DescriptionHalosterol b belongs to the class of organic compounds known as stigmastanes and derivatives. These are sterol lipids with a structure based on the stigmastane skeleton, which consists of a cholestane moiety bearing an ethyl group at the carbon atom C24. Thus, halosterol b is considered to be a sterol. halosterol B is found in Haloxylon recurvum. halosterol B was first documented in 2006 (PMID: 16651755). Based on a literature review very few articles have been published on Halosterol b.
