Natural Product Identification
Common Nameazadirachtin h
DescriptionAzadirachtin H 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. azadirachtin h is found in Azadirachta indica. azadirachtin h was first documented in 2003 (PMID: 12822931). Based on a literature review a small amount of articles have been published on azadirachtin H (PMID: 35480004) (PMID: 16038546) (PMID: 17428489).
