Natural Product Identification
Common Name(-)-germacrene a
Description(-)-Germacrene A belongs to the class of organic compounds known as germacrane sesquiterpenoids. These are sesquiterpenoids having the germacrane skeleton, with a structure characterized by a cyclodecane ring substituted with an isopropyl and two methyl groups. (-)-germacrene a is found in Acanthospermum australe, Acorus calamus, Aristolochia gigantea, Dictyopteris divaricata, Eunicea mammosa, Eunicea succinea, Frullania tamarisci, Linzia glabra, Magnolia sieboldii, Mentha piperita, Nasutitermes torresi, Ocimum basilicum, Piper cernuum, Protium heptaphyllum, Prumnopitys ferruginoides, Rugelia nudicaulis, Saussurea costus and Tilesia baccata. (-)-germacrene a was first documented in 2022 (PMID: 36035671). Based on a literature review a small amount of articles have been published on (-)-germacrene A (PMID: 35723427) (PMID: 35696915) (PMID: 35630799).
