Iridoid Glycoside Constituents of Stachys lanata

Journal of Natural Products, 2008
From the aerial parts and roots of Stachys lanata, four new iridoid glucosides, stachysosides E-H (1-4), were isolated together with 30 known compounds. The structures and the stereo configurations of these new compounds were elucidated on the basis of the results of spectroscopic analysis. Compounds 1-4 are esters of monomelittoside.

Iridoid glycosides ofVerbascum saccatum

Chemistry of Natural Compounds, 1983
An aqueous solution of a methanolic extract of the epigeal part ofVerbascum saccatum C. Koch (1.4 kg) was washed with organic solvents and chromatographed on columns of alumina, polyamide, and silica gel, leading to the isolation of 3.6 g of a new iridoid glycoside — saccatoside (I) — in the form of an amorphous substance with [α] D 20 −200±2.5° (c 0.2;

Three phenylethanoid glycosides and an iridoid glycoside from Picrorhiza scrophulariiflora

Phytochemistry, 1998
Three new phenylethanoid glycoside, named scrosides A-C and a new iridoid glycosides, named picroside IV, have been isolated from the underground parts of Picrorhiza scrophulariiflora, together with 11 known compounds. Their structures were elucidated by the means of 2D NMR spectroscopy and chemical methods.
