Sesquiterpene Lactones from Elephantopus scaber
The ethanolic and acetone extracts of the whole plant of Elephantopus scaber were found to contain ethyl hexadecanoate, ethyl-9,12-octadecadienoate, ethyl-(Z)-9-octadecenoate, ethyl octadecanoate, lupeol, stigmasterol, stigmasterol glucoside, deoxyelephantopin (1) and two new germacranolide sesquiterpene lactones named 17,19-dihydrodeoxyelephantopin (2)

Terpenes and Terpenoids: How can we use them?
The transition from petroleum‐based to renewable bio‐based chemicals has led to increased interest in terpenes and terpenoids. This overview highlights their chemistry, focusing on their reactivity and applications in polymerizations, total syntheses, pharmaceuticals, and bio‐based chemical conversions; promoting sustainable and green chemical ...

Natural fumigation as a mechanism for volatile transport between flower organs [PDF]
Plants synthesize volatile organic compounds (VOCs) to attract pollinators and beneficial microorganisms, to defend themselves against herbivores and pathogens and for plant-plant communication. Generally, accumulation and emission of VOCs occur from the tissue of their biosynthesis.

We report the first high‐quality chromosome‐level genome assembly for the aphid Uroleucon formosanum, a serious pest that infests lettuce in eastern Asia. A combination of comparative genomic analyses and RNA‐seq transcriptome profiling suggests that U. formosanum employs integrative mechanisms to cope with host plant‐derived sesquiterpene lactone (STL)
