Neolignan glucosides from Phlomis chimerae Boiss.
From the aerial parts of the plant Phlomis chimerae, a new neolignan glucoside, (-)-4-O-methyldihydrodehydrodiconiferyl alcohol-9'-O-beta-D-glucopyranoside (1) was characterized along with the known neolignan glucosides, (-)-4-O-methyldehydrodiconiferyl alcohol-9'-O-beta-D-glucopyranoside (= longifloroside A) (2) and (-)-dihydrodehydrodiconiferyl alcohol-9-O-beta-D-glucopyranoside (3). The stru...
متن کاملIridoid glucosides from Phlomis tuberosa L. and Phlomis herba-ventis L.
A new iridoid glucoside, 5-desoxysesamoside, was isolated from Phlomis tuberosa L. (Lamiaceae) together with three known iridoid glucosides sesamoside, shanziside methyl ester and lamalbid. Lamiide was found in P. herba-ventis ssp. pungens in high concentrations.
متن کاملIsolation of lignan glucosides and neolignan sulfate from the leaves of Glochidion zeylanicum (Gaertn) A. Juss.
Six lignan and neolignan derivatives (1-6) were isolated from the n-BuOH-soluble fraction of a MeOH extract of the leaves of Glochidion zeylanicum. On the basis of spectral data, their structures were elucidated to be (+)-isolarisiresinol 3a-O-beta-glucopyranoside (1), dihydrodehydrodiconiferyl alcohol 4-, 9- and 9'-O-beta-D-glucopyranosides (2-4, respectively), (+)-isolarisiresinol 2a-O-beta-D...
متن کاملDNA damage protection against free radicals of two antioxidant neolignan glucosides from sugarcane molasses.
BACKGROUND Sugarcane molasses is a potential by-product of the sugarcane manufacturing industry that is rich in antioxidant materials. The present study aimed to obtain antioxidative compounds from sugarcane molasses and to evaluate their ability to protect DNA from oxidative damage. RESULTS Two neolignan glucosides were isolated from sugarcane molasses using bioassay and UV spectra monitorin...
