天蚕叶片的植物化学研究。（荨麻科）中分离出四种三萜（1-4）、三种黄酮c -苷（5-7）、两种黄烷-3-醇（8,9）、两种黄烷木质素（10,11）和两种原花青素（12,13）。所有化合物均为首次从该菌中分离得到。这是首次报道在荨麻科植物中存在arjunolic acid (4), cinchonain Ia（10）和cinchonain Ib（11）。在荨麻科植物中发现黄烷木质素支持了这样一种可能性，即这种化合物在木兰科植物中比以前认为的更常见。
Phytochemical investigation of the leaves of Cecropia schreberiana Miq. (Urticaceae) led to the isolation of four triterpenoids (1–4), three flavone C-glycosides (5–7), two flavan-3-ols (8, 9), two flavanolignans (10, 11), and two proanthocyanidins (12, 13). All compounds were isolated from C. schreberiana for the first time. This is the first report demonstrating the presence of arjunolic acid (4), cinchonain Ia (10), and cinchonain Ib (11) in the Urticaceae family. The occurrence of flavanolignans within the family Urticaceae supports the likelihood that such compounds are more common within the class Magnoliopsida than previously thought.
