%X Lignin, a heterogenous polymer which presents about 20-30  in lignocellulose emerged as promising feedstock for the production of specialty chemicals. However, due to lignocellulose recalcitrance structure, the pretreatment is necessary to obtain efficient utilization of biomass. In this work, the preliminary study was carried out focusing on the properties lignin extracted from bamboo (Gigantochloa scortcheninii) using alkali and ionic liquid pretreatment. It was discovered that about 42 and 11 of acid-insoluble lignin has been extracted from alkali and IL pretreatment respectively. The degradation onset temperature of alkali and ionic liquid extracted lignin were found to be 262.20 and 172.41°C. FTIR spectra analysis showed the characteristic peaks of lignin for both samples. Desirable products such as aldehydes, phenol, hydrocarbons and aromatics were identified from pyrolysis GC-MS. © Published under licence by IOP Publishing Ltd.
