Anonas is a tree growing to a height
of 10 meters or less. Leaves are shiny, oblong to oblong-lanceolate, up to
20 centimeters long, 2 to 5 centimeters wide, pointed at the tips, with petioles 1 to 1.5
centimeters long. Flowers are greenish-yellow, fragrant, 2 to 2.5 centimeters long, occurring
in two or three together on lateral peduncles. Outer petals appear as in atis; the inner one is very small, narrowly oblong, or wanting. Fruit is large, heart-shaped,
brownish-yellow, about 8 centimeters or more in diameter, with pentagonal areoles
outside. Skin is thin, covering a cream-colored, fair-flavored, juicy, and sweet

• Phytochemicals / Acetogenins: Study isolated two annonaceous acetogenins from the seeds of Annona reticulata: squamone and isoannonareticin. (2)
• Anthelmintic: Study showed the ethanol extract of Annona reticulata exhibited anthelmintic activity, taking less time to cause paralysis of the earthworms, Pheretima posthuma. Activity was attributed to a compound present in fraction of the ethanol extract. (3) Extracts from the bark of A reticulata showed potent anthelmintic activity. (6) An ethanol extract of seeds showed potent anthelmintic activity against Pheretima posthuma when compared to the chloroform extract, but less potent when compared to standard drug. (26)
