From Lophophora williamsii var. caespitosa, pellotine, anhalidine, anhalonidine, and anhalamine were obtained as phenolic alkaloids, and lophophorine was isolated as a nonphenolic alkaloid, which all belong to the tetrahydroisoquinoline system. A kind of betaine-type yellow components, anhalotine (=Y1=I), Y2 (II), Y3 (III), and peyotine (=Y4=IV) were isolated. They were the derivatives of 6, 7-dimethoxy-3, 4-dihydro-8-hydroxy isoquinolinium innersalt. Similar types of tautomerism were found in I and IV, and they had pKa 6.0 and 6.5, respectively. Another type of tautomerism was found in II and III. II had pKa1 5.6 and pKa2 10.9, and III had pKa1 6.7 and pKa2 11.4.
