A phytochemical investigation on the aerial parts of Laggera pterodonta resulted in the isolation and identification of fourteen compounds, including six sesquiterpenoids (1–6), five flavonoids (7–11), one lignan (12), and two pyrrole alkaloids (13, 14). Among them, compounds 1–3, 7–9, and 11 are the characteristic class of secondary metabolites of L. pterodonta. Compounds 4 and 5 were firstly isolated from L. pterodonta and this is the first report of the presence of compounds 6, 10, and 12 from the genus Laggera. Pyrrole alkaloids 13 and 14 may serve as potential chemotaxonomic markers for L. pterodonta and could be used to distinguish among species of Compositae.

通过对翼状龙（Laggera pterodonta）地上部分进行植物化学研究，分离并鉴定了14种化合物，包括6个倍半萜类化合物（1 – 6），5个黄酮类化合物（7 – 11），1个木脂素（12）和2个吡咯生物碱（13，14）。其中化合物1 - 3，7 - 9，和11是特性类的次生代谢产物的L.灵丹。首先从中分离出化合物4和5L.灵丹，这是化合物的存在的第一报告6，10，和12从该属臭。吡咯生物碱13和14可以作为翼龙L.的潜在化学分类标记，并可以用来区分菊科植物。
