The increase in the number of consumers who produce part of their own electricity through photovoltaic distributed generation (PVDG) led to the need for studies on how the power system is affected. As the distribution systems were not designed to int

Bioassay-guided fractionation of dichloromethane extract from Athenaea velutina leaves led to the isolation of three withanolides, all being reported for the first time in this species. They were identified as withacnistin (1), withacnistin acetate (
