Abstract
The structures of six new C-20 quassinoids and one new C-19 quassinoid, all isolated from the twigs and thorns of Castela polyandra, were established by a combination of spectroscopic and single-crystal X-ray analysis. Five k nown quassinoids and one known sterol were also identified. (C) 1998 Elsevi er Science Ltd. All rights reserved.
