GLYCOSIDES ISOLATED FROM THE AERIAL PARTS OF Premna integrifolia L. GROWING IN THAI BINH

From the aerial parts of Premna integrifolia L., three glycosides acteoside ( 1 ), premnaodoroside A ( 2 ), and premnaodoroside B ( 3 ) were isolated. Their chemical structures were elucidated by means of ESI-MS, 1 H-NMR, 13 C-NMR, HSQC, HMBC spectra and in comparison with the previous literature. To our best knowledge, this is the first report of 1 and 3 from P. integrifolia .
