目的研究松杉灵芝子实体的化学成分。方法采用硅胶、凝胶色谱法进行分离纯化,波谱法进行结构鉴定。结果从乙醇提取物的醋酸乙酯部分分离得到8个三萜类化合物。结构鉴定为:灵芝醇A(ganoderiol A,Ⅰ)、灵芝酮三醇(ganodermanontriol,Ⅱ)、灵芝三醇(ganodermatriol,Ⅲ)、灵芝酸C(ganodericacid C,Ⅳ)、灵芝酸A(gan-odericacid A,Ⅴ)、赤芝酮A(lucidone A,Ⅵ),赤芝酸C(lucidenicacid C,Ⅶ)、赤芝酸LM1(lucidenic acid LM1,Ⅷ)。结论化合物Ⅰ～Ⅷ均为首次从松杉灵芝中分离得到。

Objective To study the chemical constituents from the fruiting bodies of Ganoderma tsugae. Methods To isolate the compounds by silica gel and Sephadex LH-20 column chromatography and to elucidate their structures by means of spectral analyses. Results Eight triterpenoids were obtained from EtOAc fraction of EtOH extract and identified as ganoderiol A (Ⅰ), ganodermanontriol (Ⅱ), ganodermatriol (Ⅲ), ganoderic acid C (Ⅳ), ganoderic acid A (Ⅴ), lucidone A (Ⅵ), lucidenic acid C (Ⅶ), and lucidenic acid LM1 (Ⅷ). Conclusion Compounds Ⅰ-Ⅷ are all isolated from G. tsugae for the first time.
