Phytochemical prospection of the floral extract of Ouratea spectabilis (Mart.) Engl. (Ochnaceae)

Abstract

Ouratea spectabilis is a tree species belonging to the genus Ouratea and the family Ochnaceae. This study aimed to report the first report on the phytochemical constitution of the floral extract of O. spectabilis. Flowers were collected from individuals of O. spectabilis in a Cerrado area in Rio Verde, Goiás, Brasil in 2022. The extract was produced from 150g of floral organ. The extract yield was determined by the difference in mass, visual analysis, crystallinity and homogeneity were performed by the organoleptic method, pH and electrical conductivity were determined using a pHmeter and conductivitymeter both digital. The qualitative phytochemical profile was performed for several groups of phytomolecules of the special metabolism of this plant using specific reagents. The floral extract yield was 11.81%, several phytochemical groups were observed, such as phenolics, saponins, flavonoids, steroids, triterpenoids, organic acids, reducing sugars, aromatic compounds, alkaloids and amino acids. The floral extract of Ouratea spectabilis showed high potential for future work on chemical quantification and assays with different biological models.
