2.7. Statistical analysis
The means and standard deviations of moisture content, oil
extraction yield, chemical characteristics, phytochemical contents
and antioxidant activity were reported in triplicate determinations
for each sample. Statistical analysis of data was performed using
one-way analysis of variance (ANOVA). Mean comparison was
carried out using Duncan’s multiple range test (Steel & Torrie,
1980). The statistical analysis was performed by SPSS 11.0.
