Abstract: 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.

Key words: eggplant, &alpha, -solanine, HPLC, content, distribution
