2.5. Chemical analysis
Seeds were carefully cleaned then ground to pass
through a 0.4mm screen, for proximate analysis, on a
dry weight basis. AOAC (1975) methods were followed
in the determination of moisture (7.003), petroleum ether
extracts (7.048), crude ®bre (7.6), ash (14), and crude
protein (7.2). Carbohydrate was calculated by dierence.
2.6. Statistical analysis
Each sample was analyzed in triplicate and the ®gures
were then averaged. Data were assessed by analysis of
variance (ANOVA). The Duncan multiple range test
was used to separate means. Signi®cance was accepted
at p0.05.
