11个大粒蚕豆品种蚕豆花左旋多巴资源评价

Resource Evaluationof of Levodopa in Broad Bean Flowers of 11 Large Broad Bean Varieties

摘要: 研究不同大粒蚕豆品种蚕豆花左旋多巴含量及其经济价值，为蚕豆花的利用提供参考依据。收集11个大粒蚕豆品种生产中摘除的蚕豆花，提取其左旋多巴成分，利用液相色谱法检测蚕豆花左旋多巴的含量，进一步估算其经济价值。结果表明：陵西一寸品种蚕豆花左旋多巴含量最高，达到7.57%，通蚕鲜8号品种蚕豆花左旋多巴经济价值最高，每667 m²产量达到1 893.97 g，每667 m²产值达到946.99元。

Abstract: The content and economic value of levodopa in broad bean flowers in the different varieties of large broad bean were studied to provide reference for the utilization of broad bean flowers. The broad bean flowers extracted from the production of 11 large broad bean varieties were collected to extract the components of levodopa. The content of levodopa in broad bean flowers was determined by liquid chromatography and its economic value was further estimated. The results showed that the content of levodopa in broad bean flowers of Lingxiyicun Variety was the highest (up to 7.57%), and the economic value of levodopa in broad bean flowers was the highest in the variety of Tongcanxian No.8, with the yield reaching 1 893.97 g per 667 m² and the output value reaching 946.99 yuan per 667 m².
