title: Furanoterpenoids from Siphonochilus aethiopicus.
abstract: Two new furanoterpenoid derivatives, namely 4a alpha H-3,5 alpha,8 alpha beta-trimethyl-4,4a,9-tetrahydro-naphtho[2,3-b]-furan-8-one and 2-hydroxy-4a alpha H-3,5 alpha, 8a beta-trimethyl-4,4a,9-tetrahydronaphtho[2,3-b]-furan-8-one, were isolated from Siphonochilus aethiopicus, a member of the family Zingiberaceae. Their structures were elucidated using high field NMR techniques.
