Investigation of the distribution and season regularity of resveratrol in Vitis amurensis via HPLC–DAD–MS/MS.

Highlights: [•] Resveratrol contents were detected via HPLC–DAD–MS/MS. [•] The method was applied and validated for resveratrol from Vitis amurensis. [•] LOD for resveratrol was 0.009μg/ml and LOQ was 0.027μg/ml, respectively. [•] The resveratrol distribution trend in the entire V. amurensis plant is firstly reported. [ABSTRACT FROM AUTHOR]
