Plants collected from Limpopo province of South Africa were investigated for their antioxidative potential using the DPPH radical scavenging assay. Acetone extracts of Flueggea virosa had the highest antioxidant activity with an IC₅₀ value of 30 µg/ml, closely matching the ascorbic acid with an IC₅₀ value of 25 µg/ml. The lowest antioxidant readings were observed with extracts of Rhynchosia ven...

Weeksella virosa (formerly CDC group IIf) is a nonsaccharolytic, oxidase- and catalase-positive, gram-negative rod which is unable to grow on MacConkey agar.

A consecutive synthetic strategy was developed toward the total synthesis of securinega alkaloids. (-)-Norsecurinine was concisely assembled by addition of a methoxyallene to a ketone for efficient side-chain installation. Ring-closing metathesis was also utilized as a key step. The first total synthesis of (-)-niruroidine was achieved from (-)-norsecurinine in three steps, while the route to (...
