Chemical constituents from the stem and root bark of Daphne giraldii Nitsche (Thymelaeaceae)

Eighteen compounds were isolated from the stem and root bark of Daphne giraldii Nitsche, including three categories: flavans (1–6), diphenylpropanes (7–12), and lignans (13–18). This is the first report on the occurrence of compounds 9, 11, 13–15, and 17–18 in D. giraldii. These compounds were elucidated using spectroscopic methods and by comparing their data to those reported in the literature. On the basis of our previous chemical research,...
