黄酮类物质是芹菜最重要的次生代谢产物。该研究通过反相高效液相色谱测定了44份中国芹菜种质、美国西芹‘文图拉’和欧洲西芹‘皇后’叶片和叶柄中的芹菜素和毛地黄黄酮的浓度。结果表明:这46份芹菜种质叶片和叶柄中的芹菜素和毛地黄黄酮含量存在显著差异,叶片芹菜素含量、叶片毛地黄黄酮含量、叶片黄酮含量、叶柄芹菜素含量、叶柄毛地黄黄酮含量和叶柄黄酮含量的变异系数分别为30%,10%,30%,20%,30%和20%。叶片和叶柄中的黄酮含量没有相关性。叶片中芹菜素浓度是毛地黄黄酮浓度的18~50倍,叶柄中芹菜素浓度是毛地黄黄酮浓度的19-40倍。大部分中国芹菜种质的黄酮浓度高于西芹‘文图拉’和‘皇后’。分布在中国长江以南地区芹菜种质的黄酮含量高于北部地区芹菜种质。综上所述,叶柄是主要食用部位,因此叶柄具有高芹菜素含量的中国芹菜种质可应用于芹菜的育种,叶片具有高芹菜素含量的中国芹菜种质可应用于生产芹菜素产品。
Flavonoids are the most important secondary metabolites of celery. In this study, the concentrations of apigenin and lutein in 44 Chinese celery germplasms, American celery ’Ventura’ and ’Celestial’ queen’s leaf and petiole in European celery were determined by RP-HPLC. The results showed that the contents of apigenin and luteolin in the leaves and petioles of the 46 celery cultivars were significantly different. The content of apigenin in leaves, the content of flavonoids in leaves, the content of flavonoids in leaves, the content of apigenin in leaves, And the coefficient of variation (CV) of petiole flavonoids were 30%, 10%, 30%, 20%, 30% and 20% respectively. There is no correlation between flavonoid content in leaves and petioles. The concentration of apigenin in leaves is 18-50 times higher than that of luteolin, and the concentration of apigenin in petioles is 19-40 times of the concentration of luteolin. Most Chinese celery germplasm flavonoids concentrations higher than Celery ’Ventura’ and ’Queen’. The content of flavonoids in celery germplasm distributed in the area south of the Yangtze River in China is higher than that in northern area. In summary, the petiole is the main edible parts, so Chinese celery germplasm with high apigenin content can be used for celery breeding. Chinese celery germplasm with high apigenin content can be applied to the production of apigenin.
