Twelve new diterpenes, caryopincaolide A-L (1-4, 11-12, 16-19, 27-28), together with twenty-eight known diterpenes, have been isolated from the whole plant of Caryopteris incana (Thunb.) Miq. Their structures were elucidated on the basis of 1D and 2D NMR, IR, X-ray crystal diffraction and mass
Nepetaefolins A-J (1-10) and seven known compounds were isolated from the whole plant of Caryopteris nepetaefolia. The absolute configurations of 1-3 were determined from single-crystal X-ray diffraction and spectroscopic data. Compounds 6 and 7, with IC50 values of 6.3-9.0 μM, showed higher
Aim. In the present study, we investigated the antiangiogenic properties of 59 plants used in traditional Korean medicine. Selected phytochemicals were investigated in more detail for their modes of action. Methods. A modified chicken-chorioallantoic-membrane (CAM) assay using quail eggs was applied
