae Radix by QAMS.
RESUMO
Objective To develop a method of quantitative analysis of multi-components by single marker (QAMS) for simultaneously determining four compounds in Calonyction muricatum.Method An HPLC method was developed as QAMS to determine ipalbidine,ipalbidinium,and ipalbinium in C.muricatum,using ipalbine as the intermal reference substance,the relative correction factor (RCF) of the three components was determined by HPLC with good reproducibility.Their contents in six batches of samples were determined by both extemal standard method and QAMS.Result No significant differences were found in the quantitative results of three alkaloid compounds in six batches of C.muricatum determined by external standard method and QAMS.Conclusion It is feasible and suitable to evaluate the quality ofcurcuma aromatic by QAMS.
