The aerial parts of Erigeron annuus (L.) PERS., E. philadelphicus L. and E. sumatrensis RETZ. (Compositae) have been investigated chemically. A new sesquiterpenoid, 6beta,14-epoxyeudesm-4(15)-en-1beta-ol (1), and a new diterpenoid, philadelphinone (6), have been isolated from E. philadelphicus. Four new sesquiterpenoids, (7R*)-opposit-4(15)-ene-1beta,7-diol (2), 11-methoxyopposit-4(15)-en-1beta-ol (3), 15-methoxyisodauc-3-ene-1beta,5alpha-diol (4) and 10alpha-hydroxycadin-4-en-15-al (5), have been isolated from E. annuus. Compounds 2 and 4 were also isolated from E. sumatrensis. The structures of the new compounds were elucidated on the basis of their spectral data.
对一年蓬(Erigeron annuus (L.) PERS.)、费城飞蓬(E. philadelphicus L.)和苏门答腊飞蓬(E. sumatrensis RETZ.)(菊科)的地上部分进行了化学研究。从费城飞蓬中分离出一种新的倍半萜类化合物,6β,14-环氧桉叶-4(15)-烯-1β-醇(1),以及一种新的二萜类化合物,费城飞蓬酮(6)。从一年蓬中分离出四种新的倍半萜类化合物,(7R*)-对映-4(15)-烯-1β,7-二醇(2)、11-甲氧基对映-4(15)-烯-1β-醇(3)、15-甲氧基异胡萝卜-3-烯-1β,5α-二醇(4)和10α-羟基杜松-4-烯-15-醛(5)。化合物2和4也从苏门答腊飞蓬中分离得到。根据新化合物的光谱数据阐明了它们的结构。
