Plant Habitat

 

A digitata commonly grow in the thumb woodland of the Africa Savana, which are characterised by low attitudes with limited annual rainfall such as the sudano –sahelian zone (600 to 900 mm annual rainfall). It is found in hot, dry woodland on Stoney, well drained soils in frost- free areas that received low rainfall, but adopt to any soil (Le Flamboyant, 1993). A. digitata is resistance to fire, termite and drought, prefers a high water table and is very sensitive to water logging and frost. It is a protected species often planted and associated with human occupation (Giffard, 1974).

Plant Description

 

A digitata is a characteristic tree of size 15-20 m long; trunk very large, and thick, about 20 m in diameter, hard, spongy, with large tortuous branches, usually spread out and contorted (Malgras, 1992); bark greyish brown and normally smooth but can often be variously folded and seamed from years of growth; leaves alternate digitata with entire or denticulate margin, and composed of six to seven leaflets, obovate or ovate, acuminate, acute, slightly pubescent on the surface, flowers large, white, solitary, pendulous (10-20 cm), with very long stalks up to 80 cm (Malgras, 1992; Kerharo and Adam, 1974). Flowers provided with two bracteoles bloom at night; fruits are capsules called monkey bread, which are oblong, ovoid or rounded, woody and hairy, 8-15 cm wide, suspended at the end of a long stalk (Malgras, 1992); fruit epicarp is greenish, at maturity contain numerous black hard seed in white floury pulp.

Plant Uses

 

A digitata is used to treat general worm infestations, diarrhoea and abdominal pain (Diehl et al., 2004). Root or stem bark decoction is used as a disinfectant for chronic wounds. Juice from fresh stem bark is applied to small inflammated boils, whilst a powder mixed with lannea microcarpa seed oil is applied to large boils (Inngjerdinggen et al., 2004). Stem bark decoction is administered orally to treat infectious diseases such as sexually transmitted diseases (Magassouba et al., 2007). A. digitata is used for the treatment of fever, diarrhoea, haemoptysis, hiccups and urinary and digestive tract disorders (Ribeiro et al., 2010; Van Wyk, 2008). Dried leaves are stored for 1-2 years in an air tight container pounded and strained and the resulting gum used as remedy for tooth decay. Some healers recommend adding a dried snail shell before pounding the leaves. Decoction of the leaf is also used orally for the treatment of malaria (Nguta et al., 2010a; 2010b). In some parts of the Africa, India, Sri Lanka and the West Indians malaria sufferer are said to take a mash associated with the disease whilst the bark of the plant is used to treat turbaculousis, persistence cough, bronchitis debility (Luo et al., 2011; Ribeiro et al.,2010).
Biological and pharmacological activities
Aqueous, methanol and acetonitrile extracts of the flower showed promising anti-fungal activity against Microsporum canis, Trichophyton rubrum and Epidermphyton floccosum (Locher et al., 1995). Deeni and Sadiq (2002) have reported in vitro antibacterial and anti-fungal activities (Diehl et al., 2004). A digitata leaves, fruit- pulp and seed have sown antiviral activity against influenza virus herpes simplex virus and respiratory syncytial virus, polio.The plan has analgesic anti- inflammatory, and antipyretic properties Ramadan et al. (1993) found that the fruit pulp of baobab has similar anti- inflammatory properties to phenybutazone in rats. Leaf powder is an anti- asthmatic (Sallet et al., 1946). Intravenous administration of the leaf extract in animals cause a fall in carotid pressure and an increased respiratory rate with increasing amplitude. Several studies have reported the antioxidant capabilities of baobab fruit pulp, which is thought to be due to its high vitamin C content (Lamien-Meda et al, 2008; biomhoff et al., 2010). Besides having analgesic properties, the fruit pulp has also been shown to lower elevated body temperature without affecting normal body temperature (Ramadan et al., 1993). Al- Qarawi et al., (2003) have also reported that the fruit pulp has both hepatoprotective and hepatorestorative properties in Wistar male albino rats.
