The active principle is the alkaloid mescaline. At least eight other alkaloids have been isolated and may play minor roles in hallucinations.54Hagers Handbook lists mescaline (C11H17NO3), N-methylmescaline (C12H17NO4), N-formylmescaline (C12H17NO4), N-acetylmescaline (C13H19NO4), 3-demethylmescaline (C11H15NO4), N-formyl-3-demethylmescaline (C10H15NO3), N-acetyl-S-demethylmescaline (C,2H17NO4), 3,4-dimethoxyphenethylamine (C10H15NO2), tyramine (C8H11NO), N-methyltyramine (C9H13NO), hordenine (C10H15NO), candicine (C17H110NO2), anhalamine (C11H15NO), N-formylanhalamine (C12H15NO4), N-ace-tylanhalamine (C11H17NO4), anhalanine (C12H,7NOO. etc.33

Further separation and purification of the C fraction led to the isolation of seven alkaloids isolated for the first time from the genus Hippeastrum, including trans-dihydronarciclasine (1) (Varró et al. 2017), N-chloromethylnarcissidinium (2) (Hoshino 1998), narciprimin (3) (Nair et al. 2011), narciclasine-4-O-β-d-xylopyranoside (4) (Katoch et al. 2020), N-methyltyramine (5) (Kikuchi et al. 2010), 3β,11α-dihydroxy-1,2-dehydrocrinane (6) (Sener et al. 1993) and brunsvigine (7) (Hong et al. 2008) (Figure 1). Detailed NMR spectroscopic data of all previously known isolates are in publications cited above.
