Abstract:
In order to investigate the non-anthocyanin of five different red wine grape varieties in the northern foothills of Tianshan accumulation characteristics, five red wine grape varieties from Wujiaqu production area were selected to detect the content and composition of flavonol and flavan-3-ol during growth and development. Three major categories of flavonols were quercetin, kaempferol and myricetin. The results showed that the content of quercetin, kaempferol and myricetin in 'Cabernet Sauvignon' reached the maximum at 12 weeks after flowering, which were 0.122 mg/g, 0.015 mg/g, 0.065 mg/g, respectively. At 12 weeks after flowering, the content of quercetin substance in 'Cabernet Franc' reached a maximum of 0.500 mg/g. At 16 weeks, the contents of kaempferol and myricetin in 'Cabernet Franc' reached a maximum of 0.092 mg/g, 0.068 mg/g, respectively. The content of kaempferol of 'Syrah' reached a maximum of 0.043 mg/g at 14 weeks after flowering, but the content of myricetin substance in 'Syrah' reached a maximum of 0.042 mg/g at 16 weeks. At 16 weeks, the contents of myricetin and the kaempferol in 'Petit Verdot' reached a maximum of 0.050 mg/g and 0.035 mg/g, respectively. At 12 weeks, the content of kaempferol in 'Marselan' reached a maximum of 0.013 mg/g, and at 14 weeks, the content of myricetin in 'Marselan' reached a maximum of 0.077 mg/g. Principal component analysis of five varieties of flavonol and flavan-3-ol showed that the relative content of flavan-3-ols in 'Syrah', kaempferol in 'Petit Verdot', quercetin in 'Cabernet Sauvignon' and 'Marselan' were relatively high. The accumulation characteristics of the five varieties in the production area were different, which directly reflected the performance of the varieties in the production area. It will be helpful to grape cultivation and brewing in the northern foothills of Tianshan.
