Two new seco-prezizaane-type sesquiterpenoids 1, 2 and two new prenylated phenylpropanoids 4, 5 were isolated along with 15 known compounds from Illicium fargesii. The structures of 1, 2 were elucidated as 10-O-(E)- and 10-O-(Z)-cinnamoyl-2-oxo-6-deoxyneoanisatin by analysis of spectroscopic data and by comparison of their NMR data with those of previously reported 2-oxo-6-deoxyneoanisatin (3), respectively
分离了两个新的癸二氮杂-癸二烷型倍半萜类化合物1、2和两个新的异戊烯基化的苯基丙烷类化合物4、5,以及15种从八角茴香中提取的已知化合物。通过分析光谱数据并将其NMR数据与NMR数据进行比较,阐明1,2的结构为10-O-(E)-和10-O-(Z)-肉桂酰基-2-氧代-6-脱氧新茴香胺。以前分别报道了2-oxo-6-deoxyneoansatin(3),而4,5的结构被鉴定为4-allyl-2-(3-methylbut-2-en-1-yl)phenol和4-allyl-根据光谱数据分别得到2-(2-甲基丁-3-烯-2-基)苯酚。在分离出的化合物中,在DMEM / N2培养基中培养的大鼠皮质神经元中,macranthol(7)被发现具有5--10 microM的神经保护活性。
