Extraction of roots of Patrinia rupestris (Pall.) Juss. gave a new iridoid compound, 1β,3α-diethyloxy-7-hydromethyl-4-(3-methyl-butyryloxymethyl)-cyclopenta-4(4a),7(7a)-diene[c]pyran-6-one (1), together with a known compound, (1α,4aα, 6α,7β,7aα)-[4a,5,6,7,7a-hexahydro-6,7-dihydroxy-1-(3-methyl-1-oxobutoxy) cyclopenta[c]pyran-4,7-diyl]bis(methylene) 3-methyl-butanoic acid ester (2). The structure of 1 was characterised by HRESIMS, IR, UV, 1-D NMR and 2-D NMR methods. Compound 2 was isolated from this genus for the first time.
从佩兰（Patrinia rupestris （Pall.）Juss.）中提取得到了一个新的裂环环烯醚萜类化合物，1β,3α-二乙氧基-7-羟甲基-4-(3-甲基丁酰氧甲基）-环戊-4(4a),7(7a)-二烯[c]吡喃-6-酮（1），以及一个已知化合物，（1α,4aα,6α,7β,7aα）-[4a,5,6,7,7a-六氢-6,7-二羟基-1-(3-甲基-1-氧代丁氧基）环戊[c]吡喃-4,7-二基]双（亚甲基）3-甲基丁二酸酯（2）。化合物 1 的结构通过高分辨质谱、红外、紫外、一维核磁共振和二维核磁共振方法得到了表征。化合物 2 是首次从该属植物中分离得到的。
