Chromatography and spectroscopy techniques are the most commonly used methods in standardization of herbal medicines but the herbal system is not easy to analyze because of their complexity of chemical composition. Many cutting-edge analytical technologies have been introduced to evaluate the quality of medicinal plants and significant amount of measurement data has been produced. Chemometric techniques provide a good opportunity for mining more useful chemical information from the original data. Then, the application of chemometrics in the field of medicinal plants is spontaneous and necessary. Comprehensive methods and hyphenated techniques associated with chemometrics used for extracting useful information and supplying various methods of data processing are now more and more widely used in medicinal plants, among which chemometrics resolution methods and principal component analysis (PCA) are most commonly used techniques. This review focuses on the recent various important analytical techniques, important chemometrics tools and interpretation of results by PCA, and applications of chemometrics in quality evaluation of medicinal plants in the authenticity, efficacy and consistency.

“…First, the background can be estimated by eigenvalue decomposition of the data of the zero component region before and after the chromatographic peak, and then it can be deducted through least squares [ 13 , 17 ]. Then the rankmap was obtained with a fixed size moving wndow evolving factor analysis (FSMWEFA) [ 18 ], and was shown in Figure 3 .…”

“…Therefore, developing a simple and reliable approach for the determination of the volatile constituents in Radix Flemingiae Philippinensis is necessary. To date many associated methods have been developed to provide more information for chemical analysis both in chromatographic separation and in spectral identification, such as evolving factor analysis (EFA) [ 6 , 7 ], window factor analysis (WFA) [ 8 ], heuristic evolving latent projections (HELP) [ 9 , 10 ], subwindow factor analysis (SFA) [ 11 , 12 ].These methods make resolution of complex systems possible [ 13 , 14 , 15 ]. In this paper, the volatile compounds in Radix Flemingiae Philippinensis were studied with GC–MS and heuristic evolving latent projections (HELP).…”

With the help of chemometric resolution methods, a technique for qualitative and quantitative determination of the volatile chemical constituents in Radix Flemingiae Philippinensis by chromatography-mass spectrometry was developed. After the overlapping chromatographic peaks were resolved into pure chromatograms and spectra using a heuristic evolving latent projections (HELP) method, qualitative analysis was performed by similarity search of the obtained pure mass spectrum of each component in the NIST library and the quantitative results were obtained by calculating the total two-way response volume. A total of 63 components were separated and 55 components were identified, accounting for 90.62% of the total content. The main components were farnesol isomer and β-caryophyllene, accounting for 31.33% and 12.60% of the total content, respectively. The obtained results can provide useful information for further study and development of Radix Flemingiae Philippinensis.

“…A new chemometric method, known as alternative moving window factor analysis (AMWFA), has been introduced to solve this problem (Zeng et al, 2007a;Wang et al, 2008). Several studies have applied methods such as these for resolving overlapping peaks (Guo et al, 2003(Guo et al, , 2004aGong et al, 2004;Zhao et al, 2006;Yi et al, 2007Yi et al, , 2009Zeng et al, 2007a).…”

“…For example, OPA and EWOP were utilised for solving complex chromatographic systems of Notopter giumincium (Guo et al, 2003). A similar study was carried out for Artemisia capillaries with the aid of EWOP and FSMWEFA (Guo et al, 2004a). Several studies were conducted for quality control of the herb Houttuynia cordat utilising different resolution methods (Xu et al, 2005Zeng et al, 2007b).…”
