Optimization of the extraction conditions of polyphenolic compounds for different parts of the Damas species, Conocarpus lancifolius and Conocarpus erectus, grown under UAE conditions was studied. The combination of ethanol concentration (50, 75, and 100%), temperature (45, 55, and 65 °C) and time (1, 2, and 3 h) was used by applying the Response Surface Methodology. The data showed that the extracts (n = 90) contained phenolic compounds, flavonoids, and tannins, and were free of alkaloids. Changing the extraction conditions had a significant effect on the detection of phytosterols, saponins, and glycosides and on the solubility of vanillic acid, p-coumaric acid, sinapic acid, t-ferulic acid, rutin hydrate, protocatechuic acid, quercetin, and flavone. The data reveal that the roots and leaves of C. erectus and the leaves and fruits of C.lancifolius are the most important plant parts from which to extract these compounds. This study draws attention to the unordinary use of Conocarpus spp. as a source of natural food additive.
