从毛钩藤鲜叶中分离得到9个化合物，分别为熊果酸(1)、β-谷甾基葡萄糖苷(2)、伞形酮(3)、钩藤碱-A(4)、绿原酸(5)、芦丁(6)、新橙皮苷(7)、栎皮苷(8)和叶黄素(9)。用波谱方法确证了它们的结构。其中，乌索酸(I)具有该植物的细胞毒性作用。
Nine compounds, ursolic acid (1), β-sitosteryl glucoside (2), umbelliferone (3), uncarine-A (4), chlorogenic acid (5), rutin (6), neohesperidin (7), quercitrin (8)and afzelin (9) were isolated and characterized from fresh leaves of Uncaria hirsuta. Their structures were elucidated by spectral methods. Among them, uroslic acid (I) exhibited a cytotoxic principle of this plant.
