Subject:
aerial parts; chemical structure; cytotoxicity; glucosides; lignans; nuclear magnetic resonance spectroscopy; protective effect; spectral analysis; Japan
Abstract:
... Six neolignan glucosides, named isodonosides I–VI, and a megastigmane glucoside named isodonmegastigmane I, were isolated together with 15 known compounds from the methanolic extract of aerial parts of Isodon japonicus cultivated in Tokushima, Japan. The chemical structures of the compounds were elucidated based on their MS and NMR spectroscopic analysis. The absolute configurations of the neolign ...

Abstract:
... A new lignan glucoside, galiveroside A (1), and seven known compounds (2–8), were isolated from Galium verum L. The structure of 1 was elucidated on the basis of extensive spectroscopic analyses. Compound 1, at the concentration of 5 mg/mL, showed insecticide activity to 3 age cotton bollworm with a mortality of 16.3% through stomach poisoning. When combined with a recombinant scorpion toxin rLqh ...

Abstract:
... Two new lignan-iridoid glucoside diesters (2 and 3), together with their putative biosynthetic precursor 10-O-trans-caffeoyl-6α-hydroxyl-dihydromonotropein (1), were characterized from the leaves of Vaccinium bracteatum. Their planar structures and relative configuration were elucidated by spectroscopic measurements and DFT C NMR calculations, and their absolute configurations were determined by t ...
