了解木麻黄的再植问题。采用电喷雾电离质谱、H-1和C-13核磁共振谱等技术，从其根中分离鉴定了5种化学成分：12，13-二氢小茴香酸（M-1）、白桦酸（M-2）、3-O-咖啡酰羽扇豆醇（M-3）、儿茶素（M-4）和表儿茶素（M-5）。生物活性测定结果表明，所鉴定的化合物对C.木贼即其自身的萌发和幼苗生长。其中12，13-二氢微粒酸危害最大。这些结果表明，鉴定的化学物质可能是C.木贼再植问题
To understand the replant problem in Casuarina equisetifolia L. plantations, we isolated and identified five chemicals [12, 13-dihydromicromeric acid (M-1), betulinic acid (M-2), 3-O-caffeoyl lupeol (M-3), catechins (M-4) and epicatechin (M-5)] from its roots by electrospray ionization mass spectrometry and H-1 and C-13 nuclear magnetic resonance spectroscopy. Bioassays showed that the identified chemicals were inhibitory to C. equisetifolia i.e. its own germination and seedling growth. Among these, 12,13-dihydromicromeric acid was most harmful. These findings suggested that the identified chemicals may be the key allelochemicals in C. equisetifolia replant problem.
