![]() ![]() The antibacterial effect of these oils and antibiotic potentiating activity, both determined by the minimum inhibitory. EssentialFTIR Download - It is a complete program for handling Fourier Transform Infrared. gardneriana Schauer leaves the seasonal period from January to December 2016 and characterized by attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy. Join for free and gain visibility by uploading your research. Infrared data is represented as two dimensional arrays with Frequency and Absorbance as X and Y vectors. The model performance ranged between 60 and 80% depending on spectroscopic data used for model training and the harvest season. Essential FTIR is a program for the presentation of infrared data. The samples suspected to be either peppermint or spearmint underwent final discrimination using adequate discrimination tools PLS-DA (Partial Least Squares-Discriminant Analysis) or SVM (Support Vector Machines). ![]() Two-step chemometric approach for mints quality control involved SIMCA (Soft Independent Modeling of Class Analogy) to filter out species other than peppermint and spearmint. UV-VIS spectrophotometry and FTIR-ATR spectroscopy were used for recording the spectral fingerprints of a collection of more than 20 mint varieties harvested in three periods. For this reason fast procedure for quality control of at least two most popular mint species, peppermint and spearmint, is the issue at hand. ![]() Chemical compounds differing between species, cause changes in medicinal/pharmacological properties, antioxidant activities or smell sensations. Mints are valued for their specific essential oil used in food, pharmaceutical and cosmetic industry.
