The determination and occurrence of a hydrojuglone glucoside in the walnut.
نویسنده
چکیده
In the preceding paper (Daglish, 1950) it was shown that juglone existed in the walnut as the glucoside of 1:4:5-trihydroxynaphthalene and not as free anor P-hydrojuglone as previously suggested (Mylius, 1885a, b). In order to determine its role in the economy ofthe plant, the occurrence ofthe glucoside was determined during the 1948 and 1949 growing periods. The methods used, together with the results, are discussed below.

use in the oxidation-reductions systems associated with increased cell metabolism. Owing to this growth, the concentration levels fall sufficiently to allow translocation of this substance from other parts of the plant to these rapidly growing centres, so that the amount actually present increases. This increase obliterates the losses that should be detected were the glucoside utilized in the f...
متن کاملThe isolation and identification of a hydrojuglone glycoside occurring in the walnut.
In a preliminary note (Daglish & Wokes, 1948) it was shown that the 'apparent vitamin C' of the walnut (Juglan8 regia) (Wokes, Organ, Duncan & Jacoby, 1943) was probably a hydrojuglone derivative. The evidence for this was based upon the findings that solutions of the substance separated by chromatography showed an ultraviolet absorption curve similar to those of reduced acetoxyjuglone and ahyd...
