Obtained Oolong tea quality is better than Huangdan with heavier appearance, strong fragrance and a better taste as well. Total water soluble, polyphenols, caffeine, catechins, EGCG and free amino acids were 43.4%, 24.1%, 2.9%, 14.6%, 5.4% and 3.0%, respectively. The total aroma oil determined in its made tea was 128.98, which was greater than Huangdan. Its main aroma components were nerolidol, benzaldehyde, jasmine jactone, α-farnesene, β-ionone and cis-jasmone.
