Chemische und Chemotaxonomische Untersuchungen von Filices. XL. Chemische Untersuchungen der Inhaltsstoffe von Microlepia marginata (Panzer) C. CHR.

From the fronds of Microlepia marginata (Panzer) C.Chr. five new ent-kaurane type diterpene glycosides, microlepin(I), 17-O-acetylmicrolepin(VIII), 6'-O-acetylmicrolepin(IX), 4-epi-microlepin(X) and 6'-O-α-L-rhamnopyranosyl-4-epi-microlepin(XVIII) were isolated and their structures were elucidated by spectroscopic methods and some chemical reactions.Microlepin and 4-epi-microlepin possesses the structures 16α,17,19-trihydroxy-ent-kaurane 19-O-β-(4'-O-methyl)-D-glucopyranoside and 16α,17,18-trihydroxy-ent-kaurane 18-O-β-(4'-O-methyl)-D-glucopyranoside.
