Abstract: Nine chemical components and twelve mineral elements in bamboo wood of Phyllostachys edulis Pachyloen from native and introduced habitats were studied. The diversity of bamboo wood among native and introduced habitats were revealed by two-tail variance analysis，meanwhile，bamboo age was referred to as an accessory factor in taking the significance test. Results from the native and introduced habitats showed significant differences for mineral elements （P＜ 0.05） but not for the main chemical components. Content （in gg－1） from the native habitat was as follows：lignin （0.290 0），cellulose （0.395 6），pentosan （0.260 3），cold water extract （0.055 3），hot water extract （0.064 6），benzene-ethanol extract （0.027 7），ash （0.015 7），and SiO2 （0.001 5） as well as 10.0 gkg－1 NaOH extract （0.298 2）. The sequence of mineral element content was K ＞ N ＞ P ＞S = Mg ＞ Fe ＞ Ca ＞ Mn ＞ Al ＞ Zn ＞ Cu ＞ B in the native habitat，but S ＞ Mg ＞ Ca Fe in the native habitat. The main chemical components in bamboo wood from introduced habitat were consistent to native habitat values，which affirm that the genetic stability of Phyllostachys edulis Pachyloen.［Ch，2 tab. 17 ref.］
