摘要： The present study aims at building a miniature mass method for the simultaneous determination of 12 phenols including the subtypes of bibenzyl, phenanthrene, and fluorenone, which was used to evaluate the quality of Dendrobium chrysotoxum. Through the full scan mode, new compounds were elucidated. The new compounds were quantified by carrying out the analysis of the ratio of the standard solution areas to new compound areas versus analyte concentration. The limit of detection (LOD) and limit of quantification (LOQ) for phenols were 0.5 mu g/mL-1 mu g/mL and 1 mu g/mL-2 mu g/mL, respectively. Average recoveries of phenols were ranged from 83.2% to 97.5%. Reproducibility represented by the RSD percentage was from 2.3% to 8.7%. The average content of the four analytes, erianin, chrysotobibenzyl, confusarin, and moscatilin, were more than 200 mg/kg, and the content of bibenzyl compounds was found to be the highest in Dendrobium chrysotoxum. Among these bibenzyl compounds, erianin was determined as the typical chemical marker from Dendrobium chrysotoxum. The newly established UPLC with a miniature mass detector method was found to be an appropriate tool for the quality assessment of Dendrobium chrysotoxum.
