| Abstract: | The liquid chromatographic method was described for the determination of validamycin A in rice and rice husks.The residues of validamycin A were extracted with solvent,followed by purification with SPE-C18,and utilizing HPLC to quantify the extract.The results showed that the recoveries of the method were 80.08%-87.66% with RSD being 8.26%-13.58%,the linear range of working curve were 0.8-80 mg·L-1,and the linear correlation was 0.999 9. |
| Keywords: | validamycin A liquid chromatography SPE-C18 residual analysis |
