NOVEL MONOTERPENE DISACCHARIDE GLYCOSIDES OF VITIS VINIFERA GRAPES AND WINES

β-Rutinosides (6-O-α-L-rhamnopyranosyl-β-D-glucopyranosides) and 6-O-α-L-arabinofuranosyl-β-D-glucopyranosides of geraniol, nerol and linalol have been isolated and characterized in Muscat of Alexandria grapes and wine.These monoterpene disaccharide glycosides, which are precursors of linalol oxidation state monoterpenes of the grape, are also present in another non-muscat Vitis vinifera var.Rhine Riesling.Key Word Index - Vitis vinifera; Muscat of Alexandria; Rhine Riesling; grapes; wine; monoterpene glycoside; structure; β-rutinoside; 6-O-α-L-arabinofuranosyl-β-D-glucopyranosides; disaccharide.

Synthesis and antiglycation activity of kaempferol-3-o- rutinoside(Nicotiflorin)

Kaempferol-3-O-α-L-rhamanopyranosyl-(1″-6″) -β-D-glucopyranoside (1) (Nicotiflorin or kaempferol-3-Orutinoside), isolated from the aerial parts of Osyris wightiana Wall. ex Wight, has exhibited a potent antiglycation activity in vitro. A short and efficient route to kaempferol-3-O-rutinoside (1) is also described in this paper. To study the Structure-Activity Relationship (SAR), few other derivatives of kaempferol were also evaluated for their antiglycation activity. Moreover the cytotoxicity analysis was also performed for these compounds prepared and SAR studies showed that sugar derivatives of kaempferol possess a promising antiglycation activity.

SYNTHESIS OF 1,2-trans-DISACCHARIDES via SUGAR THIO-ORTHOESTERS

The reaction of sugar 1,2-thio-orthoesters in the D-gluco, D-galacto, D-manno, and L-rhamno series with primary and secondary trityl ethers of monosaccharides, in the presence of triphenylmethylium perchlorate as catalyst, affords, stereospecifically, derivatives of 1,2-trans-disaccharides in good yields. 4-Trityl ethers of benzyl 2-acetamido-3,6-di-O-acetyl-2-deoxy-α-D-glucopyranoside and methyl 2,3,6-tri-O-benzoyl-α-D-galactopyranoside exhibit low reactivity in glycosylation by thio-ortho-esters.A reaction scheme for the glycosylation is discussed.
