(S)-Linalyl, 2-Phenylethyl, and Benzyl Disaccharide Glycosides Isolated as Aroma Precursors from Oolong Tea Leaves
1994
Three glycosides, 6-O-β-d-xylopyranosyl-β-d-glucopyranosides (β-primeverosides) of the aroma constituents, linalool, 2-phenylethanol, and benzyl alcohol, were isolated as aroma precursors from the tea leaves (Camellia sinensis var. sinensis cv. Shuixian and Maoxie, cultivars for oolong tea). The isolation was guided by acid or enzymatic hydrolysis, and subsequent GC and GC-MS analyses. The linalyl glycoside is the first example of naturally occurring (S)-linalyl β-primeveroside.
