摘要： 为研究贵州大树茶(Camellia thea L.)儿茶素组分含量、品质及酯型儿茶素比例等问题，以安顺、六盘水、兴义、黔西南大树茶资源和‘福鼎大白茶’为试验材料，采用平均数差异性分析对各资源的6项儿茶素组分进行了研究。结果表明，安顺、六盘水、兴义、黔西南大树茶资源及‘福鼎大白茶’的酯型儿茶素比例(EGCG、ECG、GCG)依次为81.55%、41.10%、83.13%、77.03%、82.85%，儿茶素品质指数依次为5.39、19.79、7.84、5.25、6.65。当欧式距离阀值为0.9~3.2时，兴义大树茶资源与‘福鼎大白茶’较为相似，安顺与黔西南的大树茶资源较为相似。

Abstract: In view the catechin components determination, quality and ester catching proportion of the Sect. Thea tea trees in southwestern Guizhou Province, we used Sect. Thea tea trees natural resources in Anshun City, Liupanshui City, Xingyi City, Qianxinan State of Guizhou Province and‘Fudingdabaicha’tea trees as the test material and took the average differences analytic methods to analysis the 6 catechin components determination (EGC, DL-EC, EGCG, GCG, ECG). The results showed that the esterncatechines of Sect. Thea tea trees in Anshun City, Liupanshui City, Xingyi City, Qianxinan state were 81.55% , 41.10% , 83.13% , 77.03% , 82.85% , and the quality index were 5.39, 19.79, 7.84, 5.25, 6.65, respectively. Cluster analysis results showed that Sect. Thea tea tree in Xingyi City was similar to‘Fudingdabaicha’tea trees, while Sect. Thea tea tree in Anshun City was similar to Sect. Thea tea trees in Qianxinan state when the threshold value of Euclid distance were 0.9 to 3.2.
