Seven compounds in leaf made up 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. Comparison between the chemical compositions of leaf and stem volatile oils. Work is ongoing on other aspects of L. The plant is an active anti-arthritic remedy utilized with 3 other plants in Igbo tribal ethnomedicine [11].

Chemical composition of the essential oil of Lonchocarpus cyanescens leaf.

Lonchocarpus cyanescens

All parts yield indigo dye but usually only leaves and shoots are collected. The African whitewood Triplochiton scleroxylonknown as arere in Yoruba and obeche in Bini, is a large fast-growing tree, lonchodarpus 65 m ftusually with a straight trunk and buttresses up to about 8 m 26 ft high.

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. The extract was concentrated to give dark green solid See images of our work on Flickr. In Benin, leaf sap is drunk against intestinal disorders and dysentery.

GC-MS analyses of the seed oil showed phytol, sterols, beta-tocopherol and hydrocarbons are in the cyanedcens matters of the oils; while HPLC showed presence of glycolipids [monogalactosyldiacylglycerol, digalactosyldiacylglycerol, digalactosylmonoacylglycerol and monogalactosylmonoacylglycerol]. Other traditional uses include the treatment of yaws, leprosy and skin diseases.

Methanol extract 10 g was further partitioned between aqueous methanol and ethylacetate to give the ethylacetate fraction. Visit our cyanescdns on Blogspot. Oleanane derivatives and glycyrrhetinic acid are responsible for the antiinflammatory properties and relief of peptic ulcers observed in L. Bright green, flat pods, pointed at each end, are fully formed by July, enclosing seeds which each form a gnarled bulge in the pod.

In Nigeria, cyanesecns decoction is used to treat arthritic conditions, venereal diseases and diarrhea. Cynaescens plant is utilized in traditional medicine. The distribution in this summary table is based on all the information available. The effect of the extracts on spontaneous motor activity was also studied in the open field test in mice. Flowering takes place in May when upright spikes, cm long, of lilac-blue pea flowers are produced where the vine is in full light. American Journal of Plant Sciences Vol.


TLC with high Rf was used in monitoring elution. 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 study was designed to examine whether the aqueous and ethanolic extracts of LC possess antipsychotic property in rats. cyanexcens

Similar fractions as determined by TLC were pooled together giving 10 combined fractions. These natural products are also responsible for the taste effects utilized in flavoring [17]. Seven prominent compounds in leaf make up This is reported for the first time.

This paper presents details of above cyamescens which are new in literature.
