![]() The wolf apple tree is the natural host of the larva of the butterfly Leucanella memusae. Solanum lycocarpum fruit extracts have also been shown to kill larvae of the Culex mosquito. It is believed that the fruits protect the maned wolf from infection of the giant kidney worm, which is usually fatal for the animal. The main phenolic compounds in ethanol extracts of the ripe fruits are caffeic acid and chlorogenic acid. Extracts have been shown to kill in vitro the human parasites Schistosoma mansoni and Giardia lamblia, Leishmania amazonensis, and Leishmania infantum. The fruit contains about 1.5% of glycoalkaloids in its dried fruits, chiefly solamargine and solasonine, mostly in the peel and seeds. High-fiber Solanum lycocarpum flour was found to reduce diabetes symptoms in diabetic rats however, the starch did not show such effect. About 30% of the starch extracted from almost-ripe fruits, which commercialized as capsules, is digestion-resistant, which seems to be the rationale for these popular uses. Medicine Ĭurrently, there are no proven medicinal uses for the wolf apple, but the plant is used in the local folk medicine for obesity, cholesterol reduction, and as a treatment for diabetes. However, the leaves are eaten by cattle, and are also an important food source for the bat Platyrrhinus lineatus. Īll other parts of the plant are poisonous to humans. The main volatiles in the ripe fruit are hexanal (which has the scent of grass) and ethyl butanoate (scent of apple), although dozens of other compounds contribute to the fruit's aroma. The pulp of the ripe fruit contains about 75% moisture, 11% carbohydrate, 1% fat, 1% protein, 1% ash, 2.5% soluble fiber, and 2% insoluble fiber. The starch is locally separated by blending the fruit with water and straining. The dry pulp, without peel and seeds, yields over 50% starch, more than cassava. The fruits are used as a fallback source of food for cattle in the dry season.Īt the onset of maturation, the whole fruit contains 85% moisture (by weight), 5% starch, and 10% other residue. The ripe fruits are edible to humans, and are consumed by local populations in jams and preserves, but the unripe fruits are quite rich in tannin. The maned wolf is an important seed-spreading agent. They resemble the tomato in external shape and internal morphology, but also the eggplant for the texture and color of the flesh. The pulp is yellowish, soft, sweetish and extremely aromatic. The rind is thin and lustrous, and remains green even after ripening. The fruits are large, up to 20 cm (8 in) in diameter and weighing 900 g (2 lb) or more, and contain up to 500 dark brown comma-shaped seeds, about 7 mm × 5 mm × 2 mm ( 1⁄ 4 in × 3⁄ 16 in × 1⁄ 16 in). įruit production occurs mostly between December and January. fuscata, Bombus morio, Exomalopsis sp., Pseudaugochloropsis graminea, Apis mellifera, and Megachile benigna. frontalis, Oxaea flavescens, Centris scopipes, C. ![]() The latter produce fruit after cross-pollination by several species of pollen-collecting bees, including Xylocopa virescens, X. Flowers lack nectar, and are either male or hermaphroditic. The flowers are arranged in helical monochasal cyme, opening from the base up. The flowers are similar to those of the bitter nightshade: star-shaped, with five sepals, five blue or purple petals fused at the base, and five large yellow anthers that release pollen through an opening at the tip. Plants flower through the year, but more intensely during the dry season, from late fall to early spring. ![]() The large leaves are 16 to 28 cm (6 to 11 in) long, simple but deeply lobed, tough, and covered in a soft grey-white fuzz, in alternate disposition. The wolf apple plant is a flowering shrub or small tree with round open crown, ranging in height from 1.2 to 5 m (4 to 16 ft). It prefers moist, clay soil, full sun, and mild temperatures. The native range of the wolf apple tree is the Brazilian savannah, but it grows also on pastures and disturbed land, such as highway margins, in various parts of Brazil. Likewise, the scientific name " lycocarpum" is formed from Latinized Greek elements " lyco-", meaning "wolf", and " carpum" meaning "fruit". The name "wolf apple" comes from the fact that they account for more than 50% of the maned wolf's diet. The plant is called lobeira ("wolf's plant") or fruta-do-lobo ("wolf's fruit") in Portuguese. Solanum lycocarpum, or wolf apple, is common in the Brazilian savanna, the Cerrado ecoregion. ![]()
