Shancigusins E-I, five new glucosides from the tubers of Pleione yunnanensis

Five new glucosides, shancigusins E‐I (1–5) were isolated from the tubers of Pleione yunnanensis (Rolfe) together with 18 known compounds. The structures of these compounds were determined by extensive analyses of their spectroscopic data. Copyright © 2013 John Wiley & Sons, Ltd. Five new glucos...

Zusammenfassung:	Five new glucosides, shancigusins E‐I (1–5) were isolated from the tubers of Pleione yunnanensis (Rolfe) together with 18 known compounds. The structures of these compounds were determined by extensive analyses of their spectroscopic data. Copyright © 2013 John Wiley & Sons, Ltd. Five new glucosides, shancigusins E‐I (1–5), were isolated from the tubers of Pleione yunnanensis (Rolfe) together with 18 known compounds. Their structures were determined by a combination of one‐ and two‐dimensional NMR techniques and mass spectrometry.
