摘要:
为选出品质较好,特别是左旋多巴产量较高的蚕豆以及最适的芽苗菜采收期,选择‘临蚕二号’、‘启豆一号’、‘海门大青皮’、‘北斗七星’、‘黑蚕豆’和‘红香蕉’共6个供试品种进行试验,设置4个采收期(萌发后第3、6、9和12天),分别对芽苗菜的生长指标和营养指标进行测定和分析。结果显示:随着采收期的延长,蚕豆芽苗菜苗高和可食鲜重均增加,于第12天采收时达最大值,此时左旋多巴产量也达到最高。‘黑蚕豆’在第12天采收时可食鲜重最大,可溶性蛋白、游离氨基酸和总黄酮含量均表现最佳,且左旋多巴产量最高,为1 392.48 mg/10株,‘海门大青皮’和‘启豆一号’分别位居第二和第三位。综合来看,适宜左旋多巴提取的最佳蚕豆品种为‘黑蚕豆’,最适采收期为第12天。本研究为后续蚕豆芽苗菜药用成分的规模生产提供了一定的理论依据。

Abstract:
In order to screen for broad bean variety with better quality, especially with high L-dopa yield, six broad bean varieties, Lincan No. 2, Qidou No. 1, Haimen Daqingpi, BeiDouQiXing, Black Broad Bean and HongXiangJiao were tested for quality comparison. Four harvesting periods(3rd, 6th, 9th and 12th days)were set to investigate the most suitable harvesting period for sprouts. The growth index and nutrition index of sprout vegetables were measured and analyzed. The results showed that with the extension of the harvesting period, the height and edible fresh weight of broad bean sprouts increased, reaching the maximum at the 12th day of harvest, and the yield of L-dopa also reached the highest at this time. The edible fresh weight of Black Broad Bean was the largest when harvested on the 12th day, the content of soluble protein, free amino acid and total flavonoids were the best, and the yield of L-dopa was the highest, which was 1 392. 48 mg/10 plants. Haimen Daqingpi and Qidou No. 1 ranked second and third respectively. Taken together, the best broad bean variety suitable for L-dopa extraction is Black Broad Bean, and the optimal harvest period is the 12th day. This study provides a theoretical basis for the subsequent mass production of medicinal ingredients in broad bean sprouts.
