“…In the study in which the effects of factors on L-DOPA contents in faba bean were examined, Kai-Bin et al determined the average L-DOPA content in bean flowers as 4.48% [41]. In the same study, it has been reported that L-DOPA contents may vary according to flower colors, L-DOPA content decreases proportional to the darkening of the color, and the flower bud form contains more L-DOPA compared to the open flower form.…”

Honey is nectar collected from plants and produced by honeybees Apis mellifera. It has variable sensory and bioochemical properties due to climate and environmental conditions as well as the different origins of the plants in which it is harvested. Studies have shown that the antioxidant potential of honey varies greatly with the source of flowers. Vicia faba L. also known in Turkey as `bakla,` is a genus of the family Fabaceae that is widely grown in Asia. It is abundant in L-DOPA, a therapeutic agent used in Parkinson`s disease diagnosis. In this study, a sample of honey has been obtained from a monofloral source in the greenhouse environment where only vicia faba l. was found. The biochemical properties and antioxidant activities of this honey sample were studied. Vicia faba L. flowers grown in greenhouse conditions and pollen and honey produced by bees fed from this flowers were analyzed with HPLC method. The results were quite surprising. L-DOPA content is 4.23% in flowers, 0.98% in pollen and 0.076% in honey. This leads to the conclusion that Parkinson`s patients can continue treatment by using only pollen and honey produced by bees that feed on Vicia faba L. flowers. In addition, antioxidant activity of flowers, pollen and honey was analyzed by spectrophotometric methods. Parallel results were obtained with the results previously studies.

Significant quantities of 3,4-dihydroxy-L-phenylalanine (L-DOPA or levodopa) are present in the plant structures of Vicia faba, a compound utilized in the treatment of Parkinson's disease. In Mexico, the cultivation and per capita consumption of V. faba is low, suggesting that exploiting the species through its biomass could enhance the utilization of this phytogenetic resource. The objectives were: (1) to evaluate the morphological characteristics of seeds from 24 local V. faba varieties originating from production areas, and (2) to analyze the content and yield of L-DOPA in the young plants of these 24 local varieties to assess the variation of this compound. The local varieties were collected in seven growing localities in Puebla, Mexico. Seed local varieties were measured for length, width, and weight of 100 seeds to determine their size. Subsequently, the seeds were sown in the field, and plants were harvested 20 days after emergence. The plant material was processed, and L-DOPA content was quantified using UV-visible spectrophotometry, and the yield per plant was obtained. L-DOPA content and yield ranged from 127.91 - 179.52 mg g-1 DM and 223.27 - 584.21 mg plant-1, respectively. Principal component and cluster analysis identified five groups differentiated by seed morphological variables, biomass and L-DOPA. It was shown that the L-DOPA content in the plant is not influenced by the place of origin of the seed, and that seed size can be an indicator of the amount and yield of L-DOPA. The production of this bioactive compound via V. faba biomass may be considered a natural resource with commercial potential.
