ABSTRACT
Objective To study the chemical constituents from the stem bark of Daphne giraldii. MethodsThe chemical constituents in the alcoholic extract from the stem bark of D. giraldii were isola-ted and purified using liquid/liquid extraction and silica gel column chromatography. The structures of the isolated compounds were determined on the basis of NMR, and mass spectra. ResultsSeven compounds were isolated from the alcohol extract. Their structures were identified as E-octadecyl caffeinate (Ⅰ), (+)-nortrachelogenin (Ⅱ), daphnoretin (Ⅲ), daphneticin (Ⅳ), 7, 8-dihydroxy coumarin (Ⅴ), 7-hydroxy coumarin (Ⅵ), and luteolin (Ⅶ) on the basis of 1H-NMR, 13C-NMR, and MS. ConclusionCompound Ⅰ is a new one. Compounds Ⅱ, Ⅳ, and Ⅶ are isolated from the title plant for the first time.
