Abstract:
The ascorbic acid contents of 48 kinds of wild vegetables, 8 kinds of tree leaves and 6 other plant materials were determined by the 2:0 dichloro-phenol indophenol titration method. Values higher than 100 mg% were Astragalus sinicus L., Lathyrus maritimus Bigel. and sixteen others. Values between 50-100 mg% were Matricaria chamomilla L., Lepidium virginicum L. and sixteen others. In general, wild vegetables and certain tree leaves contain more vitamin C than the usual cultivated plants.Vegetables (wild) and tree leaves collected in July appeared to contain less ascorbic acid than those collected during January to June. Vegetables (wild) grown in sunny places contained more ascorbic acid than those grown in shady ground. Most wild vegetables and tree leaves taken at different times of the year showed great variation (2-3 times) in ascorbic acid contents. Only a few showed little variation.
