Musa spp. peel is rich in phytochemicals such as carotenoids and phenolic compounds, which might be related to its antioxidant potential. Chemical analysis is an interesting add-value approach to that residual biomass. High performance liquid chromatography (HPLC) and UV-visible spectrophotometry techniques have been used to analyze the chemical composition of complex matrices such crude extracts of plant materials, i.e., banana peel. Thus, this study aimed to identify and quantify carotenoids and phenolic compounds extracted from organic banana peel (Musa spp. cv. Prata An??) samples over the harvest times July/2010 to December/2011 by UV-Vis spectrophotometry and RP-HPLC_UV-vis.  ectrophotometric analyses showed an average content of 1.45 ?? 0.42μg.g- 1 for total carotenoids with a major value of 2.35 ?? 0.06μg.g-1 (September/2010) and a lower one of 0.96 ?? 0.01μg.g-1 - December/2011). In its turn, a quite higher amount of total phenolic compounds was detected, i.e., average = 36.12 ?? 7.54 mg.g-1 The chromatographic profiles of the samples revealed the presence of lutein, zeaxanthin, ??-cryptoxanthin, ??- and a-carotene in decreasing amounts, as well as cathechins. UV-VIS spectrophotometry and HPLC can be considered important techniques to identify and quantify carotenoids and phenolic compounds extracted from banana peel.  aBiochemistry  aMusa  tIn: WORLD CONGRESS OF FOOD AND SECURITY, 16., 2012, Foz do Igua????, PR.
