对两种金花茶的生化成分进行了对比分析，结果表明普通金花茶的含水量、水浸出物、总黄酮、水溶性糖的含量分别为6.18%、30.16%、0.214%、10.09%，而显脉金花茶的对应含量则为10.06%、18.97%、0.445%、3.69%。普通金花茶的游离氨基酸为6.5014 mg/g，显脉金花茶游离氨基酸的含量为1.2575 mg/g。二者茶多酚的含量均较少，总体上是显脉金花茶多于普通金花茶。在香气成分上，普通金花茶鉴定出45种，而显脉金花茶则只有26种。由上面的对比可以看出普通金花茶与显脉金花茶的差异性还是很大，普通金花茶的开发价值更大。

Biochemical components in the leave of two Camellia chrysantha (Hu) Tuyama species were analyzed. The results showed that, the contents of water, water extract, total flavonoids and soluble sugar of Camellia nitidissima were 6.18%, 30.16%, 0.214% and 10.09%, respectively. For Camellia euphlebia the contents of those components were 10.06%, 18.97%, 0.445% and 3.69%, respectively. The content of total free amino acid in Camellia nitidissima was 6.5643 mg/g. The content of total free amino acid in Camellia euphlebia was 1.2720 mg/g. For the content of tea polyphenols, both of the samples were little. In general, Camellia nitidissima was more than Camellia euphlebia. As for aroma compositions, Camellia nitidissima was identified for 45 kinds, Camellia euphlebia was identified for 26 kinds. Camellia nitidissima was different from Camellia euphlebia in the contents of biochemical components. The development of Camellia nitidissima is more valuable.
