METHODS AND RESULTS:
An aqueous extract of 20 kg of the dried roots of Primula officinalis Jacq. has been deproteinized, deionized, fermented with bakers' yeast, and fractionated by chromatography on cellulose columns, Dowex 50W-X8 (Ba2+) resin columns, and sheets of filter paper. The following higher-carbon sugars were isolated: D-altro-heptulose (sedoheptulose), D-manno-heptulose, D-allo-heptulose, D-altro-3-heptulose, D-glycero-D-manno-heptose, D-glycero-D-gluco-heptose, D-glycero-D-manno-octulose, D-glycero-L-galacto-octulose, D-erythro-L-gluco-nonulose, and D-erythro-L-galacto-nonulose.
Two higher-carbon polyhydric alcohols —volemitol (D-glycero-D-manno-heptitol) and β-sedoheptitol (D-glycero-D-gluco-heptitol)—were also isolated, as well as glycerol, erythritol, xylitol, myo-inositol, D-xylose, and primeverose.
CONCLUSIONS:
Of all these substances, only volemitol had previously been isolated from P. officinalis, although primeverose was known to occur there as a constituent of the glycosides primeverin and Primulaverin. In addition, primeverose has been reduced to primeveritol (6-O-β-D-xylopyranosyl-D-glucitol), which was characterized further as the crystalline octaacetate; and the crystalline D-glycero-β-D-gluco-heptose has been converted into the new, crystalline D-glycero-β-D-gluco-heptose hexaacetate. |
