西南不同主产地生姜中6-姜酚含量的测定

Determination of 6-gingerol in ginger from different habitats in southwest China

采用HPLC法测定了西南不同主产地7种生姜中6-姜酚的含量,为生姜在医药保健方面的合理利用提供科学依据。方法:色谱柱为Diamonsil C18(5μm,4.6×250mm);流动相为乙腈∶水=66∶34(体积比);柱温30℃;流速1.0mL/min;波长280nm;进样量:10μL。结果:经检测,贵州长顺和四川键为白口生姜中6-姜酚含量最高,分别为9.7mg/g和9.2mg/g。

This paper determines the contents of 6 -gingerol in seven kinds of medicinal gingers in southwest China, which provides scientific references for reasonable utilization of ginger in medical care and health. Method： Chromatographic column is Diamonsil C18 （51μm,4.6 × 250mm） ; Mobile phase： acetonitrile ： water = 66：34 （volume ratio） ; the column temperature is 30℃ ; The flow rate is 1.0ml/min, the detection wavelength is 280 nm, and the sample volume is 10μl. Result： via detecting： the content of 6 -gingerol in the medicinal ginger of Changshun, Guizhou and Jianwei Baikou, Sichuan is 9.7mg/g and 9.2mg/g respectively, the highest in southwest China.
