✦ Synopsis

Six new furanoid diterpenc glucosides, named palmatoside B(1). .C(2). D(3). E(4). F(5). and G(6)

were isolated from the dried roots of Jnrrorhira palntafct Miers (Colombo root). The structures were clucidatcd by chemical and spectroscopic evidence to bc do-(& 1)-glucopyranosyl)chasmanthin, 4-U-(~-D-glucopyranosyl)columbin. 4-0-(fi-D-glucopyranosyl)isocolumbin, CO-(&D-glucopyranosyl)isojateorin. 4-U-(p-D-glucopyranosylrjateorin, and [2S-( 2 x4au.6ap.l Oap.1 Obu)]-,-( 3-furanyl)-6a-(~-~-ghcopyranosy~-1) x y met h y I )-
