Fig. 6From: Development of an efficient glucosinolate extraction methodExtraction of glucosinolates (≥1 µmol/g) in plant tissues across the three extraction methods. Glucosinolate concentrations from the cold methanol and boiling water extraction methods are normalised to the glucosinolate concentrations obtained from the ISO9167-1 (75 °C methanol) method (n = 4–12). Error bars represent standard error. Asterisks represent a significant effect of extraction method on glucosinolate concentration (repeat measure ANOVA, p < 0.05)Back to article page
