Natural Product Identification
Common NameRubescin K
DescriptionRubescin K belongs to the class of organic compounds known as limonoids. These are highly oxygenated, modified terpenoids with a prototypical structure either containing or derived from a precursor with a 4,4,8-trimethyl-17-furanylsteroid skeleton. All naturally occurring citrus limonoids contain a furan ring attached to the D-ring, at C-17, as well as oxygen containing functional groups at C-3, C-4, C-7, C-16 and C-17. Based on a literature review very few articles have been published on Rubescin K.
