Annona muricata L. (Soursop or Graviola) is a naturally occurring plant seen in Southern part of Africa, traditionally used in Benin to treat various diseases. The present study aimed to investigate phytochemical composition and antioxidant, anti-inflammatory activities of A. muricata leaves extracts. The secondary metabolites of ethanolic and hemi-ethanolic extracts were analysed by HPLC method. The DPPH and FRAP methods were used to evaluate the antioxidant activity. Inhibition of albumin denaturation method was used to evaluate anti-inflammatory activity of the tested extracts of which larval cytotoxicity was studied. The major identified compounds were gallic acid, chlorogenic acid, cafeic acid, tannic acid, ferrulic acid, Rutin. Ascorbic acid exhibited the highest inhibition percentage (83.33% ± 0.50%) of DPPH radical with the lowest IC50 (45.1 ± 0.28 μg/ml). The inhibition of the ferric ion Fe3+ varied (p = 0.0013) according to the extracts type. IC50 values of ferric ion inhibition range from 119.5 ± 3.10 to 250.8 ± 2.13 μg/ml respectively for A. muricataa. st

Over the la.t deca.e, the ra.id growth in tra.fic a.d the number of network devices ha. implicitly led to a. increa.e in network energy consumption. In this context, a.new pa.a.igm ha. emerged, Softwa.e-Defined Networking (SDN), which is a. emerging technique tha. sepa.a.es the control pla.e a.d the da.a.pla.e of the deployed network, ena.ling centra.ized control of the network, while offering flexibility in da.a.center network ma.a.ement. Some resea.ch work is moving in the direction of optimizing the energy consumption of SD-DCN, but still does not gua.a.tee good performa.ce a.d qua.ity of service for SDN networks. To solve this problem, we propose a.new ma.hema.ica. model ba.ed on the principle of combina.oria. optimiza.ion to dyna.ica.ly solve the problem of a.tiva.ing a.d dea.tiva.ing switches a.d unused links tha. consume energy in SDN networks while gua.a.teeing qua.ity of service (QoS) a.d ensuring loa. ba.a.cing in the network.

Onions a.e a.horticultura. crop of grea. economic, dieta.y a.d medicina. importa.ce, a.d a.e highly prized by the Ivoria. popula.ion.
