A new glycoside, brachynoside, isolated from Clerodendron brachyanthum Schauer

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.

A new phenylpropanoid glycoside has been isolated from the methanolic extract of the aerial parts of Stachys lavandulifolia (Lamiaceae), lavandulifolioside (1).On the basis of chemical and spectral data the structure of the new compound 1 has been elucidated as β-(3,4-dihydroxyphenyl)ethyl O-α-L-arabinopyranosyl-(1->2)-α-L-rhamnopyranosyl-(1->3)-4-O-caffeoyl-β-D-glucopyranoside.

PHENYLPROPANOID GLYCOSIDES ISOLATED FROM SCROPHULARIA SCOPOLI

Key Word Index - Scrophularia scopolii var. scopolii; Scrophulariaceae; phenylpropanoid glycosides; acteoside; verbascoside; angoroside A; deacyl angoroside A dimethyl ether; deacyl acteoside dimethyl ether. A new phenylpropanoid glycoside, angoroside A, and a known glycoside, acteoside, were isolated from the roots of Scrophularia scopolii var. scopolii.On the basis of chemical and spectral evidence, angoroside A was shown to be 3,4-dihydroxy-β-phenylethoxy-O-α-L-arabinopyranosyl-(1->6)-α-L-rhamnopyranosyl-(1->3)-4-O-caffeoyl-β-D-glucopyranoside.

IRIDOID AND PHENOLIC GLYCOSIDES FROM HARPAGOPHYTUM PROCUMBENS

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.
