From: Jasmonates elicit different sets of stilbenes in Vitis vinifera cv. Negramaro cell cultures
Identification and quantification of stilbenes in V. vinifera cv Negramaro. Representative chromatograms of the sample extracted from non-elicited cells (control), analyzed by RP-HPLC and detected by PDA at 306 nm (A) and by ESI-MS in negative single ion monitoring (SIM) mode at m/z 389 (B) and m/z 227 (C). RP-HPLC-PDA-ESI-MS conditions as in the Experimental section. Identification of peaks (see text): 1, trans-piceid; 2, trans-resveratrol. Representative chromatograms of the sample extracted from cells treated with OPDA, analyzed by RP-HPLC and detected by PDA at 306 nm (D) and by ESI-MS in negative single ion monitoring (SIM) mode at m/z 227 (E) and m/z 453 (F). RP-HPLC-PDA-ESI-MS conditions as in the Experimental section. Identification of peaks (see text): 2, trans-resveratrol; 3, cis-ε-viniferin; 4, trans-ε-viniferin; 5, trans-δ-viniferin.
