Conclusions
1. The alkaloids perforine and haplophyllidine isolated from the seeds ofH. perforatum have the developed formulas C16H17N(OH)2(OCH3)2(-O-) and C16H16N(OH) (OCH3)2(-O-).
2. Perforine is 7-hydroxy-8-(3′-hydroxy-3′-methylbutyl)-4, 8-dimethoxy-5, 6, 7, 8-tetrahydrofuroquinoline, and haplophyllidine is 7-hydroxy-4, 8-dimethoxy-(3′-methyl-2′-butenyl)-5, 6, 7, 8-tetrahydrofuroquinoline.
3. The transition from perforine to haplophyllidine has been effected by the splitting off of hydrogen chloride from chloroacetylperforine.
