Abstract
An extract from the rhizomes of Cassumunar ginger (Zingiber purpureum Roscoe). was found to have significant α-glucosidase inhibitory activity with an IC50 value of 6.3 µg/mL. Two new phenylbutenoids, cassudimin A (1) and cassumunol N (2), and seven known compounds (3-9) were isolated. Their structures and relative configurations of two new compounds were elucidated based on spectra interpretation. Compounds 1-3, 6-9 showed more potent α-glucosidase inhibitory activity than a positive control, acarbose (IC50 = 168.0 µM). Dehydrozingerone (6) exhibited the most potent α-glucosidase inhibition with an IC50 value of 8.3 μM. Compounds 7 and 9 were found in Z. purpureum rhizomes for the first time.
