滇姜花新二萜成分的研究

从滇姜花中分离并鉴定了５个二萜成分，其中新化合物滇姜花素Ａ，Ｂ的结构经光谱及化学方法推定。     

GC-MS法分析姜花属四种植物的挥发性成分

分析姜花属白姜花、黄姜花、小花姜花、圆瓣姜花这四种植物的挥发性成分。建立了同时蒸馏萃取GC/MS法对这四种植物的挥发性成分进行了分析,并探讨了这四种植物挥发性成分的差异。从四种植物中共分离鉴定了105个挥发性成分,主要是萜类及其含氧衍生物。四种姜花属植物中含有多种活性成分,四者化合物组成相似,但黄姜花中各成分含量与其他三者区别较大。     

Two New Diterpenoids from Hedychium forrestii

Two new labdane diterpenes isolated from the rhizomes of Hedychium forrestii were determined by spectroscopic evidence to be labda-8(17), 11, 13-trien-7β-hydroxyl- 15(16)-olide (1,hedyforrestin B) and labda-8(17), 11, 13-trien-7β,16-dihydroxyl-16(15)-olide (2, hedyforrestinC).     

具有杀菌活性的新型二萜化合物合成

以落叶松醇为原料,分别通过11步反应合成滇姜花E和相关二萜化合物,并对其进行了杀菌活性测试.     

The Reduction of a Natural Diterpene Containing α, β-Unsaturated Keto Group

Hedychenone (1), a diterpene containing α, β-unsaturated keto group, was reduced by aluminum-mercury alloy, and a dimerized product (2) was obtained as the major product. The coupling occurred at β position of the keto group.
