The reinvestigation of Microlepia marginata (PANZER) C.CHR. afforded in addition to the previously reported ent-kaurane glycosides three new ent-pimarene derivatives, which were named fumotoshidin A (I), B (II) and C(III).The stuctures of the new compounds were characterized by spectroscopic methods and some chemical transformations as 2β,15(R),16-trihydroxy-ent-pimar-7-en-3-one (I), 3α,15(R),16-trihydroxy-ent-pimar-7-en-2-one (II) and 2,15(R),16-trihydroxy-ent-pimar-1,7-dien-3-one (III).Keywords - Microlepia marginata; fern; chemotaxonomy; ent-pimar-7-ene derivative; spectroscopic method; chemical transformation
