| 摘要: |
| 探索显脉金花茶（Camellia euphlebia）和金花茶（C.nitidissima）叶片中主要活性成分的动态积累规律，为两种金花茶的合理采摘提供理论依据。以广西壮族自治区中国科学院广西植物研究所迁地保护的金花茶和显脉金花茶为试材，通过分光光度法测定叶片从抽梢至成熟过程中（11月—翌年10月）主要活性成分茶多酚、总皂苷、总黄酮和总多糖的含量动态变化规律，并利用功效系数法进行综合评价。显脉金花茶4种活性成分综合评价得分在1—2月较高，其中2月最高，茶多酚、总皂苷、总黄酮和总多糖含量分别为3.387%、8.382%、3.779%和2.786%；而金花茶的综合得分在8—10月较高，其中9月最高，4种活性成分含量分别为1.578%、3.955%、1.875%和2.389%。显脉金花茶的适宜采收期在1—2月，2月最佳；金花茶的适宜采收期在8—10月，9月最佳。 |

| Abstract: |
| The dynamic accumulation of the main active components in the leaves of Camellia nitidissima and C.euphlebia was explored to provide a theoretical basis for the reasonable picking of two kinds of Camellia.Using the C.nitidissima and C.euphlebia of Guangxi Institute of Botany,Guangxi Zhuang Autonomous Region and Chinese Academy of Sciences as test materials,Spectrophotometric method was used to determine the dynamic changes of the main active components of tea polyphenols,total saponins,total flavonoids,and total polysaccharides during the process from leaves tip to maturity (November to October of the following year),and the comprehensive evaluation was carried out by the method of efficiency coefficient.The comprehensive evaluation score of the four active components of C.euphlebia was higher from January to February,with the highest in February.The contents of tea polyphenols,total saponins,total flavonoids and total polysaccharides were 3.387%,8.382%,3.779% and 2.786%,respectively.While the comprehensive score of C.nitidissima was higher from August to October,with the highest in September.The contents of the four active components were 1.578%,3.955%,1.875% and 2.389%,respectively.The suitable harvest period of C.euphlebia was from January to February,and February was the best.The suitable harvest period of C.nitidissima was from August to October,and September was the best. |
