Chionaeosides A-D, triterpene saponins from Paronychia chionaea
Avunduk, Sibel; Lacaille-Dubois, Marie-Aleth; Miyamoto, Tomofumi; Bedir, Erdal; Şenol, Serdar Gökhan; Çalışkan, Özgen Alankuş (Amer Chemical Soc, 2007)Four new triterpenoid saponins, chionaeosides A-D (1-4) were isolated from the roots of Paronychia chionaea. On the basis of their spectroscopic data, the structures of the new saponins were established as 3-o-alpha-L-ar ... -
Cycloartane Glycosides from Three Species of Astragalus (Fabaceae)
Linnek, Jens; Mitaine-Offer, Anne-Claire; Miyamoto, Tomofumi; Tanaka, Chiaki; Paululat, Thomas; Avunduk, Sibel; Lacaille-Dubois, Marie-Aleth (Wiley-V C H Verlag Gmbh, 2011)Nine cycloartane-type glycosides were isolated from three species of the genus Astragalus (Fabaceae): From the aerial parts of A. cicer L., two new saponins, cicerosides A and B (1 and 2, resp.), i.e., a tetradesmosidic ... -
Cycloartane-Type Saponins from Astragalus tmoleus var. tmoleus
Avunduk, Sibel; Mitaine-Offer, Anne-Claire; Miyamoto, Tomofumi; Tanaka, Chiaki; Lacaille-Dubois, Marie-Aleth (Sage Publications Inc, 2016)Five known cycloartane-type glycosides were isolated from the roots of A. tmoleus Boiss. var. tmoleus. The identification of these compounds was mainly achieved by 1D and 2D NMR spectroscopic techniques and FABMS. The ... -
Secondary Metabolites from the Roots of Paronychia chionaea
Avunduk, Sibel; Alankus-Caliskan, Ozgen; Miyamoto, Tomofumi; Tanaka, Chiaki; Lacaille-Dubois, Marie-Aleth (Natural Products Inc, 2011)Two novel secondary metabolites, compounds (1-2) were isolated from the roots of Paronychia chionaea. On the basis of spectroscopic data including ID and 2D NMR experiments (COSY, TOCSY, HSQC, and HMBC), and mass spectroscopy, ... -
Triterpene glycosides from the roots of Astragalus flavescens
Avunduk, Sibel; Mitaine-Offer, Anne-Claire; Alankuş-Caliskan, Özgen; Miyamoto, Tomofumi; Şenol, Serdar Gökhan; Lacaille-Dubois, Marie-Aleth (Amer Chemical Soc, 2008)Six new triterpene saponins, 3-O-alpha-L-rhamnopyranosyl-(1 -> 2)-beta-D-Xylopyranosyl-(1 -> 2)-beta-D-glucuronopyranosyl-21-epi-kudzusapogenol A (1), 3-O-alpha-L-rhamnopyranosyl-(1 -> 2)-beta-D-glucopyranosyl-(1 -> ... -
Triterpenoid saponins from the roots of two Gypsophila species
Pertuit, David; Avunduk, Sibel; Mitaine-Offer, Anne-Claire; Miyamoto, Tomofumi; Tanaka, Chiaki; Paululat, Thomas; Lacaille-Dubois, Marie-Aleth (Pergamon-Elsevier Science Ltd, 2014)Two triterpenoid saponins with two known ones have been isolated from the roots of Gypsophila arrostii var. nebulosa, and two new ones from the roots of Gypsophila bicolor. Their structures were established by extensive ...
