apparicine造句

• The biosynthesis of apparicine requires alteration of the usual tryptamine side chain with loss of C-1.
• The process of apparicine dehydrogenation followed by oxidation with permanganate enables identification of the location of the two piperidine ring carbon substituents.
• Takayama and colleagues ( 2016 ) synthesized conolidine and apparicine through a gold ( I )-catalyzed exo-dig synthesis of a racemic piperidinyl aldehyde.
• Research on " Aspidosperma pyricollum " has led to the discovery that apparicine is biosynthesised from tryptophan by " loss of C-2 and retention of C-3 ".
• In studies of " T . pachysiphon ", it was found that alkaloid content including that of apparicine was greatest in young leaves and leaves receiving greater shade, and varied with leaf age, plant age, and provenance.
