早期关于植物化学防御食草病的理论强调，显性和隐性植物主要由不同类型的化合物来防御。越来越多的证据表明，在表观植物中发现了数量和质量上的防御，它们可以对食草动物起到防御作用。对吉普赛蛾文献的调查表明，不仅有大量的定性化合物和预期的定量化合物，而且吉普赛蛾不受欢迎的寄主与生物碱的存在有关。对鹅掌柴、红枫和山茱萸三种树种的叶片进行了检测，证实了生物碱和其他主要次生代谢产物的存在。已知的倍半萜内酯、脂肪内酯和糖衍生物利洛糖醇是L的组成成分。郁金香树叶，以及以前只在肉豆蔻中发现的二苯丙烷。生物碱含量[即(−)-N-甲基巴豆碱含量]很低，叶片的六氯环己烷检测呈阳性。离开OFA。Rubrum L.进行了革兰氏杆菌的检查，但没有检测到。佛罗里达山茱萸中未检测到生物碱。
Early theories on plant chemical defense against herbivory emphasized that apparent and unapparent plants were primarily defended by different types of compounds. More and more evidence suggests that both quantitative and qualitative defenses are found in apparent plants and that they can play a defensive role against herbivores. A survey of the literature on the gypsy moth suggests not only that there is a large variety of qualitative compounds, as well as the expected quantitative ones, but that unfavored hosts of the gypsy moth are associated with the presence of alkaloids. Foliage of three tree species,Liriodendron tulipiferaL.,Acer rubrumL., andCornus floridaL., was examined to confirm the presence of alkaloids and other major secondary metabolites. The known sesquiterpene lactone, lipiferolide, and the sugar derivative, liriodendritol, were components ofL. tulipiferaleaves, along with a bisphenylpropanoid previously found only in nutmeg. Alkaloid content [i.e., (−)-N-methylcrotsparine content] was low and leaves tested positive for HCN. Leaves ofA. rubrumL. were examined for the presence of gramme, but none could be detected. No alkaloids were detected inCornus florida.
