Steroids and triterpenoids from Cucumis sativus roots

Investigations on the EtOH extract of Cucumis sativus roots led to the isolation of 15 compounds (1-15). Their structures were identified using spectroscopic methods. Among these compounds, compound 1, stigmasta-8(14),22-diene-7 alpha-methoxy-3 beta-ol, is a new steroid, and 2, 4-15 were isolated from this plant for the first time.
