Qualitative characterization of phenolic profile of the fruits and leaves of Solanum torvum Swart naturally growing in Côte d'Ivoire

The polyphenol phytochemical constituents have a positive impact on health and in the prevention of various diseases. The current study aimed at qualititative phytochemical analysis of Solanum torvum from Côte d'Ivoire, in order to knowledge phenolic potential of plant for futurs reseachs. The leaves and fruits of Solanum torvum were collected in Daloa province of Côte d'Ivoire, dried, ground to powder and extracted using differents solvents. The dry extract purified was dissolved in methanol and filtered through a Millipore membrane with 0.22μm porosity. Then, each of extracts was further subjected to TLC and HPLC. Total phenolic and flavonoid contents were evaluated using Folin-Ciocalteu method and aluminium trichloride test, respectively. The results revealed that leaves extracts accumulated significantly higher phenolic content 86.071.49mg GAE/g DW and flavonoid content 2.510.14mg GAE/g DW than extracts fruits. The chromatography analyse showed eigteen compounds in fruits fraction and twenty compounds in leaves fraction. Chromatography identification conducted on ethyl acetate fraction revealed the presence of phenolics acid, flavonoids and coumaric acid. Most of identified compounds are already were isolated by previous phytochemical investigations on Solanum except arbutin, tannic acid and p-coumaric acid. These major active compounds have various biological activities and play a known role in maintaining good health. The results show Solanum from Côte d'Ivoire have the same abilities as other species in the world. The knowledge of phenolic profile of Solanum torvum from Côte d'Ivoire are very important for their authentication, conservation and utilization of biological resources.
