Seven iridoid glycosides (I-VII) have been isolated from Cistanchis Herba, the whole plant of Cistanche salsa (C. A. MEY.) G. BECK (Orobanchaceae). The structure of a new compound, 6-deoxycatalpol (V), and the identity of the other glycosides have been established by chemical transformations and spectral analyses of the compounds and their derivatives. Mussaenosidic acid (I) was isolated for the first time as a natural product.
