A study of the real possibilities of carbohydrate profiles and chemometrics to characterize the botanicalorigin of honey from a single geographical area, the Province of Soria (Spain), is presented. To thisend, 14 carbohydrates were quantified using high-performance liquid chromatography (HPLC) withpulsed amperometric detection (PAD) in 77 natural honeys, the botanical origins of which were ling,spike lavender, French lavender, thyme, forest, and multifloral. Principal component analysis hasbeen employed as a first approach to characterize the honey samples analyzed, showing similaritiesbetween spike lavender and multifloral honeys. The best discrimination among groups is obtainedwhen four canonical discriminant analyses were carried out sequentially, origin by origin, achievingan overall percentage of success of 90% following cross-validation.Keywords: Carbohydrate profiles; chemometrics; blossom honey; characterization; pulsed amperometric detection; HPLC
