Bioactive-guided phytochemical investigation of Euphorbia antiquorum L. growing in Vietnam led to the isolation of five ent-atisanes, one seco-ent-atisane, and one lathyrane (ingol-type). The structures were elucidated as ent-1α,3α,16β,17-tetrahyd

The three new lignanoids 1–3 and the five new phyllocladane diterpenoids 7–11 were isolated from the leaves of Callicarpa furfuraceae, together with two known lignanoids, lariciresinol (4) and (+)-sesamin (5), and five known diterpenoids, 17-norp

Earlier phytochemical work on Plectranthus ambiguus (Lamiaceae) afforded a series of tetracyclic phyllocladane-type (=13β-kaurane) diterpenoids (see 1a–f). In the course of investigations concerning the reaction behavior of this rare natural-produ

Six new diterpenoids of the rare phyllocladane (13β-kaurane) type have been isolated from Plectranthus ambiguus. Their structures were determined on the basis of their spectral properties and by correlation with 16R,17-dihydroxyphyllocladane-3-one (
