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oxyphyllonesE(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.
