摘要

The subject of this study is the structure and composition of buried Phoebe zhennan wood. Through comparative studies of the anatomy and composition with modern undegraded wood, the objective was to understand any changes that have taken place in the P. zhennan buried wood samples. The P. zhennan buried wood can be identified by wood structure characteristics and volatile components analysis. It is required that the microstructural features are identical to those of modern P. zhennan wood; simultaneously, the volatile components of the wood must contain six characteristic compounds with the same peak retention time. The P. zhennan buried wood sample which was used in the experiment was dated 8035-7945 BP (95.4% probability). Further research showed that the cell wall of P. zhennan buried wood had been damaged, the hemicellulose was heavily degraded but there was no obvious degradation of crystalline cellulose. Moisture was present mainly as free water and large amounts of mineral elements such as Fe, and Ni were detected in the ash of P. zhennan buried wood. Both the buried and modern wood of P. zhennan were acidic.

Zhennan埋藏木样品日期为8035-7945 BP（概率为95.4％）。进一步的研究表明，P.正南埋藏木材的细胞壁已被损坏，半纤维素较大，但结晶纤维素没有明显降解。水分主要作为游离水和大量的矿物元素如Fe，并且在P. Zhennan埋藏木材的灰烬中检测到Ni。埋葬和现代木材都是酸性的。
