These natural products are also responsible for the taste effects utilized in flavoring [17].

Methanol extract 10 g was further partitioned between aqueous methanol and ethylacetate to give the ethylacetate fraction. Classes of phytochemical compounds identified in Lonchocarpus cyanescens [fabaceae] stem, leaf and root methanol and hexane fractions.

However, in contrast to chlorpromazine, a typical antipsychotic, the extracts did not induce cataleptic behaviour in the animals.

There are no pictures available for this datasheet If you can supply pictures for this datasheet please contact: The two oils contain hydrocarbons [L 6. The effect of the extracts on spontaneous motor activity was also studied in the open field test in mice. Leguminosae—Papilionoideae, Fabaceae is a deciduous scan dent shrub []. Leaves are used as laxative. lochocarpus

This is reported for the first time. Seven prominent compounds in leaf make up We report lonchocarphs studies on volatile and phytochemical metabolites of one of them, a Fabaceae—Lonchocarpus cyanescens leaf, stem and root.

Lonchocarpus cyanescens

The ethylacetate fraction 2 g was chromatographed on silica gel column eluting with increasing gradient of n-hexane: This study was designed to examine whether the aqueous and ethanolic extracts of LC possess antipsychotic property in rats.


Distribution Maps Top of page You can pan and zoom the map. Cold soaked methanol extract which was defattened with hexane, and volatile oils of leaf Lstem B and root R of Lonchocarpus cyanescens prominently utilized as antimalaria in Nigerian ethno-medicine were screened. Standard methods such as N.

We have identified more promising families of Nigerian plants from our collations of standardized questionnaires on anti-malaria herbs utilized in South-western Nigeria ethno-medicine comprising of Ogun, Oyo and Lagos states. In cultivation this is an advantage as it is easier to harvest. The acid in ulcer treatment, inhibits the enzymes that metabolize the prostaglandins, PGE 2a to their inactive metabolites.

West African Plants

This species belongs to the third largest family of flowering plants, known as the legumes — Leguminosae or Fabaceae — and to a group within this family known as the pea-flowered or papilionoid legumes, Papilionaceae.

The antipsychotic effects of the extracts were assessed using the amphetamine animal model of psychosis in rats. Plant was authenticated at the Herbarium, Department of Botany, University of Ibadan, Ibadan, where voucher samples were deposited and signed certificate of identification was obtained [Prof Ayodele and Mr Donatus O.

Yoruba indigo contains indigotin, the same pigment as in Asian indigo Indigofera tinctoria but in smaller amounts. Preliminary phytochemical screening showed the presence of alkaloids, anthraquinones, cardiac glycosides, cyanogenetic glycosides, flavonoids, saponins, steroids and tannins in the leaves of LC.

The leaf residue and stem interface were also obtained as fractions. The whole shrub of Lonchocarpus cyanescens were collected from Ago-Iwoye, Ogun-State, Nigeria for extraction of its volatile oils. Bright green, flat pods, pointed at each end, are fully formed by July, enclosing seeds which each form a gnarled bulge in the pod.


More information about modern web browsers can be found at http: Fractions were subjected to phytochemical analysis. Flowering takes place in May when upright spikes, cm long, of lilac-blue pea flowers are produced where the vine is in full light.

The plant is an active anti-arthritic remedy utilized with 3 other plants in Igbo tribal ethnomedicine [11]. It also has antitussive properties, effective as expectorant, treatment of ulcer, and flavoring for masking bitter taste of drugs like quinine. Other traditional uses include the treatment of yaws, leprosy and skin diseases. Comparison between the chemical compositions of leaf and stem volatile oils.

Lonchocarpus cyanescens – Wikipedia

Glass column of varying sizes depending on weight of extract and silica gel 70 – mesh were used for open column chromatography. Thin layer chromatographic separations were carried out on Merck precoated silica gel sheets 60 F 0. See images of our work on Flickr.

Melting points were measured on a Gallenkamp melting point apparatus. A triterpene component of the plant has been found active against arthritis [2,12,13].
