- 摘要:
- 为促进云南金花茶产品开发,以云南金花茶的花、嫩叶、老叶为试材,采用离子体发射光谱仪、碳氢分析仪和分光光度法等对7种常量元素、5种微量元素,以及3种生理活性成分进行了测定。结果表明:花和嫩叶中的常量元素以钾元素含量居多,而老叶中则以钙元素含量居多,且在常量元素中钾元素含量均高于钠元素,呈现出高钾低钠的特点。微量元素中,均以硅元素含量最高,铜元素含量最低。此外,云南金花茶的3种生理活性成分含量,均呈现出茶多酚>粗多糖>总黄酮的规律。
- Abstract:
- In order to promote the product development of C.fascicularis,taking flowers,tender leaves,and old leaves of Camellia fascicularis as the tested materials,the contents of 7 major elements,5 trace elements and 3 kinds of physiological active ingredients were determined by plasma atomic emission spectrometry,carbon-hydrogen analyzer and spectrophotometer.The results showed that among the 7 major elements,K content was the highest in the flowers and tender leaves,and Ca content was the highest in the old leaves.Among the 7 major elements,the content of K was higher than that of Na,which showed the characteristics of high potassium and low sodium.In the 5 trace elements ,the content of Si was the highest,and Cu content was the lowest.In addition,the three kinds of physiological active ingredients contents in the flowers,tender leaves and old leaves were tea polyphenols > crude polysaccharide>total flavonoids.
