Ground wheat straw autoclaved and non-autoclaved (l0g) was treated with 6, 8 and 10% sodium hydroxide of 1:10, 1:15 and1:20 mixing ratio for 1, 2 and 3hrs as reaction time. Results revealed a maximum value (18.79 %) of xylose were found in hydrolysate when autoclaved wheat straw was treated with 8% NaOH for 2hrs , whereas the lowest value was (13.52) % when the non autoclaved wheat straw ( 6% sodium hydroxide concentration , 1h reaction time and 1:10 solid: liquid ) used. Also, results indicated that the highest level of furfural (0.34) % was observed when 10 % sodium hydroxide solution over 3 hrs incubation was used. while, the lowest level (0.11)% was observed when 6% sodium hydroxide after 1hr reaction was used, demonstrating that the reaction time and alkaline concentration has very significant role in furfural formation .
