Description
Summary:Abstract The juice of blood oranges, especially those of the Citrus sinensis variety Moro, cultivated in the region of Sicily (Italy), is an increasingly popular drink due to its beneficial health properties, such as its ability to reduce abdominal fat, related to its anthocyanin constituents, especially cyanidin-3-O-glycoside (C3G), as demonstrated in pre-clinical and clinical studies. However, the dry extract of C. sinensis juice currently available at compounding pharmacies in Brazil includes samples from various countries, some of which may not have adequate climatic conditions for the production of anthocyanins. In this work, we investigated samples from the three major suppliers (reference, A1, and A2). The composition of the samples was analyzed by LC-UV and LC-MS, total anthocyanin content (TAC), antioxidant activity (DPPH assay), and in vitro anti-inflammatory effect, by NO production in macrophages. C3G was detected only in the reference sample (1.6%), the TAC values were 1.45%, 0.1% and 0.01% in the reference, A1, and A2, respectively. The reference and A1 showed similar antioxidant activity (EC50 of 45.6 and 62.4 µg/mL, respectively), while A2 showed lower activity (EC50 315.1 µg/mL). Only the reference sample showed significant inhibition of NO release, demonstrating the need for quality control of these commercialized samples.
