Steroidal glycoalkaloids (SGAs) are secondary metabolites in solanaceae and some liliaceae plants. SGAs have resistance against pathogen, pest attacks and allelopathic effect for the plants themselves. Although SGAs can inhibit the growth of cancer cells and influence the food favor, accumulation of the high SGA level in potato (Solonum tuberosum L.) tubers may cause poisoning for human and livestock to consume, even lead to death. Therefore, it is very important that SGAs content among potato cultivar tuber are determined accurately and its dynamic changes is understood for consumption. For these reasons, the research trend of SGAs content, in this section, was analyzed, and the results showed that the quantity of publications in the field of SGAs increased steadily year by year. The study scope in this yield had being spanned across a wide range of disciplines, which became a trend. The relevant researchers and research institutions are summarized in this field via statistical analysis.
