In order to identify Xinhui Citri Reticulatae Pericarpium rapidly and non-destructively, headspace solid-phase microextraction two-dimensional gas chromatog. time-of-flight mass spectrometry (HS/SPME-GC脳GC-TOFMS) combined with chemometrics was used to analyze the volatile components of Xinhui Citri Reticulatae Pericarpium and Citri Reticulatae Pericarpium from other habitats. The volatile components of Citri Reticulatae Pericarpium were enriched and concentrated by headspace solid-phase microextraction (HS-SPME). The volatile components were analyzed by two-dimensional gas chromatog. time-of-flight mass spectrometry. The fingerprint chromatograms were used for distinguishing Xinhui Citri Reticulatae Pericarpium from different sources. Canvas software was used to obtain the qual. information of the volatile components and the relative peak areas of the samples. Principal component anal. (PCA) and orthogonal partial least squares discrimination anal. (OPLS-DA) were used to differentiate the compounds between Xinhui Citri Reticulatae Pericarpium and others. The results showed that about 500 compounds were detected in a single sample, and 102 common components in Xinhui Citri Reticulatae Pericarpium were obtained through screening, which was used to characterize the volatile components Xinhui Citri Reticulatae Pericarpium. The common components were mainly terpenes and alcs. and it together formed the unique aroma characteristics and pharmacol. effects of Xinhui Citri Reticulatae Pericarpium. Principal component anal. (PCA) and orthogonal partial least squares (OPLS-DA) were used to identify Xinhui Citri Reticulatae Pericarpium and other Citri Reticulatae Pericarpium, and 13 potential differential compounds between Xinhui Citri Reticulatae Pericarpium and other Citri Reticulatae Pericarpium were obtained. Moreover, methylene ketone was only detected in Xinhui Pericarpium Citri Reticulatae. Overall, our results showed that HS/SPME-GC脳GC-TOFMS combined with chemometrics is promising method for identifying Xinhui Citri Reticulatae Pericarpium, and proposed a new strategy to evaluate the quality of other traditional Chinese medicines. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Electric Literature of C10H20O2).
Octyl acetate (cas: 112-14-1) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Electric Literature of C10H20O2
