“…12) Species of the genus Dryopteris are generally characterized by the presence of phloroglucinol derivatives, such as flavaspidic acids, triflavaspidic acids, dryocrassins, albaspidins and filixic acids. [13][14][15][16][17][18] Some of them showed anti-tumor promoting activity 19) and anti-bacterial activity. 20) Recently, kaempferol glycosides have been isolated from the Dryopteris species.…”

Three new kaempferol glycosides, called crassirhizomosides A (1), B (2) and C (3), were isolated from the rhizome of Dryopteris crassirhizoma (Aspidiaceae), together with the known kaempferol glycoside, sutchuenoside A (4). The structures of 1-3 were determined as kaempferol 3-alpha-L-(2,4-di-O-acetyl)rhamnopyranoside-7-alpha-L-rhamnopyranoside, kaempferol 3-alpha-L-(3,4-di-O-acetyl)rhamnopyranoside, and kaempferol 3-alpha-L-(2,3-di-O-acetyl)rhamnopyranosside-7-alpha-L-rhamnopyranoside, respectively, by chemical and spectroscopic means. Inhibitory effects of 1-4 and kaempferol on human immunodeficiency virus reverse transcriptase-associated DNA polymerase (RNA-dependent DNA polymerase and DNA-dependent DNA polymerase) and RNase H activities were investigated.
