Resources and Analysis of Wild Vegetables Containing High Vitamin C
摘要
Abstract
Abstract; This study aimed to select suitable vegetabls from 28 varieties with high Vc content from Fujian for promotion in Jiangsu. The molybdenum blue method was used for the Vc content determination. Furthermore, in order to provide a scientific basis for future in-depth studies, the changes of Vc content in 4 vegetables were examined at different harvest times. The results indicated that the Vc contents of these 28 wild vegetables varied greatly form 6. 78 to 173. 25 mg · Hg-1. Nine vegetables with the highest Vc content were selected for further evaluation on their eating qualities. They included Chrysanthemum nankingensis H. M. , Cichorium endivia L. , Talinum trianglare (Jacy. ) Willd. , Hibiscus esculentus L. , Lycium chinen.se, Pteridium aquilinum (L. ) var. Latiusculum, Patrinia Villosaon , Taraxacum mongolicum Hand. -Mazz and Brassica oleracea L. Var. Acephato D. C. For the study on Vc content changes during the harvesting periods of 4 vegetables, the Vc content of Allium hooker Thxvaites was determinded to be 53. 52- 196. 87 mg · Hg-1, and Capsella bursa-pastoris (L. ) Medic. , Kalimeris indica (L. ) and Lactuca sativa L. Were 19. 33 - 118. 21 mg · Hg-1, 39. 89 - 120. 90 mg · hg-1 and 29. 93-117. 94 mg · Hg-1, respectively. The contents peaked at two different times. Thus, the optimal harvest time recommended for Allium hooker Thxvaites and Kalimeris indica (L. ) was from the end of April to the end of May, and for Capsella bursa-pastoris (L. ) Medic, and Lactuca sativa L. , was from the end of April to mid-May.关键词
