Anthraquinones of the Roots of Pentas micrantha [PDF]

Molecules, 2012
Pentas micrantha is used in the East African indigenous medicine to treat malaria. In the first investigation of this plant, the crude methanol root extract showed moderate antiplasmodial activity against the W2- (3.37 μg/mL) and D6-strains (4.00 μg/mL) of Plasmodium falciparum and low cytotoxicity (>450 μg/mL, MCF-7 cell line).

Defect Engineering on Commercial Carbon for Economical H2O2 Electrosynthesis Under Industrial‐Relevant Conditions

Advanced Functional Materials, EarlyView.
The implementation of electrocatalysts toward H2O2 electrosynthesis on an industrial scale necessitates the reconsideration of design criteria. The proposed “active sites saturation” theory shows that materials with mixed active sites normally exhibit low selectivity under practical conditions.
