of the beyerene type, ent -19-hydroxy-1 7-acetoxybeyer-15-ene and ent -beyer-15-en-17-oic acid, and two previously characterized kauranoids, ent -16β-hydroxy-17-acetoxykaurane and ent -16β,1 7-dihydroxy-kaurane, as well as two known flavonoids, luteolin-7,3′,4′-trimethyl ether and luteolin-7,3′-dimethyl ether, and a triterpenoid, oleanoic acid, were obtained from a chloroform extract of Petunia patagonica
摘要 两种新的拜尔烯型二萜,ent -19-hydroxy-1 7-acetoxybeyer-15-ene 和 ent -beyer-15-en-17-oic acid,以及两种先前表征过的贝壳类,ent -16β-hydroxy-17 -acetoxykaurane 和 ent -16β,1 7-dihydroxy-kaurane,以及两种已知的黄酮类化合物,木犀草素-7,3',4'-三甲醚和木犀草素-7,3'-二甲醚,以及三萜类齐墩果酸,是从矮牵牛的氯仿提取物中获得的。通过光谱数据和化学转化阐明了新结构。
