Concentration of (a) pallidol and trans-resveratrol and (b) ε-viniferin and δ-viniferin in Vitis labrusca cell suspension grown in shake flasks and elicited with methyl jasmonate 0.7 mM, 5.6 g DW cells/L and no sucrose supplementation (white bars, extracellular concentration; grey bars, intracellular concentration). Results are the mean of duplicate flasks and expressed in milligrams per liter (mg/L) of whole medium (extracellular medium and cells). The error bars represent the standard deviation.
