生长在沙特阿拉伯的紫红桧Juniperusphoenicea L.的叶子具有特殊的芳香味,从中检定了3种非氧化倍半萜烯和5种双萜以及1种木酚索。作者在室温下以石油醚-乙醚-甲醇(1:1:1)提取,冷甲醇脱脂,硅胶柱部分分离得3个部位。部位I为石油醚和石油醚-乙醚(9:1)洗脱,是germacrene D、(艹律)草烯(humulene)和石竹烯(caryophyllene)(3:6:1)的混合物。部位Ⅱ为石油醚-乙醚(3:1)洗脱,用TLC分得枞醛(abietinal),transcommu-nic acid和4-表枞酸(4-epiaoietic acid)的混合物(1:1)以及枞醇(abietinol)部位Ⅲ为石油醚-乙醚(1:1)和乙醚洗脱,用HPLC离析(RP8,甲醇-水=17:3),得到脱氧鬼臼毒素
The leaves of Juniperus phoenicea L., which grows in Saudi Arabia, have a special aroma, from which 3 non-oxidized sesquiterpenes and 5 biguanides and 1 kind of wood phenols were identified. The authors extracted with petroleum ether-ether-methanol (1:1:1) at room temperature, degreased the methanol with cold methanol, and partially separated three sites on the silica gel column. Site I was eluted with petroleum ether and petroleum ether-ether (9:1) and was a mixture of germacrene D, humulene, and caryophyllene (3:6:1). Fraction II was eluted with petroleum ether-diethyl ether (3:1) and a mixture of abiaptan, transcommu-nic acid and 4-epiaoietic acid (1:1) and quinone were obtained by TLC. The abietinol site III was eluted with petroleum ether-ether (1:1) and ether, and separated by HPLC (RP8, methanol-water = 17:3) to give deoxypodophyllotoxin.
