摘　　要：采用高效液相色谱-蒸发光散射检测法(HPLC-ELSD)测定我国马铃薯主栽品种块茎糖苷生物碱的含量,并研究不同覆盖方式和烘烤加工对马铃薯块茎糖苷生物碱含量的影响。结果表明:我国51个马铃薯主栽品种块茎糖苷生物碱含量为106.28~3770.50 mg·kg^(-1)(DW),其中有7个品种块茎糖苷生物碱含量超过了安全值1000 mg·kg^(-1)(DW);与未加工处理相比,烘烤后的马铃薯块茎糖苷生物碱含量显著降低,有利于提高马铃薯品种块茎的安全性;黑色地膜覆盖种植的马铃薯块茎糖苷生物碱含量最低,显著低于露地栽培,覆膜后再覆土对块茎糖苷生物碱含量的影响不大,种植马铃薯应采用黑色地膜覆盖方式,从而获得低糖苷生物碱含量的块茎。High performance liquid chromatography-evaporative light scattering detection(HPLCELSD)method was used to measure the content of tuber glycoside alkaloids in main potato cultivars in China.This paper also studied the effects of different mulching methods and tuber processing on the content of potato glycoside alkaloids.The results showed that the glycoside alkaloid content of 51 main potato varieties in China was 106.28-3770.50 mg·kg^(-1)(DW).Among them,there were 7 potato varieties whose glycoside alkaloid contents exceeded the safe value 1000 mg·kg^(-1)(DW).Comparing with those unprocessed,the glycoside alkaloid content of potato tubers decreased significantly after baking,which was beneficial for improving the safety of potato tubers.The content of glycoside alkaloids in potato tubers covered with black plastic film was the lowest,which was significantly lower than that in open field cultivation.Soil mulching after plastic film mulching had little effect on tuber glycoside alkaloid content.So black plastic film mulching should be used to grow potato tubers,thus to obtain tubers with low glycoside alkaloid content.
