高良姜根茎中一个新的杜松烷型倍半萜

摘要

AIM:To investigate the chemical constituents of the rhizomes of Alpinia officinarum.METHODS:Compounds were isolated by various column chromatographic methods,and their structures were identified based on their physicochemical properties and spectral data.RESULTS:A cadinane sesquiterpene,alpiniaterpene A (1),was isolated.Its structure with absolute configuration was established by means of HR-ESI,NMR,and quantum chemical CD calculation.CONCLUSION:Compound 1 is a new compound.%目的:对高良姜(Alpinia officinarum Hance)根茎的化学成分进行研究.方法:运用多种色谱技术分离纯化,通过理化常数和光谱数据鉴定化合物的结构.结果:分离鉴定了1个杜松烷型倍半萜类化合物,命名为alpiniaterpene A,此外还利用量子化学计算方法对该化合物的绝对构型进行了确证.结论:化合物1为新化合物.
