Certainly neither type uses red coloration as advertisement to attract the seed dispersing agents. Fleshy-fruited species (Rhamnus alaternus, Rubus sanguineus...
متن کاملComparison of pancreatic lipase inhibitory isoflavonoids from unripe and ripe fruits of Cudrania tricuspidata
The composition and content of the active constituents and their biological activity vary according to diverse factors including their maturation stages. A previous study showed that the fruits of Cudrania tricuspidata inhibited pancreatic lipase activity, a key enzyme in fat absorption. In this study, we investigated the chemical composition and pancreatic lipase inhibitory activity of unripe ...
متن کاملPhytochemical differences between Calia secundiflora (Leguminosae) growing at two sites in Mexico.
The ecology and quinolizidine alkaloid chemistry of Calia secundiflora (Ortega) Yakovlev growing at two sites in Mexico were compared. At one site (Hidalgo) the vegetation was dominated by Flourensia resinosa and C. secundiflora, at the other site (Queretaro) C. secundiflora and Dodanaea viscosa were dominant. The Hidalgo site had shallower soils with less organic matter, N, P, and CaCO3. Seeds...

متن کاملIsolation and identification of alkaloids from fruits of Berberis thunbergii DC
Two major bisbenzylisoquinoline alkaloids, isotetrandrine and berbamine and three protoberberine type alkaloids berberine, palmatine, and jatrorrhizine were isolated from seeds of Berberis thunbergii DC. Berberine and oxyberberine, which is not present in the seeds, were isolated from the pericarp. Identity of the isolated substances was verified by spectral means (i.r., u.V., and mass spectrom...
