Cyclohopenol (1) and cyclohopanediol (2), two hexacyclic hopane derivatives, were isolated along with hop-22(29)-en-28-al (3) from the rhizomes of Pyrrosia lingua. They were characterized as (28S)-28, 29-cyclohop-22(30)-en-28-ol and (22R, 28S)-28, 29-cyclohopane-22, 28-diol, respectively, on the basis of spectral analyses.
