The alkaloid composition of the giant cactus, Carnegiea gigantea Br. & R., was studied. Chromatographic separation led to the isolation of four tetrahydroisoquinoline alkaloids: carnegine, salsolidine, gigantine and arizonine. The structure of the new natural product, arizonine, was establihsed by spectroscopic data and total synthesis via two independent routes. Salsolidine is reported for the first time in the cacti. Also new to this species are 3-methoxytyramine and 3,4-dimethoxypenethylamine, which were identified in the alkaloid extract by gas chromatography-mass spectrometry. Dopamine was isolated from fresh plant material.
对巨柱仙人掌（Carnegiea gigantea Br. & R.）的生物碱成分进行了研究。通过色谱分离法分离出了四种四氢异喹啉生物碱：卡内基碱、去甲乌药碱、巨柱仙人掌碱和亚利桑那碱。新天然产物亚利桑那碱的结构通过光谱数据和两条独立路线的全合成得以确定。去甲乌药碱首次在仙人掌中被报道。该物种中还新发现了3-甲氧基酪胺和3,4-二甲氧基苯乙胺，它们通过气相色谱-质谱法在生物碱提取物中被鉴定出来。从新鲜植物材料中分离出了多巴胺。
