摘要
目的研究神香草Hyssopus cuspidatus干燥地上部分的倍半萜类化学成分。方法采用D101大孔吸附树脂、硅胶柱色谱、ODS、Toyopearl HW-40C、Sephadex LH-20以及半制备HPLC等方法进行分离纯化,根据理化性质以及波谱数据对化合物进行结构鉴定。结果从神香草95%乙醇提取物中分离得到15个化合物,分别鉴定为3-eudesmene-1β-11-diol(1)、4-eudesmene-1β,11-diol(2)、1β,11-dihydroxy-5-eudesmene(3)、ent-4(15)-eudesmen-1α,11-diol(4)、7α,11-dihydroxy-cadin-10(14)-ene(5)、eudesmane-1β,5α,11-triol(6)、5-epi-eudesma-4(15)-ene-1β,6β-diol(7)、4(15)-eudesmene-1β,6α-diol(8)、(7R*)-opposit-4(15)-ene-1β,11-diol(9)、cryptomeridiol(10)、octahydro-4-hydroxy-3α-methyl-7-methylene-α-(1-methylethyl)-1H-indene-1-methanol(11)、caryolane-1,9β-diol(12)、(3S,5R,6S,7E)-3,5,6-trihydroxy-7-megastigmen-9-one(13)、spathulenol(14)、4β,10α-aromadendranediol(15)。结论化合物1~15均为首次从该属植物中分离得到。
Objective To study the sesquiterpenes from the aerial parts of Hyssopus cuspidatus. Methods The compounds were isolated and purified by a combination of various chromatographic techniques including D101 macroporous adsorption resin, silica gel,ODS, Toyopearl HW-40 C, Sephadex LH-20, and semi-preparative HPLC. Their structures were elucidated on the basis of physicochemical properties and spectroscopic data. Results Fifteen sesquiterpenes were isolated from the 95% EtOH extracts of H.cuspidatus and their structures were elucidated as 3-eudesmene-1β-11-diol(1), 4-eudesmene-1β,11-diol(2), 1β,11-dihydroxy-5-eudesmene(3), ent-4(15)-eudesmen-1α,11-diol(4), 7α,11-dihydroxy-cadin-10(14)-ene(5), eudesmane-1β,5α,11-triol(6), 5-epieudesma-4(15)-ene-1β,6β-diol(7), 4(15)-eudesmene-1β,6α-diol(8),(7 R*)-opposit-4(15)-ene-1β,11-diol(9), cryptomeridiol(10),octahydro-4-hydroxy-3α-methyl-7-methylene-α-(1-methylethyl)-1 H-indene-1-methanol(11), caryolane-1,9β-diol(12),(3 S,5 R,6 S,7 E)-3,5,6-trihydroxy-7-megastigmen-9-one(13), spathulenol(14), and 4β,10α-aromadendranediol(15), respectively. Conclusion Compounds 1—15 are isolated from the plants of Hyssopus genus for the first time.
