As herbal medicines have an important position in health care systems worldwide, their current assessment and quality control are a major bottleneck. Recent improvements in advanced analytical instrumentation with improved sensitivity and precision to allow greater resolution of multi-component mixtures are driving the quality-control standards of HMs towards universally acceptable standards. Many cutting-edge analytical technologies have been introduced to evaluate the quality of medicinal plants and significant amount of measurement data has been produced. 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 PCA are most commonly used techniques. This review focuses on the various important recent analytical techniques, important chemometrics tools and interpretation of results by PCA and at last applications of chemometrics in quality evaluation of medicinal plants in the authenticity, efficacy and consistency.
