Phenylpropanoid derivatives from edible canna, Canna edulis.
TLDR
Two phenylpropanoid sucrose esters were isolated from dry rhizomes of Canna edulis Ker Gawl and on the basis of analysis of spectroscopic data and chemical evidence, they were shown to be 3-O-p-coumaroyl-6- O-feruloyL-beta-D-fructofuranosyl 6-O -acetyl-alpha-D -glucopyranoside. Expand
Methyl Caffeate as an α-Glucosidase Inhibitor from Solanum torvum Fruits and the Activity of Related Compounds
TLDR
Methyl caffeate has a most favorable structure for both sucrase and maltase inhibition, except for a higher activity of methyl 3,4,5-trihydroxycinnamate against suCrase, which provides a prospect for antidiabetic usage of S. torvum fruit. Expand
