A roselle (Hibiscus sabdariffa Linn.) tea extract was found to have high inhibitory activity against porcine pancreatic α-amylase and was compared to that of structurally related citric acid, a previously known inhibitor of fungal α- amylase.
Apoptosis-Inducing Effect of Fucoxanthin on Human Leukemia Cell Line HL-60
The apoptosis-inducing effect of fucoxanthin on human leukemic HL-60 cells was investigated and it was suggested that a carotenoid structure might be crucial for inducing apoptosis.
Isolation and Identification of α-Glucosidase Inhibitors from Tochu-cha (Eucommia Ulmoides)
alpha-Glucosidase inhibitory activity was found in aqueous methanol extracts of tochu-cha, dried leaves of Eucommia ulmoides (Eucommiaceae) and quercetin was considered to contribute mostly to the activity of the tochu leaves.
