Sulfated Triterpene Glycosides from Zygophyllum Fabago

From the aerial parts of Zygophyllum fabago from Turkey, two new sodium salts of sulfated glycoside derivatives of ursolic acid, named as zygofaboside A (1) and zygofaboside B (2) have been isolated. Their structures were elucidated through spectral studies, including 2D-NMR spectroscopic experiments (HMQC, HMBC, COSY and NOESY).
