Isolation and Structure of Neoannonin, a Novel Insecticidal Compound from the Seeds of Annona squamosa

抄録

Two insecticidal compounds were isolated from the seeds of Annona squamosa. One was identified as annonin (squamocin) and the other was characterized as a novel dihydroxy-bistetrahydrofuran fatty acid lactone (acetogenin) with 35 carbons. These two compounds were toxic to eggs, larvae and adults of the fruitfly.
