-"The sensory quality ranking of Japanese green tea (Sen-cha) was evaluated and predicted using volatile profiling and multivariate data analyses... The major volatile compounds identified from chromatographic profiles obtained both non-polar and polar columns were coumarin, dihydroactinidiolide,​ linalool oxides, geraniol, trans-geranylacetone,​ indole, 6-chloroindole,​ β-ionone, 5,​6-epoxy-β-ionone,​ cis-jasmone,​ linalool, methyl jasmonate, trans-nerolidol,​ 1-octanol, 2-pentanol, phenylethyl alcohol, and phytol... By examining the loadings of PLS–DA, the significant variables contributing to the classification of the high and low quality green tea sample were revealed. They implied that the higher quality green tea samples contained a relatively higher concentration of phytol, caffeine, cis-jasmone,​ linalool oxide (trans-pyranoid),​ 6-chloroindole,​ trans-geranylacetone,​ methyl jasmonate, and some unknown compounds, compared to the lower quality ones. Whereas, geraniol, linalool, dihydroactinidiolide,​ linalool oxides (cis- and trans-furanoid),​ and coumarin were found in the lower concentration in the higher grade green tea samples."​ \\+"The sensory quality ranking of Japanese green tea (Sen-cha) was evaluated and predicted using volatile profiling and multivariate data analyses...
