Herbal medicines along with its preparations have been commonly used in preventive and promotive agents around the world, especially in developing countries. Motivated by economical profits, the high priced value of herbal medicines may be substituted or adulterated with less expensive ones, therefore the authentication methods must be developed to overcome the adulteration practices. Due to its properties as fingerprint analytical techniques, near-infrared (NIR) and mid infrared (MIR) spectroscopy offered fast and reliable techniques for authentication of herbal medicine. The data generated during authentication of herbal medicines were complex and difficult to be interpreted, as a consequence, the statistical approach called with chemometrics has been used to treat data. The objective of present review was to highlight the updates on application of NIR and MIR spectroscopy and chemometrics techniques (discrimination, classification, and quantification) for discrimination and authentication of herbal medicine.
Key words: herbal medicine, authentication, NIR spectroscopy, MIR spectroscopy, chemometrics.
