Two new 9,10-seco-cycloartanes from the seeds of Sphaerophysa salsula

Abstract

Two new 9,10-seco-cycloartanes, named sphaerophyside SC (1) and sphaerophyside SD (2), together with four known compounds (3–6), were obtained from the ethanol extract of the seeds of Sphaerophysa salsula. The structures of these compounds were elucidated on the basis of spectral and chemical evidences. Compounds 3–6 were isolated from the plant for the first time.
