Metabolite Identification
Common NameAloeemodin
DescriptionAloeemodin, also known as rhabarberone or rottlerin?, belongs to the class of organic compounds known as anthraquinones. These are organic compounds containing either anthracene-9,10-quinone, 1,4-anthraquinone, or 1,2-anthraquinone. Thus, aloeemodin is considered to be an aromatic polyketide. Aloeemodin 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. Based on a literature review a significant number of articles have been published on Aloeemodin.
