| 摘 要： | 采用HPLC-ELSD法对桑植株各部位所含的1-脱氧野尻霉素(DNJ)进行了含量测定,使用TSKgel Am-ide-80(4.6 mm×250 mm,5μm)色谱柱,流动相为:乙腈-水(84∶16,6.5 mM醋酸铵),流速为1.00 mL/min,柱温:30℃,线性范围为0.505μg～20.2μg(r=0.9991,n=6),平均回收率为94.95%(n=5),RSD=1.98。测定结果表明,野桑叶、嫩枝和根皮部位的DNJ含量较高,而家桑的叶、枝皮和根皮中含量较高。本方法准确度高、重现性好,能快速检测桑树资源及类似植物和相关产品中1-脱氧野尻霉素的含量。

| Abstract: | The content of 1-deoxynojirimycin(DNJ) in mulberry resources was determined by HPLC with an evaporative light scattering detector(ELSD).The HPLC method was established using TSKgel Amide-80(4.6 mm×250 mm,5 μm) column with acetonitrile-water(84∶16 containing 6.5 mM ammonium acetate) as mobile phase.The flow rate was 1.00 mL/min,column temperature 30 ℃.The standard curve for DNJ using ELSD was linear in the range of 0.505 μg ~ 20.2 μg,r=0.9991(n=6).The average recovery was 94.95%(n=5),RSD=1.98%.The results showed that the contents of DNJ in mulberry leaves,root barks,and twigs were higher than other parts of Morus australis.And the contents of DNJ in mulberry leaves,branch bark,and root barks were higher than other parts of M.alba.The method was accurate and reproducible.It could be used for the rapid determination of DNJ in mulberry resources and other related products. |
