Abstract Cirrhopetalidin and cirrhopetalinin, two new bibenzyl derivatives, and 3,3′-dihydroxy-5-methoxybibenzyl (batatasin-III) were isolated from the orchidCirrhopetalumandersonii . The structures of the new bibenzyls were established as 2′,3-dihydroxy-3′-methoxy-4,5-methylenedioxybibenzyl and 3,3′-dihydroxy-4,5-methylenedioxy-bibenzyl, mainly from spectral evidence.
