摘要: 为探究陕茶1号茶树花生物学特征和不同花期的内含成分,以陕茶1号的茶树花为原料,龙井43为对照,观测盛开期茶树花的生物学特征和百花重,分析不同花期茶树花内含成分含量差异。结果表明,陕茶1号茶树花花冠直径2.2~3.5 cm,百花重在花蕾期、露白期、盛开期均低于龙井43,且随着茶树花开放程度的增大,水浸出物、可溶性糖含量呈递增趋势,茶多酚、咖啡碱含量呈递减趋势,游离氨基酸含量呈先减后增趋势,总黄酮含量呈先增后减趋势。陕茶1号水浸出物含量53.63%~68.77%、茶多酚含量9.26%~13.79%、游离氨基酸含量1.67%~2.10%、咖啡碱含量0.43%~0.83%、可溶性糖含量11.96%~31.28%、黄酮含量27.65~38.45 mg/g。陕茶1号属于中小型花、花蕊较多的品种,在不同花期茶多酚含量高于龙井43,可溶性糖、咖啡碱、游离氨基酸、总黄酮低于龙井43。

Abstract: To clarify the biological characteristics and internal components of the different stage of Camellia sinensis ‘ShanCha 1’, the tea flowers of Camellia sinensis ‘Longjing 43’ (control group) and Camellia sinensis ‘ShanCha 1’ were used as raw materials to determine and analyze the differences in the content of components in tea flowers at different flowering stages by observing the biological characteristics and a one-hundred flowers weight of tea flowers at full-bloom stage. The crown diameter of Camellia sinensis ‘ShanCha 1’ tea flowers was 2.2-3.5 cm, and the weight of 100 flowers was less than that of Longjing 43 in the flower bud, the white bud and the full blooming stage. With the increase of the opening degree of tea flowers, the content of water extract and soluble sugar showed an increasing trend, the content of tea polyphenols and caffeine showed a decreasing trend, the content of free amino acids showed a trend of decreasing first and then increasing, and the content of total flavonoids showed a trend of increasing first and then decreasing. The water extract of Camellia sinensis ‘ShanCha 1’ was 53.63%-68.77%, tea polyphenols were 9.26%-13.79%, free amino acid was 1.67%-2.10%, caffeine was 0.43%-0.83%, soluble sugar was 11.96%-31.28%, and the total amount of flavonoids was 27.65-38.45 mg/g. Camellia sinensis ‘ShanCha 1’ was a tea flower variety with small and medium flowers and more stamens. The content of tea polyphenols was significantly higher than that of Longjing 43 at different flowering stages, and soluble sugar, caffeine, free amino acids and total flavonoids were lower than those of Longjing 43.
