  26-hydroxyecdysone 生成 蜕皮激素 、 蜕皮激素 、 3-epi-26-hydroxyecdysone 、 Coronatasterone 、 3-epi-20,26-dihydroxyecdysone 、 20,26-二羟基蜕皮激素 、 alkaline earth salt of/the/ methylsulfuric acid

  名称：

  High-performance liquid chromatography of ecdysone metabolites applied to the cabbage butterfly, Pieris brassicae L

  摘要：

  HPLC allowed separation of twelve major labeled compounds after injection of 3H-ecdysone into Pieris pharate pupae. These compounds were identified as six pairs of metabolites (3 alpha and 3 beta epimers), comprising ecdysone, 20-hydroxyecdysone, 26-hydroxyecdysone, 20,26-dihydroxy-ecdysone and the polar metabolites P and 20-hydroxy-P. These last two products could not be enzymatically split by any hydrolase tested and are weak acids arising respectively from 26-hydroxyecdysone and 20,26-dihydroxyecdysone. They might be 26-oic compounds. Epimerization appears as a fundamental inactivation process in Pieris and could well be a general characteristic of closed systems (eggs and pupae). No significant amounts of hydrolyzable conjugates were detected in our biological system (pharate pupae and pupae).
