| titleOfInvention | A kind of method that use SPE HPLC determine phenoloid in the dried immature fruit of citron orange or Fructus Aurantii |
| abstract | The present invention relates to a kind of method that use SPE HPLC determine phenoloid in the dried immature fruit of citron orange or Fructus Aurantii.Its specific steps includes：The dried immature fruit of citron orange or Fructus Aurantii powder are taken, it is accurate weighed, put in conical flask with cover, precision adds methanol, and ultrasonic extraction is let cool, shake up, filter, precision measure filtrate decompression be recycled to it is dry, dissolved with water, flow through the solid phase extraction column crossed in advance with methanol and water balance, then eluted successively with methanol, eluted with pure methanol, pure methanol-eluted fractions constant volume is collected, miillpore filter filtration produces test fluid；The measure of phenoloid.Compared with prior art, the present invention has carried out pre-treatment using SPE to sample, reduces influence of the impurity component to measure, and SPE has the advantages that easy to operate, accumulation rate is high, consumption solvent is few, cost is low, collection extraction is integral with being located away from.In addition, the chromatographic condition that this law is set up has preferable separating degree to each phenoloid to be checked, and analysis condition is suitable. |
