摘　　要：通常在20～25℃条件下检测澳大利亚或引进我国南方种植1～6年生互叶白千层树所产的原油,其旋光度为+5°～15°(右旋),但在国内南方经引种栽培6～9年后发现原来为正值(右旋)的旋光度有的会降低进而出现负值(左旋)。这种变化对原油的主要组份含量没发现影响,而对油的物理性状如芳香味有一定影响。这种变化经初步分析研究表明很可能是由于原产澳大利亚的互叶白千层树引进中国南方种植多年后受栽培环境的改变而产生的。The polargraphic degree of extracted oil of Melaleuca altemifolia L. introduced from Australia was ＋5° - 15° （dextrorotary）, obtained from 6-9 years-old trees. However, after 6-9 years cultivation, the polargraphic degree had changed into negative values（levorotary）. This change did not alter the main constituents of the extracted oil, but it did result in some physical property changes, like fragrance. It was suggested that these changes might be influence caused by the adaptation through years in the south China ecological regions.
