Three new humulane-type sesquiterpenes, 8-O-(p-coumaroyl)-5beta-hydroperoxy-1(10)E,4(15)-humuladien-8alpha-ol (1), 8-O-(3-nitro-p-coumaroyl)-1(10)E,4(15)-humuladien-5beta,8alpha-diol (2) and 8-O-(p-coumaroyl)-1(10)E,4(5)E-humuladien-8-ol (3), and a new copaborneol derivative, 1-O-p-coumaroyl-copaborneol (4), have been isolated from the methanol extract of Pileacavaleriei Lévl. subsp. crenata C. J. Chen. Their structures were elucidated using spectroscopic methods. Cytotoxic and antimicrobial activities of the isolated compounds were evaluated.
从光叶火炭母(Pileacavaleriei Lévl. subsp. crenata C. J. Chen)的甲醇提取物中分离出三种新的葎草烷型倍半萜,8-O-(对香豆酰基)-5β-氢过氧基-1(10)E,4(15)-葎草二烯-8α-醇(1)、8-O-(3-硝基-对香豆酰基)-1(10)E,4(15)-葎草二烯-5β,8α-二醇(2)和8-O-(对香豆酰基)-1(10)E,4(5)E-葎草二烯-8-醇(3),以及一种新的异龙脑衍生物,1-O-对香豆酰基-异龙脑(4)。通过光谱方法阐明了它们的结构。对分离得到的化合物进行了细胞毒性和抗菌活性评估。
