摘 要 ：以不同品种的茄子（Solanum melomgena L.）为试材，采用超声波提取技术和高效液相色谱法对茄子不同器官、不同颜色、不同采收时期和不同成熟度的果实及果实不同部位中α-茄碱进行提取和测定，旨在明确茄子体内α-茄碱的含量及分布特点。结果表明，茄子不同器官中，果实中α-茄碱含量最高；紫茄品种α-茄碱含量显著高于绿茄；不同时期采收的果实中以门茄中α-茄碱含量最高；未成熟茄子果实中α-茄碱含量显著高于成熟的茄子果实；各茄子品种果肉中α-茄碱含量显著高于果皮和果蒂。

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.
