摘要:

对贵州不同海拔鱼腥草中绿原酸、芦丁、槲皮素、槲皮苷、金丝桃苷、山奈素、异鼠李素、槲皮素-3-O-β-D-葡萄糖苷以及挥发性化学成分行研究,通过HPLC 分析绿原酸和黄酮类化合物,挥发性化学成分利用顶空固相微萃取结合气- 质联用(HS-SPME-GC/MS)进行分析,总挥发油的含量用水蒸气蒸馏提取获得。结果表明:鱼腥中绿原酸和黄酮的含量分别在海拔1400~1500m 和500~600m有较高的含量;鱼腥草精油在海拔600~700m有较高的含量,甲基正壬酮含量随海拔的增加而变化在700~800m 有较高的含量;单萜(蒎烯)、倍半萜(石竹烯(Ⅱ))、脂肪酮(甲基正壬酮)、脂肪酸(羊油酸)和脂肪酸酯(2,6,10,14- 四甲基十五酸甲酯)的含量在不同的海拔有显著的差异。

Abstract:

The chemical composition and volatile compound content of Houttuynia cordata in Guizhou province, China, were investigated at different altitudes. Altitudes were characterized by the evolution of chlorogenic acid, rutin, quercetin, quercitrin, hyperoside, kaempferol, isorhamnetin and quercetin-3-O-β-D-glucoside as well as volatile components. Chlorogenic acid and all flavonoids were analyzed by HPLC. The volatile extracts obtained by steam distillation were analyzed using HS-SPME-GC/MS. The chlorogenic acid and flavonoid content of H. cordata remained high at 1400-1500 m and 500-600 m, respectively. The essential oil content remained high at 600 - 700 m. Pharmacological 2-undecanone varied with increasing altitude, and remained high at 700-800 m. The contents of monoterpene (pinene), sesquiterpene (caryophyllene-(Ⅱ)), fatty ketone (2-undecanone), fatty acid (caprinic acid) and fatty acid ester (pentadecanoic acid,2,6,10,14-tetramethyl-,methyl ester) changed significantly at different altitudes.

Key words: gas chromatography-mass spectrometry (GC-MS), headspace solid-phase microextraction (HS-SPME), high performance liquid chromatography (HPLC), Houttuynia cordata Thunb., metabolites, property, altitudes
