Anti-oxidant and anti-diabetic activities of Lespedeza cuneata water extract

Oxidative damage induced by free radicals are the attendant causes of many chronic diseases. The purpose of this study was to investigate whether Lespedeza cuneata water extract (LCW) has anti-oxidant and anti-diabetic activities in vitro. Anti-oxidant activity was measured by superoxide anion (O2-), hydroxyl (·OH) radical, nitric oxide (NO) and peroxynitrite (ONOO-) scavenging assays. Further, radical-mediated...

Secretory structures in Cochlospermum regium (Schrank) Pilg. (Bixaceae): Distribution and histochemistry

Cochlospermum regium (Schrank) Pilg., known as the yellow cotton tree, is a small shrub with a number of pharmacological properties. A series of chemical compounds produced by the plant may be associated with secretory cells and tissues, such as idioblasts, trichomes and ducts. Thus, the aim of this study was to identify the secretory structures and major classes of compounds in vegetative organs of C. regium. Leaf,...
