Spirostan

Spirostan is a class of phytosteroid that is characterized by a unique spiro ring structure in their chemical composition, composed by cross-bonded furan and pyran rings. Spirostan-type phytosteroids are commonly found in various plant species, such as fenugreek, yam, yucca and some species of Solanum, usually as glycosides. In such conjugated form, they are often named « steroidal saponins ». These compounds have been studied for their potential health benefits, including their ability to regulate cholesterol levels, enhance insulin sensitivity, and promote muscle growth. Some spirostan-type phytosteroids have also been shown to have anti-inflammatory and antioxidant properties. However, more research is needed to fully understand their effects and mechanisms of action.
