The present work was carried out to investigate and separate the chemical components present in the Rosa rubiginosa and to perform a synthesis of 2׳-Hydroxy Chalcone a natural product. Roses are widely distributed in various parts of the world. The chief component present in any of the species of Rose is essential rose oil. This rose oil consists of hundreds of components in it and separation of these components is quite difficult. The work was divided into two parts. In the first part, extraction of fresh petals of Rosa rubiginosa was carried out by solvent extraction method using hexane as a solvent and four components were isolated. In the second part, a synthesis of 2׳-Hydroxy Chalcone was done. Literature study includes two methods for the synthesis of Chalcone. One is Claisen-Schmidt condensation and other is Aldol condensation. The method adopted to carry out the synthesis of 2׳-Hydroxy Chalcone was Aldol condensation in the presence of sodium hydroxide because it yielded a good quantity of product. Different Chromatographic techniques like column chromatography and thin layer chromatography, as well as spectroscopic techniques like IR, UV, and NMR, were used for identification of the products.
