Values in parentheses are per cent of total polyphenols measured by LC-MS. Data are expressed in mg/100 g almonds as mean ± SD, n = 9 (Butte, Carmel, Nonpareil) and n = 3 (Sonora, Mission, Monterey, Fritz). Values bearing different letters differ among columns, tested by ANOVA and Tukey's HSD, P ≤ 0.05.
