“…Other heat-stable conrpounds with potential antinutritional activity are L-3, 4-dihydroxyphenylanine (L-DOPA) (Mager et al 1969) and its glucoside. These are located mainly in the green pod and partly in the testa ofthe bean (Longo et al 1974 …”

“…It could be many reasons as kind of seed and soil conditions. Longo et al (1974) reported that V. faba var. minor had been the most content of L-dopa; Huang & Chen (1998) reported that if potasium nitrate and ammonium nitrate are used together L-dopa content increases and phosphate are negatively correlated with calcium but positively correlated with zinc content of soil.…”

Faba bean, reflecting all properties of legume crops such as soil improvement and benefit of human health, also contains L-dopa which can be used to cure Parkinson's disease, is a rare plant. The study was conducted in Samsun province to determine the L-dopa content of leaf, flower and pod of faba bean genotypes. Four cultivars and 18 lines were sown on November in randomized complete blocks design with 3 replications. Samples were taken from leaves at vegatative period, flowers and fresh pods at generative period of faba bean. The L-dopa content was determined by HPLC. According to the result of variance analysis, the differences among genotypes for L-dopa content of flowers and fresh pods were found significant (P<0.01). L-dopa content of leaves, flowers and fresh pods varied between 10. 88-33.41, 40.95-96.37; 4.16-52.28 mg kg -1 , respectively. L-dopa content of flowers of 20 genotypes, except a cultivar and a line, were found in same group statistically. Avarage L-dopa content of leaf, flower and pod of faba bean were 19.36, 75.87 and 25.27 mg kg -1 , respectively. The most common form of consumption of faba bean in Turkey and treatmet for Parkinson's disease in some countries is fresh pod. However this study showed that L-dopa amount in flower is higher (P<0.01) than that of leaf and pod. Results of this study revealed that L-dopa content of 7 lines were richer than that of others. If agronomic characters of 7 lines are well, their potential to become a new variety should be investigated.

“…In 1913, a Swedish pharmaceutical chemist named Guggenheim firstly isolated L-Dopa from faba bean, and found that the L-Dopa content in pod shell of faba bean was 0.25%. Rocco et al (1974) suggested that L-Dopa contents were different in different organs of faba bean, such as 0.24% in whole plant, 0.36% in leaves, 0.17% in stems and 0.35% in roots before flowering. Zheng et al (2012) studied the L-Dopa content in different parts of faba bean; the results revealed that the L-Dopa content was the highest in flowers.…”

Faba bean (Vicia faba L.) flower is rich in L-Dopa used for the treatment of Parkinson's disease. In order to utilize L-Dopa from faba bean flower more efficiently, the effects of factors on L-Dopa contents in faba bean flowers determined by HPLC were studied. Results showed that the L-Dopa contents in faba bean flowers differenced in germplasm resources, the highest L-Dopa content in faba bean flowers was 20 times higher than that of the lowest. The average contents of two years ranged from 0.53% to 10.63%, and the average was 4.48%.The darker the flower colors, the lower the L-Dopa contents in faba bean flowers. The L-Dopa contents of faba bean flowers of small seed species were lower than the medium and the large species in faba bean flowers. The L-Dopa contents of the buds were higher than open flowers. As the drying temperature increased, the L-Dopa contents reduced. That dried in 100°C was only 60% of that at 40°C.
