* Positive reference standard; Values expressed are mean ± standard deviation (n = 3). For different extracts with the same concentration, means in the same column with different letters (a-e) were significantly different (p < 0.05, ANOVA). For the same extract or standard with different concentrations, means in the same row with different letters (v-z) were significantly different (p < 0.05, ANOVA).
