Abstract A radioimmunoassay (RIA) procedure for the determination of pmol quantitites of morphine in capsule samples of Papaver somniferum was developed. An antiserum developed against a conjugate of morphine-3-hemisuccinate-BSA was relatively specific for morphine and possessed moderated cross-reactivity with codeine and mild cross-reactivity with thebaine, but none with narceine, papaverine, or noscapine
摘要 开发了一种用于测定嗜眠罂粟胶囊样品中吗啡 pmol 含量的放射免疫分析 (RIA) 程序。针对吗啡-3-半琥珀酸酯-BSA 缀合物开发的抗血清对吗啡具有相对特异性,并且与可待因具有适度的交叉反应性,与蒂巴因具有轻度交叉反应性,但与那赛因、罂粟碱或那斯卡品均无交叉反应性。标准曲线在 0.01–0.20 ng 范围内呈线性。该测定允许快速、灵敏和精确地测定胶囊样品未纯化水提取物中的吗啡。通过放射免疫测定法测定的水性提取物中吗啡的量通过高效液相色谱法 (HPLC) 进行验证。这两种方法显示出很高的相关系数(r = 0。
