用轻质石油提取丹尼尔海藻的木材,得到了新的二萜酸,ozozic酸(l; R = CO 2 H)以及相应的醇ozol(l; R = CH 2 OH)。我们从D. oliveri的木材中分离出了丹尼尔酸,一种最早从同一棵树的油脂树脂中获得的呋喃类二萜。迄今为止,从丹尼尔氏菌属中分离出来的所有二萜都属于类固醇的对映体立体化学系列。

population of Helianthus maximiliani from south-central Texas was shown to have a sesquiterpenelactone chemistry which was completely different from that reported for collections of this species from Kansas and north-central Texas. A series of five new guaianolides, two germacrolides ( trans , trans -1(10),4(5)-germacradienolides), one of which is new, and a known labdane diterpeneacid were isolated
摘要 来自德克萨斯州中南部的一个向日葵种群被证明具有倍半萜内酯化学,这与来自堪萨斯州和德克萨斯州中北部的该物种的集合所报道的完全不同。从氯仿提取物中分离出一系列五种新愈创木酚内酯、两种germacrolides(反式、反式-1(10),4(5)-germacradienolides),其中一个是新的,以及一种已知的拉丹二萜酸。通过光谱和化学方法确定结构。一种愈创木酚内酯的结构先前已通过 X 射线晶体学确定。

petroleum gave a new diterpene acid, ozic acid (l; R = CO2H) as well as the corresponding alcohol, ozol (l; R = CH2OH). From the wood of D. oliveri we have isolated daniellic acid, a furanoid diterpene first obtained from the oleo-resin of the same tree. All the diterpenes so far isolated from the genus Daniellia belong to the antipodal stereochemical series with respect to the steroids.
