Abstract Berries of six Vitis davidii Foex (spine grape) cultivars (‘Baiputao’, ‘Gaoshan 1’, ‘Gaoshan 2’, ‘Seputao’, ‘Miputao’, and ‘Tianputao’) were harvested from a commercial vineyard in Hunan Province in China. Free and bound volatile compounds and fatty acids were analyzed by GC–MS, and amino acids were analyzed by HPLC. ‘Tianputao’ and ‘Miputao’ were characterized by relatively higher concentrations of aromatic amino acids and lower concentrations of branched-chain amino acids. The major free volatile compounds of spine grapes were hexanal, (E)2-hexenal, 1-hexanol, (E)-2-hexenol, (E)-b-damascenone, and benzeneacetaldehyde. The major glycosidically bound volatile compounds identified were 1-hexanol, menthol, nerol, 1-butanol, 3-methyl-3-butenol, benzenemethanol, bphenylethanol, eugenol, and guaiacol. (E)-b-damascenone, benzeneacetaldehyde, guaiacol, and eugenol had odor activity values (OAVs) [ 1 in all cultivar grapes. Partial
least squares discriminant analysis (PLS-DA) revealed ‘Tianputao’ to be distinct from the other cultivars due to its relatively higher concentrations of major terpenoids, norisoprenoids, higher alcohols, and aromatic amino acids.

Introduction The spine grape (Vitis davidii Foex) is one of the major wild grape species in Southern China and is characterized by spines covering its shoots. Spine grapes are strongly resistant to heat, humidity, and diseases, such as spot anthracnose (Meng et al., 2012a). It is widely distributed in Southern China, especially in the Hunan, Jiangxi, and Fujian provinces. In recent years, development of the spine grape industry in the Hunan Province has been rapid,
