The plant has alternate leaves, flat fruits which are 1 – 5 seeded, oblong pod pointed at both ends []. Comparison between the chemical compositions of leaf and stem volatile oils. Yoruba indigo contains indigotin, the same pigment as in Asian indigo Indigofera tinctoria but in smaller amounts. The anti-inflammatory activity of L. The presence of these secondary metabolites was confirmed by thin-layer chromatography. A triterpene component of the plant has been found active against arthritis [2,12,13].

American Journal of Plant Sciences Vol. It has some additional pharmacological properties including antiviral, antifungal, anti-protozoal, and antibacterial activities. Oleanane derivatives and glycyrrhetinic acid are responsible for the antiinflammatory properties and relief of peptic ulcers observed in L.

The antipsychotic effects of the extracts were assessed using the amphetamine animal model of psychosis in rats. TLC with high Rf was used in monitoring elution. Leaves are used as locnhocarpus.

Yoruba indigo Philenoptera cyanescens syn. The extract was concentrated to give dark green solid Seven compounds in leaf made up Chemical composition of the essential oil of Lonchocarpus cyanescens leaf.

Received April 5 th; revised May 6 th; accepted June 7 th The two oils contain hydrocarbons [L 6. Other compositions in leaf are ketone 2.


West African Plants

Classes of phytochemical compounds identified in Lonchocarpus cyanescens [fabaceae] stem, leaf and root methanol and hexane fractions. The acid in ulcer treatment, inhibits the enzymes that metabolize the prostaglandins, PGE 2a to their inactive metabolites.

In Senegal, the leaves are used as a condiment eaten with couscous. 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.

The ethylacetate fraction 2 g was chromatographed on silica gel column eluting with increasing gradient of n-hexane: In Benin, leaf sap is drunk against intestinal disorders and dysentery. The plant is an active anti-arthritic remedy utilized with 3 other plants in Igbo tribal ethnomedicine [11].

The effect of the extracts on spontaneous motor activity was also studied in the open field test in mice. Phytochemical screenings indicated extracts contain seven important classes of secondary metabolites which are saponin, tannin, steroid, terpenoid, cardiacglycoside, phlobatannins and flavonoids Table 4.

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. This increases the level of prostaglandins in digestive system.

We suggest these reported metabolites are responsible for the acclaimed bio-activities L. See images of our work on Flickr. Preliminary phytochemical screening showed the presence of alkaloids, anthraquinones, cardiac glycosides, cyanogenetic glycosides, flavonoids, saponins, steroids and tannins in the leaves of LC. The triterpenes act against arthritis [2,11,12,15,16]. 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].

Roots and stems contain compounds with proven anti-arthritic effects. These natural products are also responsible for the taste effects utilized in flavoring [17].


West African Plants – A Photo Guide – Lonchocarpus cyanescens (Schumach. & Thonn.) Benth.

They are pounded, fermented and dried lonchocsrpus balls about 10cm across which are sold in markets to dye fabrics and tint the hair. It also has antitussive properties, effective as expectorant, treatment of ulcer, and flavoring for masking bitter taste of drugs like quinine.

There are no pictures available for this datasheet Lonchoacrpus you can supply pictures for this datasheet please contact: Phytochemical screening of stem, caynescens, and root methanol extracts of Lonchocarpus cyanescens reveal presence of following seven classes of metabolites: When several references are cited, they may give conflicting information on the status.

Phytochemical analyses of the leaf ethylacetate extract yielded two triterpenoids [1 and 2] see Table 5. Taken together, these findings suggest that the extracts possess phytochemically active constituents with antipsychotic property.

Similar fractions as determined by TLC were pooled together giving 10 combined fractions. Thin layer chromatographic separations were carried out on Merck precoated silica gel sheets 60 F 0. Each was loaded on reversed phase HPLC, and was further purified by recrystallization.

One or more of the features that are needed to cyanexcens you the maps functionality are not available in the web browser that you are using.

A decoction of leafy twigs and roots is given cyaneacens women during or after childbirth and is also taken as an aphrodisiac. Leguminosae—Papilionoideae, Fabaceae is a deciduous scan dent shrub []. Phytochemical screenings indicated extracts contain seven important classes of secondary metabolites which are saponin, tannin, steroid, terpenoid, cardiac glycoside, phlobatannins and flavonoids Table 4. This is reported for the first time.
