A new lupane- (1) and a new oleanane-type (2) triterpenoid, together with a known compound, massagenic acid G, were isolated from the cones of Liquidamber styraciflua. The structures of 1 and 2 were determined as 6beta,30-dihydroxy-3-oxolup-20(29)-en-28-oic acid and 3alpha-hydroxy-11-oxoolean-12-en-28-oic acid, respectively, on the basis of spectroscopic methods and chemical conversion. Compound 1 and several structural analogues were evaluated for cytotoxicity against the P388 (murine lymphocyte leukemia) and the A549 (human lung cancer) cell lines.
从北美枫香树的球果中分离出一种新的羽扇豆烷型(1)和一种新的齐墩果烷型(2)三萜类化合物,以及一种已知化合物——致幻酸G。基于光谱方法和化学转化,分别确定了1和2的结构为6β,30 - 二羟基 - 3 - 氧代羽扇 - 20(29) - 烯 - 28 - 酸和3α - 羟基 - 11 - 氧代齐墩果 - 12 - 烯 - 28 - 酸。对化合物1和几种结构类似物进行了针对P388(小鼠淋巴细胞白血病)和A549(人肺癌)细胞系的细胞毒性评估。
