摘　　要：[目的]测定不同海拔地衣中松萝酸含量。[方法]以不同海拔的地衣为材料,乙酸乙酯为溶剂,通过高效液相色谱法(HPLC)测定不同海拔的暗腹黄梅、淡腹黄梅、喇叭粉石蕊中松萝酸含量。[结果]淡膜黄梅中松萝酸含量最高,为0.7891%,其次为暗腹黄梅,喇叭粉石蕊中最低。[结论]不同地衣体中松萝酸含量与海拔无明显关系,松萝酸含量与种间亲缘关系有关。[Objective]To determine the content of usnic acid from lichens growing at different elevations.[Method]Using lichens at different elevations as materials and ethylacetate as extraction solvent,contents of usnic acid in Xanthoparmelia tinctina,Xanthoparmelia mexicanna and Cladonia chlorphaea were determined by HPLC.[Result]The content of usnic acid in Xanthoparmelia mexicanna was highest,followed by Xanthoparmelia tinctina and Cladonia chlorphaea.[Conclusion]Content of usnic acid in lichen which was closely related with species had nothing to do with altitude.
