大血藤挥发性成分研究

Studies on the chemical constituents of the volatile oil from Caulis sargentodoxae

目的 :研究大血藤 (Caulissargentodoxae)挥发性成分。 方法 :利用水蒸气蒸馏法提取大血藤挥发性成分 ,用GC/MS进行分离测定 ,结合计算机检索技术对分离的化合物进行结构鉴定 ,应用色谱峰面积归一化法计算各成分的相对百分含量。结果 :鉴定出 4 6个化学成分 ,大血藤挥发性成分大于 5 %的为δ 荜澄茄烯 1 5 .1 2 5 %,α 杜松醇 1 0 .2 2 9%,δ 杜松醇5 .32 6 %。结论 :4 6个化合物均为首次从大血藤中检出。

AIM: To study the chemical constituents of the volatile oil from Caulis sargentodoxae . METHODS: The oil was obtained by steam distillation. The chemical compositions were separated and identified by GC/MS. The relative contents in the oil were determined by area nomalization method. RESULTS: Forty six kinds of chemical constituents were separated and identified. The major constituents that their relative contents more than 5% were δ cadinen(15.125%), a cadinol(10.229%), δ cadinol(5.326%). CONCLUSION: The forty six compounds from Caulis sargentodoxae were separated and identified for the first time.
