- 摘要:
- 以采自四川省汉源县富林镇、九襄镇、乌斯河镇、宜东镇、富庄镇、清溪镇6个镇的“大红袍”花椒为试材，采用蒸馏法、有机溶剂萃取法、凯氏定氮法、原子吸收分光光度法、氨基酸分析等方法对汉源县6个镇“大红袍”花椒的挥发油、醇溶抽提物、不挥发性乙醚抽提物、蛋白质、矿质元素以及氨基酸六大指标进行了营养成分比较研究，以探究花椒营养成分是否受地域影响。结果表明：地域差异对汉源6个镇的“大红袍”花椒的醇溶提取物、不挥发性乙醚抽提物、无机元素含量、氨基酸含量影响较大，对挥发油和蛋白质成分以及必须氨基酸组成（SRC）影响不大。6个镇的“大红袍”花椒醇溶提取物、不挥发性乙醚抽提物之间存在显著性差异，比值分别为1.902和1.152；而挥发油、蛋白质含量间无显著性差异；无机元素、氨基酸的最大与最小含量差异显著，比值分别介于1.314～4.235、1.262～1.692；人体必需氨基酸半胱氨酸+甲硫氨酸（Cys+Met）为0.340～0.446，与含量最高的赖氨酸（Lys）为1.794～2.069的氨基酸比值系数（RC）值差异显著，最大值比最小值（Max/Min）分别为1.3、1.2；氨基酸比值系数分（SRC）均大于75，Max/Min值为1.408，差异不显著。
- Abstract:
- Taking Zanthoxylum bungeanum Maxim that collected from six towns of Hanyuan county of Fulin，Jiuxiang，Wusihe，Yidong，Fuzhuang，Qingxi as material，with the method of distillation，organic solvent extraction，kjeldahl determination，atomic absorption spectrophotometry and amino acid analysis，the contents of six indexes of volatile oil，alcohol soluble extract，unvolatile ethyl ether extract，protein，mineral elements and amino acids of Zanthoxylum bungeanum Maxim were studied.The results showed that planting areas significantly influenced extracts dissolved in alcohol，unvolatile extracts，the contents of inorganic elements and amino acids in Z.bungeanum Maxim collected from six areas of Hanyuan，but was not significantly impacted on volatilization oil，protein and essential amino acids(SRC).All the contents of extracts dissolved in alcohol，unvolatile extracts had significant difference in six towns of Hanyuan county，the ratios were 1.902 and 1.152 separately；but volatile oil，protein in the prickly-ash had no significant difference among them；the maximum-to-minimum-content difference of each inorganic element and amino acid had distinct，and maximum-to-minimum ratios were from 1.314 to 4.235，and from 1.262 to 1.692；the RC on the human body essential amino acids（Cys+Met） was 0.340～0.446 and Lys was 1.794～2.069，it had significant difference for them，the ratios of Max/Min were 1.3 and 1.2 separately；SRC was greater than 75，the ratio of Max/Min was 1.408，had no significant difference.
