  1. The results are expressed as mean ± standard deviation (n = 3) of triplicate samples. Values in the same column followed by a different lowercase letter are significantly different (p < 0.05) in the same plant and part with different solvent. Different capital letter indicate significant differences (p < 0.05) between different part of the plant in the same solvent for B. buceras and same part and solvent for P. californicum (oak and mesquite)
