, p. 1928 - 1929 (1992)
Eudesmin, syringaresinol dimethyl ether, kusaginin and brachynoside were isolated from the ethanol extract of the leaves of Clerodendron brachyanthum. The new glycoside, branchynoside, was assigned as 2-(3,4-dimethoxyphenyl)ethyl 3-O-α-L-rhamnopyranosyl-4-O-(3,4-dihydroxycinnamoyl)-β-D-glucopyrano side from studies on partial methylation and methanolysis products and from analysis of spectroscopic evidence.

Key Word Index - Harpagophytum procumbens; Pedaliaceae; iridoid and phenolic glycosides; synthesis.A novel bioside, β-(3',4'-dihydroxyphenyl)ethyl-O-α-L-rhamnopyranosyl(1 -> 3)-β-D-glucopyranoside, was obtained from the secondary roots of Harpagophytum procumbens.It is accompained by the known iridoid glucosides harpagoside, procumbide, and its 6'-O-p-coumaroyl ester, and phenolic glycosides, acteoside and isoacteoside, the latter pair being obtained from H. procumbens for the first time.The structures of these metabolites were differentiated by high resolution NMR studies, while that of the bioside is additionally supported by synthesis.
