摘要: 大叶苦丁茶(Ilex latifolia Thunb.)含有丰富的咖啡酰奎宁酸。在本研究中,运用胶束电动毛细管色谱法,测定了在不同发育时期的大叶苦丁茶不同器官中的咖啡酰奎宁酸含量。大叶苦丁茶的不同器官在不同发育时期的咖啡酰奎宁酸含量有着显著的变化。在叶片中,10天叶龄的叶的咖啡酰奎宁酸含量是19.78 g/100 g,而当叶龄达到12月时,其中的咖啡酰奎宁酸含量已经降为1.41 g/100 g。随着发育时间的增长,雌花、雄花中的含量变化也有类似的变化。雌花(果)和雄花在发育期为10天时的咖啡酰奎宁酸含量高:分别20.29 g/100 g和18.06 g/100 g,随后在雌花发育成的7个月果实中下降到0.16 g/100 g,而在40天期接近脱落的雄花中其含量降为10.36 g/100 g。大叶苦丁茶的器官中,除了嫩叶,雄花由于高含量的咖啡酰奎宁酸和较多的生物量,也是一种好的咖啡酰奎宁酸来源材料。本文首次报道了大叶苦丁茶的花中含有大量的咖啡酰奎宁酸。MEKC方法也是首次被用于苦丁茶中的咖啡酰奎宁酸类成分的测定,使用这种方法,大叶苦丁茶中的6种咖啡酰奎宁酸成分在40分钟内完全分离。相较于以前文献中报道的高效液相色谱法,本文为苦丁茶中的咖啡酰奎宁酸的质量控制提供了一种新的检测方法。

Abstract: DAYE Kudingcha is rich in caffeoylquinic acid derivatives(CQAs). CQAs in DAYE Kudingcha organs in different developing stages were determined by micellar electrokinetic chromatography(MEKC). The composition of CQAs variated greatly in tissues at differently developing stages. The content of CQAs was 19.78 g/100 g in leaves at the age of 10 days, and then decreased to 1.41 g/100 g at 12 months. A similar predisposition was observed in female and male flowers with the increasing age. Female flowers(fruits) and male flowers at the age of 10 days have a high content of CQAs:20.29 g/100 g and 18.06 g/100 g, respectively, which subsequently decreased to 0.16 g/100 g in 7-month mature fruits, 10.36 g/100 g in 40 day falling male flowers. The male flowers, as well as the young leaves, might be a good CQAs' raw material, due to a large amount of CQAs and biomass of the male flowers in the Kudingcha species. This is the first report describing the contents of CQAs in the flowers of Kudingcha. MEKC method was also used for the first time in the determination of CQAs in Kudingcha. Compared to the HPLC method described previously, the MEKC might be an alternative for the quality control of CQAs in Kudingcha.
