Acetylated Flavanone Glycosides from the Rhizomes of Cyclosorus acuminatus

Six new flavanone glycosides (1−6) were isolated from the methanol extract of the rhizomes of Cyclosorus acuminatus, together with the parent flavanone glycoside 2a. Their structures were established on the basis of spectroscopic and chemical methods. All compounds showed moderate activity against S...

Zusammenfassung:	Six new flavanone glycosides (1−6) were isolated from the methanol extract of the rhizomes of Cyclosorus acuminatus, together with the parent flavanone glycoside 2a. Their structures were established on the basis of spectroscopic and chemical methods. All compounds showed moderate activity against Streptococcus pneumoniae and Haemophilus influenzae.
