Iridoid and phenylethanoid glycosides from Phlomis tuberosa L.
A new iridoid glucoside, 8-O-acetylshanzhiside (1), was isolated from the aerial parts of Phlomis tuberosa, together with two known iridoid glucosides, shanzhiside methyl ester and lamalbide. The known phenylethanoid glycosides acteoside and forsythoside B were also obtained and characterized. The structure of 1 was determined by means of 1D- and 2D-NMR spectroscopic evidence.
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 کاملRapid Identification of α-Glucosidase Inhibitors from Phlomis tuberosa by Sepbox Chromatography and Thin-Layer Chromatography Bioautography
Alpha-glucosidase inhibitors currently form an important basis for developing novel drugs for diabetes treatment. In our preliminary tests, the ethyl acetate fraction of Phlomis tuberosa extracts showed significant α-glucosidase inhibitory activity (IC₅₀ = 100 μg/mL). In the present study, a combined method using Sepbox chromatography and thin-layer chromatography (TLC) bioautography was develo...
متن کاملNovel Nortriterpenes from Phlomis umbrosa.
We isolated 8 novel 28-noroleanane-derived spirocyclic triterpenoids with unusual skeleton structures, phlomisone (1), phlomistetraol A (2), phlomistetraol B (3), phlomistetraol C (4), phlomispentaol (5), phlomishexaol A (6), phlomishexaol B (7), and phlomisin (8), from the ethanol extract of Phlomis umbrosa rhizomes. Their structures were elucidated on the basis of spectroscopic methods, inclu...
متن کاملPhenolic Constituents from Phlomis lycia
There are 34 Phlomis L. species (Labiatae) growing in Turkey. Some Phlomis species are used as tonics and stimulants in Anatolia . During our systematic phytochemical investigations of Phlomis species we have studied P. linearis Boiss. & Bal.3−6, Phlomis armeniaca Willd., Phlomis pungens Willd. var. pungens 8−10, Phlomis pungens Willd. var. hirta Velen, Phlomis bourgaei Boiss., and Phlomis long...
