dc.description.abstract | We used solvent extractions, SiO2 column chromatographies, and HPLC to isolate from the bark of Thanakha (Hesperethusa crenulata L.) an active crystalline compound for absorbing UV-A radiation (320 to 380 nm). Analyses of low- and high-resolution FAB-MS revealed a compound, named marmesin, with a formula Of C14H14O4 and a molecular mass of 246. To determine its chemical structure, we conducted 300 MMz NMR analyses using various probes, H-1, C-13, and DEPT C-13. Our NMR data showed a structure of 2,3-dihydro-2(1-hydroxy-1-methylethyl)-furanocoumarin. This active compound contains UV-absorbing chromophores, an aromatic ring, a double bond at C3-C4, and a carbonyl at C2. Its lambda(max) is 335 nm, indicating that marmesin could be commercially useful as a natural UV-A-filtering product. | - |
