Abstract

Annona muricata Linn, belongs to the family Annonaceae. Oil from seeds of some plants may be used for the production of edible oils and soaps. Finally, many members of this family are used in folk medicines for various purposes. Annona muricata roots are used as antispasmodic, parasiticidal. Flower and flower buds as a bechic. The unripe fruits is useful as anti-scorbutic. Seeda are useful as fish-poison, insecticidal and astringent. The compounds that are isolated from A. muricata are Anomuricine, Anomurine, Coclaurine, Reticuline, Coreximine, Stepharine, Atherosperminine, Anonaine and Liriodenine. On the basis of IR, UV 1H and 13C NMR data, we can decide the Compound AM-3 possess three subunits. The placement of ketocarbonyl group and the THF core on the linear backbone was settled on the basis of analysis of different fragment ions discerned in the E1-MS. The molecular formula of AM-3 was settled as C35H62O7 on the basis of the results of elemental analysis.
