Chemical and chemotaxonomical studies on Dicranopteris species.
Clerodane glycosides and flavonoids in Dicranopteris pedata and three varieties of D. linearis were investigated. All the ferns contained a new glycoside, (6S,13S)-6-[6-O-acetyl-beta-D-glucopyranosyl-(1-->4)-alpha-L-rhamnopy - ranosyloxy]-13-[alpha-L-rhamnopyranosyl-(1-->4)-beta-D-fucopyra nosyloxy]- cleroda-3,14-diene, as a chemical marker of this group. Flavonoids were limited to flavonol 3-O-glycosides. The ferns and isolated flavonoids are as follows; D. pedata: afzelin, quercitrin. D. linearis var. brevis: afzelin, quercitrin. D. linearis var. tenuis: quercitrin, isoquercitrin. D. linearis var. sebastiana: astragarin, isoquercitrin, rutin, kaempferol 3-O-(4-O-p-coumaroyl-3-O-alpha-L-rhamnopyranosyl)-alpha-L-rhamn opy ranosyl- (1-->6)-beta-D-glucopyranoside.
