Common Name(5R,6S)-5,6-Epoxy-7-megastigmen-9-one
Description(5R,6S)-5,6-Epoxy-7-megastigmen-9-one belongs to the class of organic compounds known as oxepanes. Oxepanes are compounds containing an oxepane ring, which is a seven-member saturated aliphatic heterocycle with one oxygen and six carbon atoms (5R,6S)-5,6-Epoxy-7-megastigmen-9-one is a sweet, berry, and fruity tasting compound (5R,6S)-5,6-Epoxy-7-megastigmen-9-one has been detected, but not quantified in, watermelons (Citrullus lanatus). This could make (5R,6S)-5,6-epoxy-7-megastigmen-9-one a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on (5R,6S)-5,6-Epoxy-7-megastigmen-9-one.
