Sesquiterpene lactones (STLs) represent a diverse group ... The pathway typically commences with the conversion of farnesyl diphosphate into germacrene A via sesquiterpene synthases, followed ...

A new study published Monday in PNAS identified a key enzyme called farnesyl diphosphate (FPP) synthase, crucial for driving the reaction that creates a rose’s fresh and floral scent.

LREs presented mainly sesquiterpene lactones (SLs) and flavonoids. FGEs and ACEs presented mainly chlorogenic acids. SLs were not detected in GFEs but traces were detected in ACEs. All extracts ...
