Chemical constituents with prenyl substitution from the stem and root of Daphne giraldii Nitsche. (Thymelaeaceae)

Publication date: December 2019Source: Biochemical Systematics and Ecology, Volume 87Author(s): Ying Liu, Qian Sun, Lingzhi Li, Shaojiang SongAbstractPhytochemical characterization of the stem and root bark of Daphne giraldii Nitsche. led to the isolation of eight flavones (1–8), six flavans (9–14) and six coumarins (15–20). The structures of these compounds were examined with spectroscopic methods, and also by comparing to previously reported spectroscopic data. Among them, ten compounds (1–3, 9 and 15–20) are reported for the first time for this species, and all compounds with prenyl substitutions have not been identified in other species of genus Daphne, or even in the family Thymelaeaceae. We also describe the chemotaxonomic significance of these compounds.
