This paper presents details of above results which are new in literature. These prostaglandins inhibit gastric secretion but stimulate pancreatic secretion and mucous secretion in the intestines.

Taxonomic Tree Top of page Domain: More leaf of L. The leaf residue and stem interface were also obtained as fractions. Bioactivity effects of Lonchocarpus cyanescens have been demonstrated in its anti-inflammatory, anti-arthritic and its relief on ulcer.

Leaves are used as laxative. See images of our work on Flickr. The distribution in this summary table is lonchoarpus on all the information available. The antipsychotic effects of the extracts were assessed using the amphetamine animal model of psychosis in rats. Above mentioned metabolites may be responsible for literature acclaimed bio-activities L.

Visit our blog on Blogspot. Melting points were measured on a Gallenkamp melting point apparatus. The presence of these secondary metabolites was confirmed by thin-layer chromatography.

More plant samples for extractions were obtained from a farmland in the University of Ibadan Campus, Nigeria and identified by Dr. 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.

It has some additional pharmacological properties including antiviral, antifungal, anti-protozoal, and antibacterial activities. Other traditional uses include the treatment of yaws, leprosy and skin diseases.


Yoruba indigo (Philenoptera cyanescens syn. Lonchocarpus cyanescens)

Phytochemical analyses of the leaf ethylacetate extract yielded lonchofarpus triterpenoids [1 and 2] see Table 5. 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. The ethylacetate fraction 2 g was chromatographed on silica gel column eluting with increasing gradient of n-hexane: The plant has alternate leaves, flat fruits which are 1 – 5 seeded, oblong pod pointed at both ends []. Chemical composition of the essential oil of Lonchocarpus cyanescens stem.

Preliminary phytochemical screening showed the presence of alkaloids, anthraquinones, cardiac glycosides, cyanogenetic glycosides, flavonoids, saponins, steroids and tannins in the leaves of LC. Their investigation revealed that linolenic and oleic acids are its cyanexcens fatty acids with neutral lipids.

Results of our recent studies revealed forty plants were utilized as anti-malaria herb [1].

West African Plants

Partitioning of methanol extract from dried leaf of it with ethylacetate gave fraction, which was chromatographed using gradient elution. They are scented and are highly attractive to bees and other insects.

In Nigeria, this decoction is used to treat arthritic lonchocarpjs, venereal diseases and diarrhea. Leaf, stem and root cold methanol extracts of Lonchocarpus cyanescens were fractionated using distilled hexane to get methanol and hexane fractions. Lonchocarpus cyanescens LC is a medicinal plant commonly used in combination with other recipes in the treatment of psychotic disorders in traditional medicine.

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. Don’t need the entire report? Ground root is applied to yaws and washing with water containing powdered root helps to cure sores [5, 8,10,11]. Volatile oils from leaf L and lonchoczrpus bark B were obtained by hydro-distillation, using an all-glass apparatus adapted to British Pharmacopeia specifications and gave good yields of 0.

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

This may be the reason why glycyrrhetinic acid is said to relieve peptic ulcers [2,12,15,17]. This increases the level of prostaglandins in digestive system.

The essential oils were procured in 0.

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.

Leguminosae—Papilionoideae, Fabaceae is a deciduous scan dent shrub []. This is reported for the first time. Leaf and stem essential oils of Lonchocarpus cyanescens Benth. The extract was concentrated to give dark green solid A triterpene component of the plant has been found active against arthritis [2,12,13].
