Abstract

Ficus vallis-choudae Delile has been reported to exhibit antifungal, anticonvulsant, anti-inflammatory and antinociceptive activities. Herein we report the first ever pharmacochemical studies on the figs of Ficus vallis-choudae resulting in isolation of a new ceramide named nkwenamide (1). Also, seven known compounds including the binary mixture of β-amyrin palmitate (2) and lupeol palmitate (3), olean-12-en-3-one (4), n-hexacosan-1-ol (5), β-sitosterol (6), and mixture of β-amyrin (7) and lupeol (8) were isolated. Their structures were elucidated using spectroscopic methods. The methanol extract of the figs of this plant exhibited urease, and α-glucosidase activities and showed DPPH radical scavenging potency with IC50 values, 61.7, 73.7 and 87.4 µg/mL, respectively. It also showed a weak chemiluminescence activity as compared to ibuprofen. The mixture of 2 and 3 exhibited maximum urease inhibitory activity with IC50 value 23.9 µg/mL while the mixture of 7 and 8 showed the maximum α-glucosidase inhibition with IC50 value 44.0 µg/mL. All the isolates showed weak chemiluminescence activity.
