Nineteen mono- and sesquiterpenoids were identified in the essential oils of the leaves and fruits of ANNONA SENEGALENSIS var. SENEGALENSIS by means of GC and GC-MS. The major constituents were car-3-ene in the fruit oil and linalool in the leaf volatile oil. The quantitative and qualitative composition of the two essential oils were considerably different.
"The plant has been reported to contain in addition, wax, alkaloids (Philipov et al., 1995; You et al., 1995), proteins, amino acids, antraquinones (Bamba et al., 1984; Burkill, 1985; Ekpendu et al., 1998), sterols, glycosides, flavonal terpenoids (Mackie and Misra, 1956; Mackie and Ghatce, 1958; Adesogan and Durodola, 1976; Fatope et al., 1996; Sahpaz et al., 1996) and terpenes (Ekundayo and Oguntimein, 1986).

[Show abstract][Hide abstract] ABSTRACT: Annona senegalensis Pers (family: Annonaceae) is used traditionally in Nigeria to treat victims of snakebite. The potency of the methanol extract of the root bark of the plant was tested against cobra (Naja nigricotlis nigricotlis Wetch) venom in rats. The extract was also tested on brine shrimp (Artemia saline Leach). The activity of the extract against the venom induced mortality, occurrence of toxic signs, activity on liver enzymes as well as its ability to reverse experimentally induced increase in body temperature were evaluated. Results indicated that the extract caused reduction in the induced hyperthermia and directly detoxified the snake venom used by 16-33%. It, however, failed to restore the biochemical functions (sGOT and sGPT) of the liver. The extract exhibited an LC(50) of 232.7 microg/ml in the brine shrimp test.

[Show abstract][Hide abstract] ABSTRACT: The Annonaceae is a tropical to subtropical plant family distributed from Africa, Asia, Central and South America to Australia. It consists of numerous fruit trees (custard apple—Annona atemoya, soursop—A. muricata), plants whose dried fruit are used as condiments (Ethiopian pepper—Xylopia aethiopica, Calabash nutmeg—Monodora myristica and one well-known fragrant flower (ylang ylang—Cananga odorata). The volatile composition of these and numerous other species found in 17 different genera are reviewed.More than 200 volatiles have been identified in these essential oils. These compounds are basically mono- and sesquiterpenoids. Typical constituents include α- and β-pinene, myrcene, p-cymene, limonene, linalool, and 1,8-cineole. The sesquiterpenoids represented the most common group of components. Prenyl indoles, a rare nitro-ethane and a sesquiterpenoid of a novel skeletal type also have been encountered.

[Show abstract][Hide abstract] ABSTRACT: The volatile composition of the fruits of three Annona species from Malaysia was investigated by capillary GC and GC-MS following isolation by simultaneous steam distillation-extraction. A total of fifty-one components were identified in the soursop volatiles, including eleven which have been previously reported in this fruit. Thirty-four volatile components were identified in the sweetsop and fifty-two in the bullock's heart. Most aroma components in the soursop were esters (57.2%), while terpenoid constituents predominated in the sweetsop and bullock's heart (88.5% and 98.3% respectively).
