  Kew Scientist - April 1998 Issue 13   (Site not responding. Last check: 2007-10-31)
Two new alkaloids were isolated from the bark of the legume Acosmium panamense by Dr Brian Goodwin while he investigated the claimed anti-diabetic properties of the plant as part of a project managed by Prof.
Acosmium is one of the presumed basal genera in the sub-family Papilionoideae which are a target for legume research at Kew.
The chemistry of basal legumes is being studied by Drs Geoffrey Kite and Nigel Veitch, who determined the structures of the new Acosmium alkaloids (Phytochemistry 45: 847-850, 1997).

The co-occurring leaves are imparipinnate and leaflet position varies from opposite to alternate on a single leaf.
This fossil taxon is not referable to an extant genus, but it is most comparable to several genera in the tribe Sophoreae, including Acosmium, Bowdichia, Diplotropis, Sakoanala, and Maackia.
A precise understanding of relationships of this extinct taxon will require a phylogenetic analysis that includes these and other basal woody papilionoid legumes.

Plants like, Momordica cymbalaria, Urtica dioica, Suzigium cumini, Acosmium panamense etc have shown a great potential as antidiabetics and they have been included in various polyherbal preparations (Sokeng et al., 2001; Ojewole, 2003; Kameswararao et al., 2003; Bnouham et al., 2003; Mainzen et al., 2004; Andrade-cetto and Wiedenfeld, 2004).
Bersama engleriana of the Melianthaceae family is a small tree with spikes of pink and white flowers and, brown capsule containing red seeds with yellow arils; the leaf-rhachides are slightly winged; it is widespread in Africa (Hutchinson and Dalziel, 1958).

 Seasonal changes in photosynthesis of trees in the flooded forest of the Mapire River
and Acosmium nitens (Vog.) Benth); and (2) independence of photosynthesis and leaf conductance from flooding (Eschweilera tenuifolia (Berg.) Miers.).
In the first response pattern, declining photosynthetic rate with flooding may be interpreted as a sign of reduced flood tolerance, whereas the second response pattern may indicate increased flood tolerance.
Keywords: Acosmium nitens, Campsiandra laurifolia, Eschweilera tenuifolia, leaf conductance, Psidium ovatifolium, Symmeria paniculata, tropical forest, water stress, xylem water potential.

They identified the active component as a flavonol glycoside, a Kaempferol derivative, which is not so surprising: "Kaempferol derivatives have already been desribed as hypoglycemic active," said Wiedenfeld.
Meanwhile, the team successfully tested two other plants in rat models: Cecropia obtusifolia, a tree twenty meters tall traditionally called "Guarubo" or "Chancarro," and more recently, Acosmium panamense, a tropical leguminous tree.
This contains "a substance with a new structure," which Wiedenfeld will present at the Society for Medicinal Plant Research annual congress in Kiel in the first week of September 2003.
