Abstract:
From the MeOH residue of Smallanthus sonchifolius stems and leaves, three new sesquiterpene derivatives, namely smallantholides A - C (1 - 3), and two know phenyl propanoid glycosides (4 and 5), were isolated using various chromatographic techniques. The structural elucidation was confirmed by spectroscopic methods including 1D, 2D NMR, CD and HR-TOF-MS. Moreover, the in vitro α-glucosidase inhibitory activity of 1 - 5 was also evaluated.
