In vitro anti-rotavirus activity of polyphenol compounds isolated from the roots of Glycyrrhiza uralensis

Determination of phenolic composition and antioxidant capacity of native red wines by high performance liquid chromatography and spectrophotometric methods

“…They are increasingly being recognised for their nutritional value, since they may help reduce the risk of chronic disease and in general, have a positive effect on health (Tucker & Robards, 2008). They act as antioxidants, scavenge free radicals that induce vascular relaxation (del Alamo, Casado, Hernandez, & Jimenez, 2004) and they have been reported to have anti-inflammatory (Terra et al, 2007), anti-carcinogenic (Nichenametla, Taruscio, Barney, & Exon, 2006), anti-atherogenic, anti-thrombotic (Erlund et al, 2008), antimutagenic (Ferguson, 2001), antiviral (Kwon et al, 2010) and antibacterial (Tosi, Re, Ortega, & Cazzoli, 2007) properties.…”

Effect of Grape Seed Extract on Human Norovirus GII.4 and Murine Norovirus 1 in Viral Suspensions, on Stainless Steel Discs, and in Lettuce Wash Water

“…However, most of the time, antimicrobial activity is solely tested against bacteria, yeast, and molds. In contrast, reports on the antiviral effects of plant extracts are rather limited (16,26,31).…”

Structures of Two New Flavonoids and Effects of Licorice Phenolics on Vancomycin-Resistant Enterococcus Species

“…Those fractions were purified by preparative TLC on silica gel or by preparative HPLC to give isolicoflavonol (7) [22], isoglycycoumarin (8) [23], licoarylcoumarin (9) [24], formononetin (10) [25], and 6"-O-acetylliquiritin (11) [26]. On the other hand, the remaining part of the ethyl acetate fraction was directly subjected to column chromatography on ODS-gel, and fractions from the column were further purified by column chromatography on MCI-gel CHP-20P, and by preparative HPLC or preparative TLC, to give liquiritin (12) [27], p-hydroxybenzoic acid (13), semilicoisoflavone B (14) [28], glycyrol (15) [29], glycyrin (16) [29], gancaonin I (17) [30], isoglycyrol (18) [31], liquiritigenin (19) [27], gancaonin G (20) [36], glicoricone (25) [37], glycycoumarin (26) [38], licocoumarone (27) [29], licoricone (28) [39], glyasperin D (29) [40], isoangustone A (30) [41], and two additional compounds temporarily named compounds A (31), and B (32). Since several phenolics from licorice display potent antibacterial effects against methicillin-resistant Staphylococcus aureus (MRSA), and also show suppressing effects on the oxacillin resistance of MRSA, as we have reported previously [11], we have also investigated the effect of these licorice phenolics on VRE.…”
