Honey is considered a complex matrix for presenting a range of secondary metabolites originating from the regional flora. It has been highlighted as a functional food consumed worldwide and frequently suffering from adulteration. Fraud methods have been sophisticated over the years, indicating the need of a continuous updating of the existing analysis methods. For this reason, analytical techniques applied to honey have been expanded, allowing the detection of fraud and the determination of geographic and botanical origin, to guarantee the authenticity of the product. In this sense, this study aimed to characterize floral honey samples in 2019-2020 and 2020-2021 harvests in the states of Santa Catarina (SC, southern Brazil - n = 73) and São Paulo (SP, southeastern Brazil - n = 59), through UV-vis, NIR, and NMR spectroscopies. The total reduced capacity showed a wide variation (0.76-12.8 mg GAE.g
