Abstract Metabolism of 12 synthetic d , l -chlorophenylalanines has been examined in several crop and weed plants. Twenty-five gram samples of excised shoots or leaves of bushbean, soybean, corn, pigweed, lambsquarters and giant foxtail were allowed to metabolize 10 −4 M solutions of the d , l -chlorophenylalanines for 24 hr in continuous light. The plant samples were then extracted in 80% methanol
摘要 12 种合成 d , l - 氯苯丙氨酸在几种作物和杂草植物中的代谢情况已被检测。25 克从灌木豆、大豆、玉米、猪草、羊羔和大狗尾草的切下枝条或叶子的样品在连续光照下代谢 10 -4 M d,l-氯苯丙氨酸溶液 24 小时。然后将植物样品用 80% 甲醇提取,并将可溶性酸性代谢物分馏到乙醚中。每种醚浓缩物通过从 PrepSep C18 柱的分级洗脱进行部分纯化,然后通过 HPLC 进行分析。收集的馏分用五氟苄溴酯化并通过 GC-MS 检查以证明存在氯苯乙酸、氯苯甲酸和/或氯肉桂酸的 PFB 酯。
