Primula officinalis

Two glucosides have been separated from the roots of Primula officinalis by Goris, Mascr6, and Vischniac, which have been termed primeverin and primulaverin, and which are both hydrolysed, yielding the two constituents of the essential oil. 

Free sugar in carob fruits, glycoside of Primula officinalis... 

Occurrence and preparation. Begbie and Richtmyer have shown that the dried root of the primose (Primula officinalis Jacq.) contains the heptose 50 among a number of other sugars. It was purified by column chromatography from aqueous extracts of the root.256... 

Occurrence and preparation. D-aZZro-3-Heptulose (coriose) is the first clearly characterized 3-heptulose found in a natural product. This 3-heptulose was obtained from chromatographed extracts of the roots of Primula officinalis Jacq256 (see under D-gZycero-D-gZwco-heptose), and it has also been isolated from the leaves... 

Occurrence and preparation. In the first report of its occurrence,248 D-glycero-L-galacto-octulose (63) was obtained from the pulp of ripe avocados (Calavo, Hass variety) by extraction and chromatography (see under D-g/ycero-D-ga/acto-heptose). The octulose was also isolated from the dried roots of Primula officinalis Jacq.

Oleanene-3, 16o,28-triol Primulagenin A C30H50O3 458.73 465-95-2 Primula officinalis... 

C oHjsO,. Mr 476.43, mp. 203-204°C, [a]g -71.5° (H2O). P. is the 2-0-glycoside of methyl 2-hydroxy-4-methoxybenzoate with primeverose. P. occurs together with primulaverin (2-O-glycoside of methyl 2-hydroxy-5-methoxybenzoate with primeverose, C20H28O13, Mr 476.43) in the roots of Primula officinalis and other primrose species. 

Found in roots of Primula officinalis. Cryst. (MeOH). 

Found combined in baker s yeast, in the cell wall lipopolysaccharides of enterobacteria and the roots of Primula officinalis. A homopolymer occurs in the lipopolysaccharide of Helicobacter pylori strain D4. 

Constit. of Coriaria japonica, Coriaria nepalensis, Coriaria ruscifolia, Coriaria thymifolia and Coriaria intermedia. Also from roots of Primula officinalis. 

Isol. from dried roots of Primula officinalis. Also from fruits of Persea americana... 

P-Pyranose form predominates in aq. soln. Present in ripe avocados, dried roots of Primula officinalis and several Crassulaceae. 

Present in avocado (Persea gratissima), Sedum spp., alfalfa (Medicago sativa), roots of Primula officinalis, poppy (Papaver somniferum) etc. 

Constit. of a number of naturally occurring phenolic glycosides such as Prime-verin and Primulaverin from Primula officinalis. 

D-Xylosyl-D-glucose (primeverose). M.p. 209°C. [o ]d +23° —> —3.4° (water) obtained by partial hydrolysis of a glycoside from Primula officinalis 132) from madder root 133). (See Ruberythric acid.) The synthesis has been accomplished by coupling 2,3,4-tri-O-acetyl-a-D-xylosyl bromide with 1,2,3,4-tetra-O-acetyl-iS-D-glucose 134). 

The fresh roots of Primula officinalis, when strongly bruised, develop more or less rapidly, but always very distinctly, a marked odour. This odour recalls at first that of anise, but that of methyl or amyl salicylate finally predominates.
