Abstract
Distribution of l-ascorbic acid in leaves of Italian officinal plants. Quantitative and taxonomic aspects.—Fresh samples of 119 Italian officinal plants belonging to 41 families of Angiosperme were assayed for l-ascorbic acid content.
Estimation of data as reported by Seybold and Mehner indicates that relatively high contents are generally found among the Rosaceae, while low amounts are usual within Asteraceae. However, species with leaves rich in l-ascorbic acid may be found at widely different places of the taxonomic system.
Since the vitamin C is widespread in the plant kingdom it has been recommended the indication of the exact amount of vitamin C when a plant is reported as antiscorbutic.
Finally the knowledge of families whose species more frequently show large amounts of vitamin C may facilitate researches of edible wild plants with high content of vitamin C.
