Phytochemical, antioxidant and phenolic content Survey of leaves and flowers hydroalcoholic extracts of the Conocarpus erectus and biosynthesis of gold and silver nanoparticles using this extracts

The identification of various bioactive compounds, high phenolic content and high antioxidant activity in extracts of Conocarpus erectus reveals the potential application of this plant as a natural source of antioxidant with the capability of synthesizing nanoparticles for medicine. The aim of this study was to examine the phytochemical compounds in the leaves and flowers of Conocarpus erectus L. and to determine the phenolic content and antioxidant properties of these extracts. Conocarpus erectus L leaves and flowers were extracted utilizing the Soxhlet and Maceration extraction methods. Phytochemical compounds present in plant extracts were analyzed by the use of gas chromatography mass spectrometry. The amount of phenolic content and antioxidant activity in leaf and flower extracts were determined, and the gold and silver nanoparticles were synthesized using these extracts. Additionally the diameter of gold and silver nanoparticles synthesized using extracts of the leaves and flowers were measured. 19 chemical compounds were identified that were mainly in methanolic extracts of leaves prepared by Soxhlet extraction. Steroids were detected in both extracts The amount of phenolic compounds was high. In this study, the extract of flower obtained by Soxhlet method had the highest phenolic compounds. Of the plant extracts evaluated, the extracts obtained by the Soxhlet method had the lowest IC50 and thus the highest antioxidant capacity. Extracts were also utilized in the preparation of nanoparticles of gold and silver.
