Abstract
Four new tetrahydrofuran-type sesquilignans, named bonaspectin A, bonaspect in B, bonaspectin C 4 "-beta-glucoside and bonaspectin D 4 "-beta-glucoside , as well as two new 8.O.4'-type sesquineolignans, named neobonaspectin A a nd B. were isolated from the aerial vegetative parts of Bonamia spectabilis (Convolvulaceae), together with the known compound rel-(7S,8S,7'R,8'R)-3,3 ',4,4',5,5'-hexamethoxy-7.O.7',8.8'-lignan. Their structures were establish ed on the basis of spectral data. (C) 2000 Elsevier Science Ltd. All rights reserved.
