DescriptionKhellin, also known as quelina or khelloyd, belongs to the class of organic compounds known as furanochromones. These are polycyclic aromatic compounds containing a furan ring fused to a 1-benzopyran-4-one ring system. Thus, khellin is considered to be an aromatic polyketide. Khellin is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Khellin is found in Allium nutans, Dioscorea deltoidea and Dioscorea parviflora. Khellin was first documented in 2003 (PMID: 12880095). Based on a literature review a small amount of articles have been published on Khellin (PMID: 19639121) (PMID: 21069311) (PMID: 24069365).
