Active metabolites of the genus Piper against Aedes aegypti: natural alternative sources for dengue vector control
TL;DR: This review assesses a naturally occurring plant matrix and pure compounds of the Piper species, which have been shown to be active against Aedes aegypti, which is one of the most important mosquito-borne viral diseases in the world.
Journal ArticleDOI
The stereochemistry of ledol from Renealmia chrysotrycha: an NMR study
TL;DR: From the leaves of Renealmia chrysotrycha (Zingiberaceae), a sesquiterpene alcohol was isolated for which spectral data suggested the structure of a 10-aromadendranol, establishing its relative stereochemistry as that of ledol.
