diluted BR buffer pH 7 (30:70 for grains and hulls and 20:80 for
leaves) with spectrophotometric detection at 306 nm and electro-
chemical detection at CPE at +1.2 V. The content of trans-resveratrol
was 3.43–3.50 mg kgꢁ1 of grains of tartary buckwheat, 0.98–
1.68 mg kgꢁ1 of grains of common buckwheat, 0.66–0.21 mg kgꢁ1
of hulls of common buckwheat, 0.19–0.20 mg kgꢁ1 of leaves of tar-
tary buckwheat and 1.81–1.82 mg kgꢁ1 of leaves of common buck-
wheat for both detection methods. Electrochemical detection on
carbon paste electrode for trans-resveratrol gives comparable limits
of detection as the UV/VIS detection for cis-resveratrol is electro-
chemical detection more sensitive than UV/VIS detection which en-
ables fast and sensitive detection of light induced changes in
resveratrol samples or analysis of samples containing both isomers.
