Table 1.
Phenolic compounds composition of cactus seed oil from different region of Morocco expressed in mg/kg and shown as mean ± SD (n = 3). Statistical difference was determined by one-way ANOVA followed by Tukey post-hoc test. Different letters in the same line comparing the regions represent statistically significant results at 95% confidence interval.
