| titleOfInvention | A kind of qualitative method of tea seeds phenolic compound |
| abstract | The invention discloses a kind of qualitative methods of tea seeds phenolic compound, it is characterized in that being identified using ultra performance liquid chromatography-level four bars-flight time tandem mass spectrometry, tea seeds powder detects to obtain total ion chromatogram and extracts characteristic ion chromatogram after carrying out pre-treatment by ultra performance liquid chromatography-level four bars-flight time tandem mass spectrum, calculate the corresponding compound of ion by the qualitative software of Q-TOF and accurate molecular weight, Preliminary Identification is carried out to unknown compound according to element composition and accurate molecular weight, the cracking of collision-induced unknown compound, phenolic compound type in tea seeds is inferred according to the cracking situation of ion.This method has the advantages that compared with existing phenolic compound qualitative method without standard items, sensitivity for analysis is high, selectivity is good. |
