Antiplasmodial ativity of akaloids from Garcinia Parvifolia Miq. Stem Bark
Garciniavalline (1), a novel aporphinoid alkaloid, in addition to four known alkaloids,cleistopholine (2), O-methylmoschatoline (3), (-)-oliveroline (4) and (-)-oliveridine (5), wereisolated and characterized from Garcinia Parvifolia Miq. stem bark. Structural elucidation ofthese compounds was established by spectroscopic methods. Among them, alkaloids (2) and (4)exhibited antiplasmodial activi...
متن کاملFlavonoid and a rare benzophenone glycoside from the leaves of Aquilaria sinensis.
From the leaves of Aquilaria sinensis (LOUR.) GILG, a novel benzophenone glucoside, designated as aquilarinoside A (1), and a new flavonoid, as 7-beta-D-glucoside of 5-O-methylapigenin (2), along with eight known compounds (3-10) were isolated. The structures of 1 and 2 were fully characterized by spectroscopic methods (1D, 2D NMR and MS) and the relative stereochemistry was assigned based on n...

متن کاملAquilarin A, a new benzenoid derivative from the fresh stem of Aquilaria sinensis.
Chemical investigation of the EtOH extract of the fresh stem of Aquilaria sinensis collected in Hainan Province of China resulted in the isolation of a new benzenoid, named aquilarin A (1), together with two known compounds balanophonin (2) and (+)-lariciresinol (3). Their structures were elucidated by a study of their physical and spectral data. Compounds 2 and 3 exhibited cytotoxicity against...
