Two glycosides were isolated from the n-Butanol soluble portion of the ethanolic portion of the stem and leaves part of stachytarpheta angustifolia. Their structures were elucidated as Iridoid glycoside (1) and a caffeic glycoside ester named as –β(3 1 , 4 1 dihydroxyphenyl)–ethyl-O-α-L-rhamnopyranosyl-(1-3)-β-D-(4-O-Caffeoyl) glucopyranoside (2) by spectroscopic Method.

Thirteen pregnane glycosides were isolated from fresh leaves of Marsdenia tomentosa collected in the Fukuyama district. Of these, six were glycosides previously obtained from the same plant collected in the Fukuoka district and one from another Asclepiadaceous plant. The structures of the six new glycosides were determined by spectrometric method.
