摘要
从香[Eltholtzia ciliata(Thund.)Hyland]中分出14个化合物,用波谱和化学等方法确定为6-甲基三十三烷(Ⅰ),13-环己基二十六烷(Ⅱ),β-谷甾醇(Ⅲ),棕榈酸(Ⅳ_a),亚油酸(Ⅳ_b),亚麻酸(Ⅳ_c),熊果酸(Ⅴ),5-羟基-6、7-二甲氧基黄酮(Ⅵ),5-羟基-7、8-二甲氧基黄酮(Ⅶ),5、7-二羟基-4′-甲氧基黄酮(Ⅷ),5-羟基-7、4′-二甲氧基双氢黄酮醇(Ⅸ),β-谷甾醇-3-β-D-葡萄糖甙(Ⅹ),5-羟基-6-甲基-7-O-α-D-半乳吡喃糖双氢黄酮甙(Ⅺ),刺槐素-7-O-β-D-葡萄糖甙(Ⅻ)。其中化合物Ⅺ为新化合物,除(Ⅳ_b)和(Ⅳ_c)外,其余为首次从该属植物中得到。
Fourteen compounds have been obtained from the Elsholtzia ciliata (Thund.) Hyland. Their structures were identified by spectral and chemical methods as following:Ⅰ.6-methyl- tritriacontane,Ⅱ.13-cyclohexyl-hexoacosane,Ⅲ.β-sitosterol,Ⅳa.palmitic acid,Ⅳb.linoleic acid,Ⅳc.linolenic acid,Ⅴ.ursolic acid,Ⅵ.5-hydroxy-6,7-dimethoxyflavone,Ⅶ.5-hyd- roxy-7,8-dimethoxyflavone,Ⅷ.5,7-dihydroxy-4'-methoxyflavone,Ⅸ.5-hydroxy-7,4'-dime- thoxyflavone,X.β-sitosterol-β-D-glucoside,Ⅺ.5-hydroxy-6-methylflavanone-7-O-α-D-galacopy- ranoside,Ⅻ.acacetin-7-O-β-glucoside.Among all the compounds,Ⅺ is a new compound.Ex- cept for Ⅳb and Ⅳc,the other twelve compounds were first found in this plant.
