“…HCA builds a hierarchy of clusters of data of varying similarity, typically represented by a dendrogram. Application of PCA and HCA to chromatographic data treatment has become popular in the last two decades (Coltro et al, 2005), and these approaches are currently widely applied in plant compound analyses (Chun et al, 2011;Zhang et al, 2013;Gong et al, 2014;Benevides et al, 2014). Thus, in addition to univariate analyses, we used multivariate analyses to gain insight into the similarity and dissimilarity of emission profiles among the treatments.…”

“…[20,21] In previous studies, gas chromatography-mass spectrometry (GC-MS) combined with chemometrics methods had been used to distinguish SS from different regions. [22,23] However, few studies have done to analyze the correlation between the color and chemical composition in SS. Therefore, the investigation into the chemical difference of SS in different colors could be developed as an important approach to evaluate the quality of SS.…”

Schizonepetae Spica (SS), the dried spike of Schizonepeta tenuifolia Briq., is a traditional Chinese medicinal herb. According to the color of persistent calyx, SS is categorized into two classes: the yellowish-green-type and the brownish-type. Based on the chemometrics analysis of gas chromatography-mass spectrometry (GC-MS), a novel model of identifying and evaluating the quality of SS in different colors was constructed for the first time in this work. 20 batches SS samples of different colors were collected and used to extract essential oils. The average essential oils yield of SS in yellowish-green color was significantly higher than that of SS in brownish color from the same origin (p<0.05). The GC-MS fingerprints of 20 batches SS samples whose correlation coefficients were over 0.964 demonstrated SS samples were consistent to some extent in spite of slightly different chemical indexes. A total of 39 common volatiles compounds were identified. Hierarchical clustering analysis (HCA), principal component analysis (PCA) and partial least-squares discriminate analysis (PLS-DA) were developed to distinguish SS samples characterized by different colors. Consistent results were obtained to show that SS samples could be successfully grouped according to their color. Finally, 4,5,6,7-tetrahydro-3,6-dimethyl-benzofuran and pulegone were detected as the key variables for discriminating SS samples of different colors and for quality control. The obtained results proved that SS of good quality were often yellowishgreen and those of poor quality were often brownish.

“…Fingerprints have been developed by GC-MS for the quality control of Portula caoleracea from different sources, coupled with SA and HCA samples were divided into two main clusters: one was from North China and another from South China . Discrimination of Schizonepeta tenuifolia from different origins has been achieved by PCA and HCA, which classified the samples into two main groups on the basis of five marker compounds (Chun et al, 2011). Chromatographic fingerprinting by GC-MS coupled with SA and PCA has been undertaken for analysis of Scutellaria barbata from different producing areas of China and for discrimination of their adulterants.…”
