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-7α-methoxy-3β-ol, is a new steroid, and 2 , 4–15 were isolated from this plant for the first time.
