The project concerns assembling chemical and ultrastructural data in order to establish the way natural products function in plants as well as their role in coevolutionary systems involving plants and animals. The investigation emphasizes the phenolics, terpenoids and alkaloids present in members of the Compositae genera Helianthus and Artemesia, as well as other genera including especially Passiflora and Salvia. The antiherbivore, antimicrobial, allergenic contact dermatitis and antitumor activity of the isolated compounds are studied. The patterns of compounds encountered are used as genetic markers to understand phylogenetic relationships. New sequiterpene lactones, diterpene acids and flavonoid aglycones and their O- and C-glycosides have been isolated and structurally characterized by UV, NMR and MS spectral data as well as chemical derivatization and transformation.

该项目涉及组装化学和超微结构数据，以便 建立天然产品在植物中的运作方式以及它们在 涉及动植物的协同进化系统。 调查 强调酚类，萜类化合物和生物碱成员中存在的生物碱 复合属属Helianthus和Artemesia以及其他属包括 尤其是小虫和萨尔维亚。 抗小动物，抗菌，过敏性 研究了分离化合物的接触性皮炎和抗肿瘤活性。 遇到的化合物的模式被用作理解的遗传标记 系统发育关系。 新的丝氨酸内酯，二萜酸和 类黄酮类糖酮及其O-和C-糖苷已被隔离，并且 结构上以紫外线，NMR和MS光谱数据以及化学特征 衍生和转换。
