They are scented and are highly attractive to bees and other insects. See images of our work on Flickr. Each of the oils had distinct characteristic pleasant smell. Preliminary phytochemical screening showed the presence of alkaloids, anthraquinones, cardiac glycosides, cyanogenetic glycosides, flavonoids, saponins, steroids and tannins in the leaves of LC.

Partitioning of methanol extract of dried loncgocarpus of Lonchocarpus cyanescens with ethylacetate gave the ethylacetate extract, which was chromatographed using gradient elution. The two oils contain hydrocarbons [L 6.

This may be the reason why glycyrrhetinic acid is said to relieve peptic ulcers [2,12,15,17].

African whitewood Triplochiton scleroxylon The African whitewood Triplochiton scleroxylonknown as arere in Yoruba and obeche in Bini, is a large fast-growing tree, reaching 65 m ftusually with a straight trunk and buttresses up to about 8 m 26 ft high. The plant has alternate leaves, flat fruits which are 1 – 5 seeded, oblong pod pointed at both ends []. American Journal of Plant Sciences Vol.

Taken together, these findings suggest that the extracts possess phytochemically active constituents with antipsychotic property. Methanol extract 10 g was further partitioned between aqueous methanol and ethylacetate to give the ethylacetate fraction.

Glass column of varying sizes depending on weight of extract and silica gel 70 – mesh were used for open column chromatography. Results show seven compounds were responsible for Phytochemical screenings indicated extracts contain seven important lonchicarpus of secondary metabolites which are saponin, tannin, steroid, terpenoid, cardiacglycoside, phlobatannins and flavonoids Table 4.

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 presence of these secondary metabolites was confirmed by thin-layer chromatography.


Lonchocarpus cyanescens (PROSEA) – PlantUse English

Generate a print friendly version containing only the sections you need. Flowering takes place in May when upright spikes, cm long, of lilac-blue pea flowers are produced where the vine is in full light.

Comparison between the chemical compositions of leaf and stem volatile oils. It has some additional pharmacological properties including antiviral, antifungal, anti-protozoal, and antibacterial activities. The effect of the extracts on spontaneous motor activity was also studied in the open field test in mice. Oleanane cyanfscens and glycyrrhetinic acid are responsible for the antiinflammatory properties and relief of peptic ulcers observed in L. Chemical composition of the essential oil of Lonchocarpus cyanescens stem.

Phytochemical analyses of the leaf ethylacetate extract yielded two triterpenoids [1 and 2] see Table 5.

Lonchocarpus cyanescens

Further details may be available for individual references in the Distribution Table Details section which can be selected by going to Generate Report. Phytochemical screening of stem, leaf, and root methanol extracts of Lonchocarpus cyanescens reveal presence of following seven classes of metabolites: This increases the level of prostaglandins in digestive system.

Above mentioned metabolites may be responsible for literature acclaimed bio-activities L. As the pods ripen at the end of the rainy season, they turn papery and grey-brown with an iridescent sheen and a clearly visible network of raised veins. The distribution in this summary table is based on all the information available. Partitioning of methanol extract from dried leaf of it with ethylacetate gave fraction, which was chromatographed using gradient elution.

In cultivation this is an advantage as it is cyanescns to harvest. This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, loncohcarpus, and reproduction in any medium, provided the original work is properly cited. These natural products are also lonchocarppus for the taste effects utilized in flavoring [17]. Yoruba indigo contains indigotin, the cyanescfns pigment as in Asian indigo Indigofera tinctoria but in smaller amounts.


Lonchocarpus cyanescens

The acid in ulcer treatment, inhibits the enzymes that metabolize the prostaglandins, PGE 2a to their inactive metabolites. More plant samples for extractions were obtained from a farmland in the University of Ibadan Campus, Nigeria and identified by Dr. Other compositions in leaf are ketone 2. One or more of the features that are needed to show you the maps functionality are not available in the web browser that you are using. Leguminosae—Papilionoideae, Fabaceae is a deciduous scan dent shrub [].

We suggest these reported metabolites are responsible for the acclaimed bio-activities L. TLC with high Rf was used in monitoring elution. Thus, this investigation provides evidence that may justify the ethnomedicinal applications of Lonchocarpus cyanescens as the major constituent of the recipe used for the management of psychosis in Nigeria.

GC-MS analyses of the seed oil showed phytol, sterols, beta-tocopherol and hydrocarbons are in the unsaponifiable matters of the oils; while HPLC showed presence of glycolipids [monogalactosyldiacylglycerol, digalactosyldiacylglycerol, digalactosylmonoacylglycerol and monogalactosylmonoacylglycerol].

Visit our blog on Blogspot. Roots and stems contain compounds with proven anti-arthritic effects. Don’t need the entire report? There are no pictures available for this datasheet If you can supply pictures for this datasheet please contact: These prostaglandins inhibit gastric secretion but stimulate pancreatic secretion and mucous secretion in the intestines. We report our studies on volatile and phytochemical metabolites of one of them, a Fabaceae—Lonchocarpus cyanescens leaf, stem and root.

A triterpene component of the plant has been found active against arthritis [2,12,13].

Dubey [19] were used in establishing classes of secondary metabolites present in each fraction. In Nigeria, this decoction is used to treat arthritic conditions, venereal diseases and diarrhea.
