Özet

From the herb of Galium fissurense, a new flavanone glucoside was isolated and characterized as 5,7,3'-trihydroxyflavanone-4'-O-beta-D-glucopyranoside (1) from spectroscopic evidence. In addition, three known compounds (luteolin, apigenin-7-O-beta-D-glucopyranoside, naringenin-7-O-beta-D-glucopyranoside) were isolated for the first time from this plant. The free radical scavenging properties of the four compounds were studied by use of in vitro electron spin resonance spectrometry. The new compound showed potent antioxidant activity.
