    Notes: [Auszug] Fig. 1. Respiration-rate of fruits from control and malate-injected branches of apple trees In view of these results it was decided to investigate the effect of added malate on the production of carbon dioxide of whole apples. Malate (at p£L 3-8) was injected into a branch of a Bramley's ...

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] For some time now, we have been endeavouring to obtain active particles from several varieties of English apples by the general methods described in the literature for the isolation of mitochondria from plants. Briefly, the fruit was peeled, cut into cubes and extracted with 0-4 M sucrose buffered ...

    Shikimic Acid in Apple Fruits (1956)
    [s.l.] : Nature Publishing Group
    Nature 178 (1956), S. 991-992 
    Details
    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] The acid is barely detectable in the peel of unripe apples; but it increases in amount as the fruit ripens and becomes senescent. The amount of shikimic acid in pulp tissue even from senescent fruit is extremely small. It is interesting that there is also much less quinic acid in the pulp than in ...

    Carbon Dioxide Injury and the Presence of Succinic Acid in Apples (1956)

    Details
    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] In normal healthy apples we have found succinic acid only occasionally and in trace amounts in either the peel or the pulp. This does not necessarily meanthat succinate is not a normal intermediate metabolite in the fruit ; its turnover-rate may be so high as to prevent accumulation. It was ...

    Notes: [Auszug] Upwards of 100 mgm. of acid B has now been obtained from extracts of a pure strain of grass (Lolium perenne) dried at 80 C. in a current of air. This specimen had a melting point of 183-184 C. (corrected), mixed melting point with authentic shikimic acid (kindly supplied by Dr. H. O. L. Fischer) ...

    Notes: [Auszug] Paper chromatograms, prepared from certain 'acid fractions' of extracts of immature apple fruits, run in butanol - formic acid - water (40: 10: 50 v/v), and sprayed with suitable indicator solutions, gave spots for several 'unknown' acids (RF 0-24, 0-29, 0-43, 0-50, 0-67, 0-81), the largest spot ...

    Notes: [Auszug] Samples of the original materials isolated by these authors became available in this laboratory. They were therefore subjected to infra-red analysis using the potassium bromide disk method. The resulting spectrograms are shown in Kg. 1. This evidence clearly establishes the identity of the two ...

Sprayed with ninhydrin, the new acid gives a pinkish-yellow colour which shows an intense ...
