Five new hopane derivatives, viz. 22, 28-epoxyhopane (1), 22, 28-epoxyhopan-30-ol (2), hopane-22, 30-diol (3), hop-22(29)-en-30-ol (4) and hop-22(29)-en-28-ol (5), were isolated along with other known triterpenoids from the rhizomes of Pyrrosia lingua. Their structures were elucidated by detailed two dimensional-NMR analysis.
