Abstract: Abstract From the crude glycoside of root of Cynanchwn forrestii Schltr, besides one known C21 steroidal glycoside-cynatratoside-B( I ), a new C21 steroidal glycoside named cynaforroside-A( I) was isolated. On the basis of its spectral and chemical evidence, the new compound was deduced as glaucogenin C 3-0-α-L-cymaropyranosyl-( 1→4 )-β-L-cymaropyranosyl-( 1→4 )-β-D-oleandropyranosidc.
