Abstract: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 106.28-3 770.50 mg · kg-1(DW).Among them,there were 7 potato varieties whose glycoside alkaloid
contents exceeded the safe value 1 000 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.
