In cultivation this is an advantage as it is easier to harvest. Phytochemical screenings indicated extracts contain seven important classes of secondary metabolites which are saponin, tannin, steroid, terpenoid, cardiacglycoside, phlobatannins and flavonoids Table 4. 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.

Bioactivity effects of Lonchocarpus cyanescens have been demonstrated in its anti-inflammatory, anti-arthritic and its relief on ulcer. Chemical composition of the essential oil of Lonchocarpus cyanescens stem. The extract was concentrated to give dark green solid Lonchocarpus cyanescens LC is a medicinal plant commonly used in combination with other recipes in the treatment of psychotic disorders in traditional medicine.

Partitioning of methanol extract of dried leaf of Lonchocarpus cyanescens with ethylacetate gave the ethylacetate extract, which was chromatographed using gradient elution. Plant was authenticated at the Herbarium, Department of Botany, University of Ibadan, Ibadan, where voucher samples were lonchoxarpus and signed certificate of identification was obtained [Prof Lonchocarpuss and Mr Donatus O.

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. Leaf, stem and root cold methanol extracts of Lonchocarpus cyanescens were fractionated using distilled hexane to get methanol and hexane fractions.

Lonchocarpus cyanescens

The leaf residue and stem interface were also obtained as fractions. Thin layer chromatographic separations were carried out on Merck precoated silica gel sheets 60 F 0. Don’t need the entire report? Similar fractions as determined by TLC were pooled together giving 10 combined fractions.

Leaves are used as laxative. We report our studies on volatile and phytochemical metabolites of one of them, a Fabaceae—Lonchocarpus cyanescens leaf, stem and root. This study was designed to examine whether the aqueous and ethanolic extracts of LC possess antipsychotic property in rats.

In Nigeria, this decoction is used to treat arthritic conditions, venereal diseases and diarrhea. More plant samples for extractions were obtained from a farmland in the University of Ibadan Campus, Nigeria and identified by Dr. The distribution in this summary table is based on all the information available. 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. Their investigation revealed that linolenic and oleic acids are its dominant fatty acids with neutral lipids.

More information about modern web browsers can be found at http: The ethylacetate fraction 2 g was chromatographed on silica gel column eluting with increasing gradient of n-hexane: Yoruba indigo contains indigotin, the same pigment as in Asian indigo Indigofera tinctoria but in smaller amounts. Results of our recent studies revealed forty plants were utilized as anti-malaria herb [1].

Standard methods such as N. Leaf and stem essential oils of Lonchocarpus cyanescens Benth. Oleanane derivatives and glycyrrhetinic acid are responsible for the antiinflammatory properties and relief of peptic ulcers observed in L. Work is ongoing on other aspects of L.


A decoction of leafy twigs and roots is given to women during or after childbirth and is also taken as an aphrodisiac. The triterpenes act against arthritis [2,11,12,15,16]. This paper presents details of above results which are new in literature. Flowering takes place in May when upright spikes, cm long, of lilac-blue pea flowers are produced where the vine is in full light. Leguminosae—Papilionoideae, Fabaceae is a deciduous scan dent shrub [].

Preliminary phytochemical screening showed the presence of alkaloids, anthraquinones, cardiac glycosides, cyanogenetic glycosides, flavonoids, saponins, steroids and tannins in the leaves of LC. Roots and stems contain compounds with proven anti-arthritic effects.

Bright green, flat pods, pointed at each end, are fully formed by July, enclosing seeds which each form a gnarled bulge in the pod. Phytochemical screenings cyanesfens extracts konchocarpus seven important classes of secondary metabolites which are saponin, tannin, cyanecsens, terpenoid, cardiac glycoside, phlobatannins and flavonoids Table 4. We suggest these reported metabolites are responsible for the acclaimed bio-activities L. Phytochemical analyses of the leaf ethylacetate extract yielded two triterpenoids [1 and 2] see Table 5.

The two oils contain hydrocarbons [L 6. It also has antitussive properties, effective as expectorant, treatment of ulcer, and flavoring for masking bitter taste of drugs like quinine.

More leaf of L. This is reported for the first time. Phytochemical screening of stem, leaf, and root methanol extracts of Lonchocarpus cyanescens reveal presence of following seven classes of metabolites:
