The phytochem. investigation of the chloroform soluble fraction of Caryopteris odorata (Ham. ex Roxb.) led to the isolation of one new constituent namely; n-pentadecyl[3-(4-hydroxyphenyl)] propanoate (I). The compounds 2-ethyl-n-hexyl benzoate (2), 2-ethyl-n-hexyl trans-cinnamate (3) bis-dodecylbenzene-1,4-dicarboxylate (4) were reported synthetically but these have been isolated for the first time from a natural source. Similarly, the known constituent like trans-cinnamic acid (5) and cis-cinnamic acid (6), heneicosanoic acid (7), Me tricontanoate (8) and octacosanyl tricontanoate (9) were also obtained for the first time from this plant source. The structures of these compounds were determined by IR, HR-MS, 1H-NMR, 13C-NMR spectroscopy and by comparison with the published data of the closely related compounds These isolates were screened for their antioxidant, anti-urease and anti-tyrosinase activities and results revealed that n-Pentadecyl [3-(4-hydroxyphenyl)] propanoate (1) exhibits good antioxidant potential with low to zero enzyme inhibition activities. This study involved multiple reactions and reactants, such as 2-Ethylhexyl benzoate (cas: 5444-75-7Category: esters-buliding-blocks).
2-Ethylhexyl benzoate (cas: 5444-75-7) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Category: esters-buliding-blocks
