Kigelia africana (Lam.) Benth. - syn.Kigelia pinnata (Jacq.) DC.; Kigelia abyssinica A.Rich.; Crescentia pinnata Jacq.; Bignonia africana Lam. - Bignoniaceae \\
sausagetree, **Leberwurstbaum**

Evergreen or deciduous tree, up to 12m high, native to tropical Africa; leaves opposite, odd-pinnate, 20-60cm long; leaflets ovate, elliptic or obovate; flowers big, opening at night and falling down at morning, with unpleasant smell, dark red or maroon-coloured, borne on pedulous stalks adapting them to pollination by bats; fruits long (30-90cm), thick (10-18cm), heavy (5-8kg), fleshy, grey, rounded on both ends, liverwurst-like, with scabrous bark and numerous seeds in the pulp. \\
The fruit, rarely the bark, is used for wound-healing and skin care. \\

"Kigelia africana is a plant used in Africa for anti-inflammatory, anti-microbial, and anti-skin-aging effects. Various papers have reported on the composition and biological activities of its CH2Cl2 extracts and dermal formulations. Chemical analysis of a polar extract of fruit from K. africana indicated the presence of  [[http://www.chemblink.com/products/50932-19-9.htm|verminoside]]  (1), an iridoid, as a major constituent, and of a series of polyphenols such as verbascoside (2). In vitro assays showed that 1 had significant anti-inflammatory effects, inhibiting both iNOS expression and NO release in the LPS-induced J774.A1 macrophage cell line. Cytotoxicity and cutaneous irritation of the extract and of compounds 1 and 2 were investigated. The crude extract and 1 did not affect cell viability in vitro either in cells grown in monolayers (ML) or in the reconstituted human epidermis (RHE, 3D) model; neither caused release of pro-inflammatory mediators or histomorphological modification of RHE." \\

Verminoside (6-O-(3,4-Dimethoxycinnamoyl)-catalpol), also found in Kigelia pinnata, has twofold antiamoebic activity against Entamoeba histolytica compared to the standard drug metronidazole. \\
