Distribution characteristics of solanine content in different organs of potato
We extracted the solanine of three varieties at various organs in different growth stages by water extraction method.The content of solanine in stems,tubers,flowers and leaves of potatoes during their growth and development were determined by high performance liquid chromatography.The dynamic change and distribution of solanin content in different organs of potato during budding,flowering and harvesting stages were discussed,in a study to provide a reference basis for feed safety,food safety,solanine extraction and a physiological mechanism of solanine formation.The results showed that the order of all varieties of solanine content in different sampling times was Jizhangshu No.8>Qingshu No.9>Atlantic.Three varieties in the bud stage showed organ-solanine content was significantly higher than that of stem and leaf.Solanine content of Jizhangshu No.8 and Qingshu No.9 young tubers were significantly higher than those in other organs in the flowering period.The Atlantic solanine content in leaves was significantly higher than other organs.In the budding stage leaves,stems solanine allocation ratio of Jizhangshu No.8,Qingshu No.9 and the Atlantic was 35∶65,39∶61,44∶56;in the flowering period.,solanine allocation ratio in leaves,stems,flowers,tubers was 27∶18∶34∶21,29∶21∶34∶16,27∶23∶26∶24;in harvest period,solanine allocation ratio in leaves,stems,tubers was 21∶52∶27,33∶42∶25,31∶44∶25.The stem played an important role in the accumulation and distribution of solanin.
