DescriptionBrassinolide belongs to the class of organic compounds known as brassinolides and derivatives. These are cholestane based steroid lactones containing benzo[c]indeno[5,4-e]oxepin-3-one. Thus, brassinolide is considered to be a sterol. Brassinolide has been detected, but not quantified in, several different foods, such as common grapes (Vitis vinifera), almonds (Prunus dulcis), flaxseeds (Linum usitatissimum), cloves (Syzygium aromaticum), and mandarin orange (clementine, tangerine). This could make brassinolide a potential biomarker for the consumption of these foods. Brassinolide is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. 24-epibrassinolide is found in Brassica campestris , Thea sinensis , Gypsophila perfoliata, Helianthus annuus and Senna tora. 24-epibrassinolide was first documented in 2021 (PMID: 34333543). Based on a literature review very few articles have been published on Brassinolide (PMID: 34295316).
