From the fronds of five pteridaceous ferns , several 1-indanone-type sesquiterpenes (pterosins and pterosides) were isolated.Four of them, isolated from M. speluncae were new and were assigned the structures 13-hydroxy-3(R)-pterosin D (V), 13-hydroxy-3(R)-pterosin D 3-O-α-L-arabinopyranoside (VI), 3(R)-pterosin D 3-O-α-L-arabinopyranoside (VIII) and 2(R),3(R)-pterosin L 3-O-α-L-arabinopyranoside (XI).The structures were elucidated mainly by spectroscopic methods.Compound V was named spelosin.The investigation of two other species, M. calvescens (WALL.) PRESL and M. okamotoi TAGAWA, gave no identifiable compounds, of this type.Keywords--Microlepia speluncae; Microlepia trapeziformis; Microlepia obtusiloba; Microlepia substrigosa; Microlepia strigosa; Microlepia calvescens; Microlepia okamotoi; Pteridaceae; chemotaxonomy; pterosin-type sesquiterpene
