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.
