| Description | Violet-leaf aldehyde, also known as (2E,6Z)-2,6-nonadienal or cucumber aldehyde, belongs to the class of organic compounds known as medium-chain aldehydes. These are an aldehyde with a chain length containing between 6 and 12 carbon atoms. Thus, violet-leaf aldehyde is considered to be a fatty aldehyde. Violet-leaf aldehyde is a cucumber, dry, and fatty tasting compound. Violet-leaf aldehyde is found, on average, in the highest concentration within red wine. Violet-leaf aldehyde has also been detected, but not quantified in, several different foods, such as mollusks, muskmelons (Cucumis melo), herbal tea, red tea, and breakfast cereal. This could make violet-leaf aldehyde a potential biomarker for the consumption of these foods. Violet-leaf aldehyde 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 Violet-leaf aldehyde. |
