Abstract
A new lignan, (+)-nortrachelogenin (I), and a known compound, daphnoretin were isolated from Wikstroemia indica C.A. Meyer (Thymelaeaceae). The structure of (+)-nortrachelogenin was established as 8(R)8'-4,4',8'-trihydroxy-3,3'-dimethoxylignan-olid, (9,9') on the basis of spectroscopic evidence and comparison with its enantiomer, (-)-nortrachelogenin. +-nortrachelogenin(I) showed effects on the central nervous system producing depression in rabbits.
