Description | Chlorflavonin is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Chlorflavonin is found in Acanthostigmella sp. and Apis cerana. It was first documented in 1969 (PMID: 5391291). Based on a literature review a significant number of articles have been published on Chlorflavonin (PMID: 23457022) (PMID: 4775434) (PMID: 5463573) (PMID: 29317534) (PMID: 29108416). |
