紫罗兰酮

Among 3 cultivars, B17 occupied the least green odor contents of aromatic constituents, such as 2-hexen-1-ol acetate, butanoic acid 3-hexenyl ester and butanoic acid 3-hexenyl ester, hut had the most fruity, flowery and woody odors such as β-Ionone, 1-nonanol, Acetic acid octyl ester, Methyl benzoate, Ethyl benzoate and theaspirane, which showed that B 17 was superior to the 2 other cultivars in aroma quality.
