广东岭头单枞茶高效液相色谱指纹图谱的研究

Studies on High Performance Liquid Chromatographic Fingerprint of Lingtoudancong Oolong Tea

应用高效液相色谱方法研究了广东岭头单枞茶品种的指纹图谱,根据其高效液相色谱中的相对保留时间、相对面积、共有峰、重叠率、八强峰及其相对总面积等对色谱指纹图谱进行了分析和对比研究,建立了鉴定广东岭头单枞茶品种的色谱指纹图谱分析方法。结果表明,该方法为茶叶品种的鉴定提供了较全面的信息,为指纹图谱技术在茶叶品种和品质方面的研究提供新的途经。

The chromatographic fingerprint of Lingtoudancong Oolong tea was studied by high performance liquid chromatog- raphy (HPLC). According to the relative retention value, the relative area, common peaks, and overlap rate, the eight strong peaks and their relative total area resultants in HPLC were assayed respectivly. The chromatographic fingerprint of Lingtoudancong Oolong tea was analyzed and studied comparatively. The results showed that this method provided useful information for identification of tea variety, and a new way to study tea variety and quality by the chromatographic fingerprint was founded.
