Abstract Two new megastigmane glycosides, laurusides E-F ( 1 and 3 ) and three known ones ( 2 , 5 , and 7 ), together with a new abscisic acid glycoside, lauruside G ( 4 ) and a known one ( 6 ), were isolated from a methanolic extract of Laurus nobilis L. leaves using various chromatographic techniques. The structures of these compounds were fully characterized using a combination of spectroscopic techniques including multinuclear and multidimensional NMR and mass spectrometry. All of the isolat...

Abstract A phytochemical investigation for the constituents of the stems of Millettia dielsiana Harms ex Diels resulted in the isolation of a new isoflavone glycoside, mildiside A (1), and 14 known compounds (2–15). Their chemical structures were determined using a combination of IR, NMR, MS, and optical rotation analysis, as well as comparison with the literature data. The ethanolic (EtOH) extract and several isolated compounds exert the inflammatory effect of nitric oxide (NO) production in li...
