IDENTIFICATION
Plant Morphology
Annona muricata is a shrub or small tree, 3.0–10.0 m in height, low-branching and bushy but slender because of its upturned limbs. Leaves have an offensive smell, normally evergreen, are alternate, smooth, glossy and is dark green on the surface, lighter beneath; oblong, elliptic or narrow obovate, pointed at both ends and is 6.25–20 cm long and 2.5–6.25 cm wide. Flowers may appear anywhere on the trunk, branches or twigs and is borne singly, short stalked, 4–5 cm long, plump, in a triangle-conical shape, have 6 petals, with 3 yellow green slightly spreading fleshy petals as the outer layer and 3 pale yellow close-set petals as the inner petals. Fruit is compound and covered with a reticulated, leathery-appearing but tender, inedible, bitter skin from which protrude few or many stubby, or more elongated and curved, soft, pliable spines, more or less oval or heart-shaped, some times irregular, lopsided or curved, due to improper carper development or insect injury, size ranges from 10–30 cm long and up to 15 cm in width, weight may be up to 4.5–6.8 kg, the tips break off easily when the fruit is fully ripe, skin is dark-green in the immature fruit, becoming slightly yellowish-green before the mature fruit is soft to the touch. Seed is a single oval, smooth, hard, black seed, 1.25–2.0 cm long [ 4 , 5 ].

The treatment group was given 300 mg of ethanol soluble fraction of A. muricata dried leaves water (ESFAM) capsule per day after breakfast for eight weeks. Peripheral blood sample was drawn at the end of the study period and the blood samples were centrifuged to obtain serum for ex vivo study.
