The Rose

Guinea-pig adrenals were stained for ascorbic acid. In the normal adrenal, staining was found in both cortex and medulla though with greatest density in the zona fasciculata. The stained scorbutic adrenal showed only a few granules.The mosses Mnium cuspidatum and Mnium affine contain ascorbic acid in appreciable amounts. Following staining, fine black granules could be seen in both species. The stain intensity of the granules roughly corresponded to their relative ascorbic acid content.Having satisfactorily established the validity of the staining solution by the above experiments the development of ascorbic acid in the rose hips of R. acicularis was followed throughout the summer. There was found to be some association between the ascorbic acid and chloroplasts. With increasing maturity there developed a gradual accumulation of fine granules in the cells of the tissue as well. These granules showed no apparent relationship to any formed elements in the cells. Staining densities roughly parallel ascorbic acid content.

Isoascorbic Acid

Guinea pigs fed with a synthetic diet or a rabbit ration were depleted of vitamin C for 17 days. The scorbutic animals were treated daily during 2 months with 40 mg D-isoascorbic acid (IAA) or 2 mg L-ascorbic acid (AA). Both isomers restored the growth of the animals and caused the disappearance of scorbutic symptoms. For 3 weeks, the two diets gave similar response, after which the animals fed with the rabbit ration grew much less. Animals given IAA ate less and had smaller weight gains than those given AA; this effect was overcome by pair-feeding. Only a small proportion of administered IAA was recovered in the organs and in the urine. The total ascorbic acid content (AA and IAA) of the IAA-treated animals was less than that of the AA-treated animals. The low AA content of the organs of the IAA-treated animals indicated that IAA had no significant sparing action on AA.
