Steroidal lactones represent a diverse class of natural compounds characterized by a steroid backbone fused with a lactone ring, commonly found in plants such as Withania somnifera. They include withanolides like withaferin A and withanolide D. These compounds exhibit adaptogenic, anti-inflammatory, and potential anticancer properties. Due to structural variability, specific physicochemical constants differ widely across members of the class. They are studied for pharmacological applications but lack uniform properties as a single entity.
