Content Determination and Distribution of α-Solanine in Eggplant

In order to investigate the content and distribution of α-solanine in different varieties eggplant,ultrasonic extraction and high performance liquid chromatography(HPLC) were used to extract and determine α-solanine.The contents of α-solanine in different eggplant organs,eggplants with different fruit colors,fruit harvest periods,fruit maturity and fruit parts were investigated.The results showed that the content of α-solanine in eggplant fruit was the highest among different eggplant organs.The content of α-solanine in purple eggplant was significantly higher than green eggplant,it was the highest in the first fruit among the different harvest periods.The α-solanine content in immature eggplant fruits was significantly higher than that in mature fruits,and the α-solanine content in flesh of eggplant fruits was significantly higher than peel and stalk.
