The presence of these secondary metabolites was confirmed by thin-layer chromatography. The African whitewood Lonchocaepus 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.
When several references are cited, they may give conflicting information on the status. In Benin, leaf sap is drunk against intestinal disorders and dysentery. Above mentioned metabolites may be responsible lnchocarpus literature acclaimed bio-activities L.
Lonchocarpus cyanescens – Wikipedia
Bright green, flat pods, pointed at each end, are fully formed by July, enclosing seeds which each form a gnarled bulge in the pod. These natural products are also responsible for the taste effects utilized in flavoring .
The acid in ulcer treatment, inhibits the enzymes that metabolize the prostaglandins, PGE 2a to their inactive metabolites. 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.
It has some additional pharmacological properties including antiviral, antifungal, anti-protozoal, and antibacterial activities.
They are scented and are highly attractive to bees and other insects. 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. 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.
Chemical Compositions of Lonchocarpus cyanescens Benth.
Leguminosae—Papilionoideae, Fabaceae is a deciduous scan dent shrub . The plant has alternate leaves, flat fruits which are 1 – 5 seeded, oblong pod pointed at both ends . Lonchocarpjs 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.
Plant was authenticated at the Herbarium, Department of Botany, University of Ibadan, Ibadan, where voucher samples were deposited and signed certificate of identification was obtained [Prof Ayodele and Mr Donatus O.
Other compositions in leaf are ketone 2. Chemical composition of the essential oil of Lonchocarpus cyanescens stem. Distribution Maps Top of page You can pan and zoom the map.
Ground root is applied to yaws and washing with water containing powdered root helps to cure sores [5, 8,10,11].
Comparison between the chemical compositions of leaf and stem volatile oils. The triterpenes act against arthritis [2,11,12,15,16]. The ethylacetate fraction 2 g was chromatographed on silica gel column eluting with increasing gradient of n-hexane: The two oils contain hydrocarbons [L 6. The anti-inflammatory activity of L. Generate a print friendly version containing only the sections you need. Similar fractions as determined by TLC were pooled together giving 10 combined fractions.
This is reported for the first time. This increases the level cyanesens prostaglandins in digestive system. These prostaglandins inhibit gastric secretion but stimulate pancreatic secretion and mucous secretion in the intestines.
The essential oils were procured in 0. A decoction of leafy twigs and roots is given to women during or after childbirth and is also taken as an aphrodisiac. It also has antitussive properties, effective as expectorant, treatment of ulcer, and flavoring for masking bitter taste of drugs like quinine. In cultivation this is an advantage as it is easier to harvest. We report our studies on volatile and phytochemical metabolites of cyanescebs of them, a Fabaceae—Lonchocarpus cyanescens leaf, stem and root.
The leaf residue and stem interface were also obtained as fractions.
A triterpene component of the plant has been found active against arthritis [2,12,13]. 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.
The distribution in this summary table is based on all the information available. Please consider upgrading your browser to the latest version or installing a new browser. Each was loaded on reversed phase HPLC, and was further purified by recrystallization. Phytochemical screenings indicated extracts contain seven important classes of secondary metabolites which are saponin, tannin, steroid, terpenoid, cardiac glycoside, phlobatannins and flavonoids Table 4. Fractions were subjected to phytochemical analysis.
Taken together, these findings suggest that the extracts possess phytochemically active constituents with antipsychotic property. Each of the oils had distinct characteristic pleasant smell. Roots and stems contain compounds with proven anti-arthritic effects. They are pounded, fermented and dried in balls about 10cm across which are sold in markets to dye fabrics and tint the hair. More leaf of L. This study was designed to examine whether the aqueous and ethanolic extracts of LC possess antipsychotic property in rats.
Results of our recent studies revealed forty plants were utilized as anti-malaria herb . Classes of phytochemical compounds identified in Lonchocarpus cyanescens [fabaceae] stem, leaf and root methanol and hexane fractions.
More plant samples for extractions were obtained from a farmland in the University of Ibadan Campus, Nigeria and identified by Dr. Yoruba indigo contains indigotin, the same pigment as in Asian indigo Indigofera tinctoria but in smaller amounts.

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