Quantification of aroma monoglycosides and diglycosides in fresh tea leaves. Ten glycosides were used as authentic standards to quantify endogenous glycoside in young leaves, young stems, mature leaves, and mature stems of C. sinensis: benzyl β-d-glucopyranoside (benzyl-glc), benzyl β-primeveroside (benzyl-pri), geranyl β-d-glucopyranoside (geranyl-glc), geranyl β-primeveroside (geranyl-pri), (Z)-3-hexenyl β-d-glucopyranoside (hexenyl-glu), (Z)-3-hexenyl β-primeveroside (hexenyl-pri), linalyl-glc, linalyl β-primeveroside (linalyl-pri), 2-phenylethyl β-d-glucopyranoside (2PE-glc), and 2-phenylethyl β-primeveroside (2PE-pri). Data are presented as means ± sd (n = 3). F.W., Fresh weight.
