摘　　要：本文报遣柄果牛皮叶(Sticta henryana),多形树发(Alectoria variabilis),宽瓣肾岛衣漂白变型(Nephromopsis stracheyi f. ectocar pisma)和顶果珊瑚枝(Stereocaulon pomiferum)四种地衣的化学成分。根据光谱数据分析,从中分离得到的18个化合物被鉴定为5-甲基-β-苔黑酚酸甲酯(methyl 5-methy-β-orcinolcarboxylate),苔色酸(orsellinic acid),扁枝衣酸(everainic acid),苔色酸甲酯(methyl orsellinate),赤星衣酸乙酯(ethyl hematommate),β-苔黑酚酸甲酯(methyl β-orcinolcarboxylate),假杯点素A(pseudocyphellarin A),黑茶渍素(atranorin),茶渍酸(lecanoric acid),斑点酸(stictic acid),降斑点酸(norstictic acid),藻纹苔酸(salazinic acid),富马原岛衣酸(fumarprotocetraric acid),左旋和右旋松萝酸(usnic acid),左旋地衣硬酸〔(-)-lichesterinic acid〕,右旋原地衣硬酸〔(+)-protolichesterinic acid〕和无羁萜(friedelin)。其中5-甲基-β苔黑酚酸甲酯系首次从植物中得到。分析结果表明,顶果珊瑚枝可作为一种较好的苔香型香原料。Following 18 Compouads were isolated and identified from four lichens in china. 1. Sticta henryana Mull. Arg.; methyl 5-methy-β-orciaolcarboxylate, orsellinic acid, everninic acid, methyl orsellinate, pseudocyphellarin A and lecanoric acid. 2. Alectoria variabilis Brystrek: atranorin, lecanoric acid, stictic acid, norstictic acid, salazinic acid, fumarprotocetraric acid and( + )-usnic acid. 3. Nephromopsis strachyi Mull Arg. ectocarpisma Hue. (-)-usnic acid, (-)-lichesterinic acid, (+)-protolichesterinic acid and friedelin. 4. Stereocaulon pomiferum Duvign: ethyl hematommate and methyl β-orcinolcar-boxylate. The analysis showed that the lichen Nephromopsis strachyi f. ectocarpisma is very rich in antibiotic constituents, such as usnic acid and γ-lactonic acids, and that the lichen Stereocaulon pomiferum can be used in producing lichen perfume.
