A new 1β-hydroxy-ent-kauren diterpenoid, enanderianin C1, has been isolated from the leaves of Isodon enanderianus, and its structure has been elucidated by spectroscopic evidences.
One new scsquiterpene polyol esters was isolated from the leaf ofCelastrus angulatus. Its structure was elucidated on the basis of UV, IR, mass, 1H-NMR, (13)C-NMR and 1H-(13)C long-range correlation spectroscopy as 1...One new scsquiterpene polyol esters was isolated from the leaf ofCelastrus angulatus. Its structure was elucidated on the basis of UV, IR, mass, 1H-NMR, (13)C-NMR and 1H-(13)C long-range correlation spectroscopy as 1β-cinnamoyloxy-2β, 6α, 8α, 9α,12-pentaacetoxy-β-dihydroagarofuran.展开更多
