TWO NEW SESQUITERPENE COUMARINS, FERUSINOL AND SAMARCANDIN DIASTEREOMER FROM FERULA SINAICA

Re-investigation of the CH2Cl2:CH3OH (1:1) extract of the roots of Ferula sinaica resulted in the isolation of ferusinol, a new sesquiterpene coumarin with a rare carbon skeleton, and samarcandin diastereomer. The Structures of the isolated compounds were determined by MS, 1H, 13C- 1D and 2D NMR spectral analysis.
