Quantitative estimation of stilbenes in grapevine plants by HPLC-DAD. Grapevine plants (cv. Chardonnay) were treated with 30 mM thiamine (solid bars) or water (white bars) and leaves were collected at different time intervals post-treatment (1, 2, 3, and 4 dpt) for methanolic extraction of stilbenes. Data are the mean of 3 independent experiments. (A) Trans-piceide, (B) Cis-piceide, (C) Trans-resveratrol, (D) Trans-ϵ-viniferin, (E)Trans-δ-viniferin and (F) Trans-pterostilbene.
