黄檀属和紫檀属6种红木化学组成及pH值的研究

对黄檀属和紫檀属6种红木化学成分、金属元素含量及酸碱性质进行测定分析。结果表明，交趾黄檀和柬埔寨黄檀木材除了灰分区别较大外，其他的化学成分含量相近；同属不同树种木材的化学组成存在差异。6种红木均含有丰富的Ca元素；不同红木中各种金属元素的含量有差异，金属元素含量的大小次序也不同，檀香紫檀木材中没有检测到Mn、Cu元素，交趾黄檀木材中没有检测到Cu元素。交趾黄檀和柬埔寨黄檀木材的金属元素（除了Na）差异较大。黄檀属和紫檀属6种红木均偏酸性。

Contents of Chemical Components and Metals in the Wood in Dalbergia Genus and Pterocarpus Genus

Contents of chemical components, metals and pH of six kinds of rosewood in Dalbergia genus along with Pterocarpus genus were determined and analyzed. The results showed that chemical components of D. cochinensis wood were similar to D. cambodian wood except for ash content. There were differences in chemical components between different wood species belong to the same genus. Metal element species and their contents of six different rosewood were different, except that six rosewoods in Pterocarpus genus and Dalbergia genus contained rich Ca, Cu and Mn element were not detected in P. santalinus and Cu was not detected in D.cochinensis. Metal contents of D. cochinensis wood and D. cambodiana wood varied greatly except Na. Six rosewoods in Pterocarpus genus and Dalbergia genus wood showed slightly acidic.
