Provided ByJEOL DatabaseJEOL Logo
DescriptionTopsentisterol B4 belongs to the class of organic compounds known as ergostane steroids. These are steroids with a structure based on the ergostane skeleton, which arises from the methylation of cholestane at the 24-position. topsentisterol B4 is found in Topsentia sp. topsentisterol B4 was first documented in 2006 (Luo, X., et al.). Based on a literature review very few articles have been published on Topsentisterol B4.
