Abstract

The physicochemical properties, proximate composition, minerals, total polyphenols, carotenoids, phenolic compounds, antioxidant, and antibacterial activities of ciricote (Cordia dodecandra A. DC.) tropical fruit were investigated. Minerals were quantified by using micro-Energy Dispersive X-Ray Fluorescence. Lutein and β-carotene were identified in ciricote fruit by using UPLC-PDA analysis. The highest values of the total polyphenols content and antioxidant activity were presented in ethanolic crude extracts obtaining by the ultrasonic-assisted method with freeze-dried fruit. The phenolic acids profile was identified and quantified by UPLC-PDA-ESI-MS. The main phenolic acids were caffeoyl hexoside, rufescenolide, quercetin 3-O-rutinoside, and rosmarinic acid. The ciricote extracts presented antibacterial activity against Staphylococus aureus (Gram+) and Salmonella typhymurium (Gram−). In conclusion, the ciricote (Cordia dodecandra A. DC.) tropical fruits could be very useful source of biological macromolecules, micro-elements, and phytochemical compounds for the food and pharmaceutical industry.

摘要

ciricote ( Cordia dodecandra ) 的理化性质、近似成分、矿物质、总多酚、类胡萝卜素、酚类化合物、抗氧化和抗菌活性A. DC.) 热带水果进行了研究。通过使用微能色散 X 射线荧光对矿物质进行量化。采用 UPLC-PDA 分析法鉴定了柑桔果实中的叶黄素和 β-胡萝卜素。冷冻干燥果实超声辅助法获得的乙醇粗提物中总多酚含量和抗氧化活性最高。通过 UPLC-PDA-ESI-MS 鉴定和量化酚酸谱。主要的酚酸是咖啡酰己糖苷、芸香内酯、槲皮素 3-O-芸香苷和迷迭香酸。ciricote 提取物对金黄色葡萄球菌(Gram+) 和鼠伤寒沙门氏菌(Gram-) 具有抗菌活性。总之，ciricote ( Cordia dodecandraA. DC.) 热带水果可能是食品和制药行业生物大分子、微量元素和植物化学化合物的非常有用的来源。
