摘　　要：目的:研究益智仁中的化学成分。方法:硅胶和HPLC等色谱手段进行化学成分的分离纯化,根据波谱数据结合理化性质进行化合物的结构鉴定。结果:从益智仁的70%丙酮/水提取物中分得2个化合物oxyphyllones E(1)和F(2)。结论:化合物1和2为新的降倍半萜类成分。AIM： To investigate the constituents from the fruits of Alpinia oxyphylla Miq. METHOI）ES： Compounds were isolated and purified by various column chromatographic methods. Their structures were determined on the basis of ESI-MS and spectral analyses （including 2D NMR）. RESULTS： Two sesquiterpenes, oxyphyllones E （1） and F （2） were isolated from Me2CO/H20 （70%） extract of the fruit of A. oxyphylla. CONCLUSION： Oxyphyllones E （1） and F （2） are novel 14-norcadinene sesquiterpene and tetranorsesquiterpene, respectively.
