Other traditional uses include the treatment of yaws, leprosy and skin diseases. They are scented and are highly attractive to bees and other insects. In cultivation this is an advantage as it is easier to harvest.

Work is ongoing on other aspects of L. Seven prominent compounds in leaf make up Methanol extract 10 g was further partitioned between aqueous methanol and ethylacetate to give the ethylacetate fraction.

Phytochemical analyses of the leaf ethylacetate extract yielded two triterpenoids [1 and 2] see Table 5. Distribution Table Top of page The distribution in this summary table is based on all the information available. The plant is an active anti-arthritic remedy utilized with 3 other plants in Igbo tribal ethnomedicine [11]. The leaf residue and stem interface were also obtained as fractions.

The acid in ulcer treatment, inhibits the enzymes that metabolize the prostaglandins, PGE 2a to their inactive metabolites. This is reported for the first time. Volatile oils from leaf L and stem bark B were obtained by hydro-distillation, using an all-glass apparatus adapted to British Pharmacopeia specifications and gave good yields of 0.

Partitioning of methanol extract of dried leaf of Lonchocarpus cyanescens with ethylacetate gave the ethylacetate extract, which was chromatographed using gradient elution.

The ethylacetate fraction 2 g was chromatographed on silica gel column eluting with increasing gradient of n-hexane: Phytochemical screening of stem, leaf, and root methanol extracts of Lonchocarpus cyanescens reveal presence of following seven classes of metabolites: The plant has alternate leaves, flat fruits which are 1 – 5 seeded, oblong pod pointed at both ends [].

These natural products are also responsible for the taste effects utilized in flavoring [17]. Don’t need the entire report?

Received April 5 th; revised May 6 th; accepted June 7 th Melting points were measured on a Gallenkamp melting point apparatus. American Journal of Plant Sciences Vol. Leaf and stem essential oils of Lonchocarpus cyanescens Benth.

Lonchocarpus cyanescens (PROSEA) – PlantUse English

Their investigation revealed that linolenic and oleic acids are its dominant fatty acids with neutral lipids. This species belongs to the third largest family of flowering plants, known as the legumes cyanesvens Leguminosae or Fabaceae — and to a group within this family known as the pea-flowered or papilionoid legumes, Papilionaceae. Thin layer chromatographic separations were carried out on Merck precoated silica gel sheets 60 F 0.

Oleanane derivatives and glycyrrhetinic acid are responsible for the antiinflammatory properties and relief of peptic ulcers observed in L. Similar fractions as determined by TLC were pooled together giving 10 combined fractions.

Each was loaded on reversed phase HPLC, and was further purified by recrystallization. Results show seven compounds were responsible for Comparison lonchocxrpus the chemical compositions of leaf and stem volatile oils.

We report our studies on volatile and phytochemical metabolites of one of them, a Fabaceae—Lonchocarpus cyanescens leaf, stem and root.

West African Plants

This paper presents details of above results which are new in literature. The effect of the extracts on spontaneous motor activity was also studied in the open field test in mice. Above mentioned metabolites may be responsible for literature acclaimed bio-activities L. A decoction of leafy twigs and roots is given to women during or after childbirth and is also taken as an aphrodisiac. Seven compounds in leaf made up It belongs to the family Sterculiaceae and is common in semi-deciduous rainforests from Sierra Leone to Gabon and Congo, including secondary forests where it may fill gaps as a pioneer species.

Flowering takes place in May when upright spikes, cm long, of lilac-blue pea flowers are produced where the vine is in full light.

Lonchocarpus cyanescens – Wikipedia

Further details may be available for individual references in the Distribution Table Details section which can be selected by going to Generate Report. Dubey [19] were used in establishing classes of secondary metabolites present in each fraction.

Phytochemical screenings indicated extracts contain seven important classes of secondary metabolites which are saponin, tannin, steroid, terpenoid, cardiac glycoside, phlobatannins and flavonoids Table 4.

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