Fig. 4From: Induced extracellular production of stilbenes in grapevine cell culture medium by elicitation with methyl jasmonate and steviosideExtracellular production of trans-resveratrol and δ-viniferin in the grapevine cell culture medium. a, b Extracellular production of trans-resveratrol and δ-viniferin in grapevine cell culture medium after treatment with different solubilizers. Cells were pre-cultured for 7 days and harvested 5 days after co-application of 100 µM MeJA and 50 mM MeβCD or 50 mM STE as a solubilizer. c Time-course of δ-viniferin production in grapevine cell culture medium after co-treatment with MeJA and STE. d, e Water solubility enhancement of trans-resveratrol and δ-viniferin in STE solution. The solubility of trans-resveratrol (blue) and δ-viniferin (red) in aqueous solution with increasing STE concentrations (%, w/v) was determined. (Insert) Images of trans-resveratrol (RES) and δ-viniferin (VIN) dispersion with 0.5% STE concentration (w/v). The culture medium of the elicited cells was extracted with ethyl acetate and analyzed by HPLCBack to article page
