摘要 目的 研究滇桑茎皮中的化学成分。方法 应用色谱技术分离纯化,通过理化性质和波谱学方法鉴定化合物的结构。结果 从滇桑茎皮95%乙醇提取物中分离得到11个化合物,分别鉴定为桑树苷C(mulberroside C,1)、oxyresveratrol(2)、2′,4′,7-trihydroxy-(2S)-flavone(3)、norartocarpetin(4)、moracin P(5)、betulinic acid(6)、sitosteryl 3β-glucoside 6′-O-palmitate(7)、lupeol(8)、正丁酸(9)、β-daucosterol(10)、β-sitosterol(11)。结论 化合物1~11均为首次从该植物中分离得到;抗肿瘤筛选结果表明,化合物9显示出一定的抗肿瘤活性。 Objective To isolate and identify the components from the stem barks of Morus yunnanensis. Methods The compounds were isolated and purified by silic gel column, Sephadex LH-20, and RP-18 chromatography. Their chemical structures were elucidated on the basis of physicochemical properties and spectral data. Results Eleven compounds were isolated and identified as: mulberroside C (1), oxyresveratrol (2), 2′, 4′, 7-trihydroxy-(2S)-flavone (3), norartocarpetin (4), moracin P (5), betulinic acid (6), sitosteryl 3t3-glucoside 6′-O-palmitate (7), lupeol (8), betulinic acid (9), β-daucosterol (10), and β-sitos- terol (11). Conclusion All the compounds are isolated from the plant for the first time, and compound 9 shows cytotoxic activities.
