Alkaloids Derived From Ornithine: Pyrrolizidine Alkaloids 13

摘要: Pyrrolizidine alkaloids (PAs) occur in about 5% of all flowering plants. They are esters a basic moiety (“Necine”) and esterifying acids (“necic acids”). Up to now, 500 different PAs described. can be hazardous man domestic animal. show cancerogenic, mutagenic, teratogenic, fetotoxic properties. Many intoxications by The level the toxicity each single PA is dependent from its concrete chemical structure. This chapter gives an overview chemistry, biosynthesis, PAs.
