of Helianthus debilis subsp. cucumerifolius, H. occidentalis and H. simulans afforded a variety of known and some unknown ent-kauranoic acids. H. occidentalis gave, in addition, ciliaric acid and a new biogenetically related atisane derivative occidentalic acid. H. simulans gave the heliangolide leptocarpin and the flavone hymenoxin in addition to ent-kauranes. Several of the diterpenoids from these
Helianthus debilis subsp 的抽象空中部分。cucumerifolius、H. occidentalis 和 H. simulans 提供了多种已知和一些未知的 ent-kauranoic 酸。此外,H. occidentalis 还提供了纤毛酸和一种新的生物遗传学相关的 atisane 衍生物 occidentalic acid。除了 ent-kauranes 之外,H. simulans 还提供 heliangolide leptocarpin 和黄酮 hymenoxin。来自这些物种的几种二萜类化合物抑制了向日葵蛾的幼虫生长。
