【摘要】 本文报告自报春花科排草属植物零陵香(Lysimachia foenumgraecum Hance)的全草提取出挥发油,收率0.17%,呈黄绿色,具浓厚芳香。用气相色谱-质谱-计算机联用仪(Finnigan4021型)进行了挥发油成分分析,结果在零陵香挥发油中共鉴定出59个成分;其中酸性成分20个,以十六酸(hexadecanoic acid)、十七酸(heptanoic acid)等含量较多;中性和酚性成分39个,以六氢金合欢烯酰丙酮(hexahydrofarnesylacetone)等的含量较多,它在植物中是较罕见的成分,并且是首次在零陵香植物中发现。本文还用气相色谱仪(Perkin-Elmer Sigma 2B 型)和标准品对零陵香挥发油中成分进行了对照鉴定。更多还原

【Abstract】 1.The present paper reports that 0.17% fragrant,yellowish green co- lored volatile oil was obtained from Lysimachia foenumgraecum Hance by steam distil- lation with the following physical constants: n_D²⁰ 1.4824,d₁₅¹⁵ 0.9059,[α]_D²⁵—18.6 （c=1.1,CHCI₃）. 2.From the volatile oil a large amount of palmitic acid was separated and iden- tified by its mp,elementary analysis and IR. 3.The volatile oil was divided into the acidic portion,the constituents in which were later transferred into their methyl esters （A）,and the neutral and phenolic por- tion （B）.（A） and （B） were analyzed by GC and GC-MS.The result of analysis show- ed that a total of 59 chemical constituents were indentified in the volatile oil;（A） con- sisted of 20 and （B） consisted of 39 constituents. 4.From the results as shown in the GC figures 1 and 2,hexahydrofarnesylacetone, being a rarely occured constituent in the natural product,and dibutyl phthalate might be considered to be the principal neutral costituents,just as the hexadecanoic acid and margaric acid to be the principal acidic constituents in the volatile oil of Lysimachia foenumgraecum Hance.更多还原
