Syntheses of R-beta-rutinosides by rutin-degrading reaction.
Rutinose and five R-beta-rutinosides were obtained by means of rutin-degrading reaction in water or aqueous alcohol (ROH, R = methyl, ethyl, propyl, isopropyl, and benzyl) with rutin-degrading enzyme as catalyst and rutin as starting material in 84-94% yields, of which methyl-beta-rutinoside, propyl-beta-rutinoside, isopropyl-beta-rutinoside, and benzyl-beta-rutinoside are firstly reported in this paper. Based on spectral analysis, the structures of all products were elucidated.
