Iridoid glycoside constituents of Stachys lanata.
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.
