摘要: An early optimisation of the o-phthaldialdehyde (OPA) method for HPLC-fluorimetric analysis amino acids in honey and bee-pollen made feasible quantification 23, which included five infrequently searched for. Forty samples monovarietal dark honeys, from four botanical origins, were analysed their acids’ profile (which proline) colour. In order to test classification stepwise linear discriminant was applied a number variables selection analytical results simple mathematical functions them. This allowed, firstly, distinguishing honeys these sources with 85.0% cross-validated grouped cases correctly classified. A second application group honeydew honeys—a matter particular interest since no chemical or microscopic exists holm oak oak. Ninety-five percent classified, only one sample misclassified.
