  • Analysis of mixtures of some mono-O-methylaldoses with the common aldoses by g.l.c.-m.s. after isopropylidenation
    作者:Kai H. Aamlid、Svein Morgenlie

    日期:1983.12
    Abstract The O-isopropylidene derivatives of seven naturally occurring mono-O-methylaldoses have been characterised by g.l.c.-m.s. G.l.c. conditions have been found under which almost complete separation of the O-methyl sugars and the common aldoses as their O-isopropylidene derivatives can be achieved. This analysis procedure has been applied to the hydrolysates of three polysaccharides that contain

  • METHYLATION OF SUGAR DITHIOACETALS: IV.<scp>D</scp>-XYLOSE DIETHYL DITHIOACETAL
    作者:G. G. S. Dutton、Y. Tanaka
    DOI:10.1139/v62-291
    日期:1962.10.1

    Partial methylation of D-xylose diethyl dithioacetal in tetrahydrofuran with methyl iodide and silver oxide yielded 2-, 3-, and 5-O-methyl-D-xyloses in the ratio of 20:10:1. The poly-O-methylated components were not examined. The 2-O-methyl-D-xylose was identified as the crystalline sugar and the 3-O-methyl ether as the phenylosazone and p-bromophenylosazone. An alternative preparation of the dithioacetal in tetrahydrofuran solution is described.

    Two novel triterpenoid glycosides have been isolated from butanolic seeds extract of two varieties of Lathyrus plants, i.e. Lathyrus ratan and Lathyrus aphaca. Their structures were elucidated as 3-O-[β-D-glucuronopyranosyl-(1 → 4)-α-L-arabinopyranosyl-(1 → 2)-α-L-arabinopyranosyl]-olean–11,13(18)–dien–28-oic acid (1) and 3-O-β–D–xylopyranosyl–(1 → 2)–β-D-glcopyranosyl–(1 → 4)–[β-D-glucopyranosyl
