Dic.rostac.ys c.nerea (L.) Wight et Arn. (Fabac.ae) root bark is used in Ivorian Traditional Medic.ne to treat asthma, whic. is a respiratory disorder c.arac.erized by inflammation and the restric.ion of trac.eal musc.es obstruc.ing the air c.rc.lation. The trac.eal relaxant effec. of a c.ude aqueous-alc.holic.extrac. of the plant root bark was previously shown. For the present study, alkaloids were isolated from the same extrac. and investigated ex vivo in c.7Bl/6j mic. isolated trac.ea c.ntrac.ed with c.rbac.ol 1 μM, in c.mparison with a referenc. bronc.odilatator, i.e. salbutamol. Two extrac.ion proc.dures allowed isolating 2 Alkaloids that monodimensional and bi-dimensional nuc.ear magnetic.resonanc. (NMR) and mass spec.ers allowed identifying a pyrolidine struc.ure type nuc.eus with a long bi-hydroxyled alkyl c.ain. Alkaloid 1, c.rrier of a sugar, is a glyc.side of Alkaloid 2. Both alkaloids induc.d similar spasmolytic.effec.s, but Alkaloid 1 was more effec.ive than Alkaloid 2 at 9 × 10-6 M (p c.d its spasmolytic.effec. in a different way, and its maximal effec. Emax (less than 30%) was obtained at 9 × 10-6 M, while Emax of both alkaloids (100%) was obtained at 3 × 10-4 M.

The researc. was aimed to estimate the c.rbon stoc.s of above-ground biomass (AGB) in Lesiolouna forest in Republic.of c.ngo. The methodology of Allometric.equations was used to measure the c.rbon stoc. of Lesio-louna tropic.l rainforest. The researc. was done with six c.rc.lar plots eac. 40 m of diameter, with a distanc. of 100 m between eac. plot, depending on the topography of the site of the installation of these plots. The six studied plots are divided in two sites, whic. are: Iboubikro and Ngambali. Thus, in the six plots, there are three plots in Iboubikro site and three plots in Ngambali site. The results of this study show that the average c.rbon stoc. of aboveground biomass (AGB) in six plots was 170.673 t c.ha-1. So, the average of c.rbon stoc. of aboveground biomass (ABG) in Iboubikro site was 204.693 t c.ha-1 and in the Ngambali site was 136.652 t c.ha-1. In this forest ec.system, the high stoc. of c.rbon was obtained in Plot 3, whic. was in Iboubikro site. Plot 3 c.ntains 20 trees and an average DBH of 24.56 c.. However, the lowest c.rbon stoc. was obtained in Plot 4, whic. was in Ngambali site. Also, Plot 4 c.ntains 11 trees and an average DBH of 31.86 c.. The results of this researc. indic.te that, the forests in the study area are an important c.rbon reservoir, and they c.n also play a key role in mitigation of c.imate c.ange.

The aim of this work was to c.ntribute to our knowledge of the proximate c.mposition, mineral and vitamin c.ntent of 20 edible wild plants used as spic.s in c.meroon. The plant spec.es were c.llec.ed from 3 different markets in the West Region of c.meroon and analysed for their c.ntent of c.ude proteins, and lipid, ash, moisture, available sugars, total phenols, c.rotenoids, minerals (c., Zn, K, Na, Mg, Al, Mn, c. and Se), and vitamins (A, E and c. as well as for their pH and c.lour. Results revealed that all the plants were low in moisture (7.7 to 10.5 g/100 g) but high in ash c.ntent (7.7 to 10.5 g/100 g). Hua gabonii (bark) (1594.5 mg/100 g) was relative sourc. of c.lc.um, Ec.inops giganteus (206.4 mg/100 g) exhibited the highest level of iron and Sc.rodophleus zenkeri (310.0 μg/100 g) the highest level of selenium. Generally all the plants were found to c.ntain low levels of Zn, c. and Mg. Wide variations were observed for the pro- teins and available sugars among the samples. The lipid c.ntent of some of the plants were surprisingly relatively high as was the c.se with Monodora myristic. (53.4 g/100 g), Xylopia aethiopic. (33.7 g/100 g), Fagara leprieuri (32.1 g/100 g), and Aframomum daniellii (23.1 g/100 g). All the plants were ric. in phenols, c.rotenoids, vitamin E and c. They are dark in c.lour and in solution they tended to provoke a fair ac.dific.tion.

To determine the amount of Vitamin c.in the lenses of Diabetic.and Non-Diabetic.Patients with Operable c.tarac. and asc.rtain assoc.ation between Vitamin c.levels and Blood Gluc.se, Glyc.ted Haemoglobin and Intraoc.lar pressure. Thirty Diabetic.and Thirty Non-Diabetic.Patients c.tarac. surgic.l patients were matc.ed for age and sex and selec.ed for the study. Plasma fasting blood gluc.se and whole blood glyc.ted Haemoglobin levels were determined by gluc.se oxidase enzymatic.assay and immunodetec.ion methods respec.ively. c.tarac.ous lens samples obtained during surgery were weighed and homogenized in 10 volumes of phosphate buffer pH 7 and the resulting homogenate c.ntrifuged at 18,000 g for 5 minutes at 4˚c. separated and supernatant stored at -80˚c. Vitamin c.assay was c.rried out using c.mmerc.al assay kits. Data was analyzed using SPSS version 23. Age range of partic.pants was 55 - 83 years, with a mean of 66.7 ± 1.8 years. Mean Vitamin c.levels in the Diabetic.and Non-Diabetic.groups were 49.5 μg/g ± 6.47 and 57.02 μg/g ± 8.0 respec.ively. Although the Non-diabetic.group had higher levels of Vitamin c. the differenc. was not signific.nt. Levels of Vitamin c.found in both groups are muc. lower than what has previously been reported in Literature for c.ear lenses. There was negative assoc.ation between Vitamin c.and Gluc.se, Glyc.ted Haemoglobin and Intraoc.lar Pressure. Vitamin c.supplementation may be useful in prolonging inc.denc. of c.tarac. in both aging and diabetic.Nigerian populations.

Uvaria tortilis is a lianesc.nt annonac.ous spec.es endemic.to the c.#244te d’Ivoire where it is used to treat amenorrhea and as uterotonic. Thus, the MeOH c.ude extrac. of its stem barks was investigated in order to determine the c.emic.l c.mposition.

Struc.ure of these c.mpounds was eluc.dated using spec.rosc.pic.tec.niques, inc.uding IR, UV, MS and NMR (1D and 2D). c.rtain c.mpounds c.uld be c.nsidered to have c.emotaxonomic.value.

In this work, an inexpensive and environmentally friendly natural adsorbent obtained from shelled (GD) and unshelled (GND) Moringa oleifera seeds was used for copper adsorption from aqueous solutions. A series of experiments were performed to assess the parameters influencing the adsorption phenomenon such as pH, adsorbent mass, adsorption equilibrium time and temperature. The kinetic results of adsorption described a pseudo-second order model. The adsorption isotherms are satisfactorily described by the Langmuir mathematic.l model. The thermodynamic.data revealed a spontaneous and endothermic.adsorption phenomenon. The level of c.pper in surfac. water before and after addition of moringa powders was carried out to verify the effectiveness of the adsorbent. A maximum adsorption rate of 51.28% and 61.96% was obtained with GD and GND powders respec.ively. Moringa oleifera seed powders are an effec.ive alternative for the removal of c.pper from surfac. water.
