从广西特有的前胡属植物马山前胡Peucedanummashanense根中分得4个化合物，经理化常数和波谱分析，鉴定为3’（R）-（＋）-亥茅酚（Ⅰ），3’（S）-（－）-亥茅酚（Ⅱ），褐煤酸（Ⅲ）和甘露醇（Ⅳ）。化合物Ⅰ为首次从自然界分得，其余均为首次从该植物中分得。 Four compounds were isolated from the roots of Peucedanum mashanense, a pistachio plant native to Guangxi, and their molecular weights were analyzed by the managerial constants and spectroscopy. They were identified as 3’(R)-(+)-helicophenol (I), 3’ ( S)-(-)-Haltol (II), montanic acid (III) and mannitol (IV). Compound I was isolated from nature for the first time, and the rest were first obtained from the plant.
