BiologieTags : Cleome arabica ssp arabica HPLC/DAD/MS phénols totaux flavonoïdes bioactivité toxicité total phenols flavonoids bioactivity toxicity assays ????????? ???????????? ?????? ????????? ????? ?????? Index. décimale : 570 Sciences de la vie. Biologie Résumé : Cleome arabica ssp arabica, a threatened desert plant, has been subjected to the phytochemical and pharmacological screening.
Hydroalcoholic extracts from different parts (leaves, seeds and roots) of C. arabica have been tested for their antioxidant, analgesic and wound healing activities, as well as their toxic potential.
Quantitative evaluation of the total phenols, flavonoids and anthocyanidins contents of the different extracts were made and completed with chromatographic HPLC/DAD/SM analysis. The obtained results revealed that leaves extract was characterized by a highly content in phenolic compounds, compared to other extracts.
Hydroalcoholic extract of the three parts of plant were marked by the presence of flavonoids, specially of flavonols type (quercetin, keampferol, and isorhamnetin).
Phenolic acids content is marked by the presence in the seeds extract of ferulic acid, para-hydroxybenzoic acid, and para-coumaric acid, and in the roots extract of tricaffeoylquinic, gallic, ferulic, and vanillic acids.
Evaluation of antioxidant effect made by the three in vitro tests (DPPH, FRAP and Phosphomolybdenum) showed a highly antioxidant activity of the leaves extract compared to those of seeds and roots. A direct correlation was found between phenol total and flavonoids contents and antioxidant activity.
The effectives doses obtained by three pain tests, namely tail flick, hot plate and acetic acid test were 291,84mg/Kg, 848,53mg/Kg and 683,52mg/Kg respectively. Analgesic activity of the aerial part of C. arabica was found to be dose- dependent. The Hydroalcoholic extract displayed on excision and thermal healing activities
wounds. The wound healing effect of C.arabica was significantly more important than that of a commercial ointment used as a positive control (Cicatryl®).
Toxicity assays (acute toxicity, and hemolytic effect) have showed that Hydroalcoholic extract of aerial part of C. arabica is safe at the maximal described doses.

Rats Hyperglycémie Diabetes type2 phytotherapy Erythreae centaurium L. rats hyperglycemia toxicity ??? ?????? ??? 2 ???????? ????????? ????????? ????? ????? ????? ??? ???? Index. décimale : 636 Sciences Vétérinaires Résumé : Diabetis type 2 is a frequent and severe disease. Its complications constitute a public health problem.
It needs drugs, food diet and medical monitoring.
Now day, in therapeutically field, in addition to conventional treatment (insulin and oral hypoglycaeming
agents) use medicinal plants as complementary treatment as well as treatment in low glycemia.
Therefore phytotherapy constitutes a good alternative or at least as a complement to classical drugs.
In popular medicine, a lot of plants -among them, the Centaurium erythreae - are used in diabetic
treatment.
The first part of this work treats literature review on diabetes, phytotherapy and Centaurium erythreae L.
The second part consists of an experimental work that contains:
- Inquiries on the use of medicinal plants in our regions (east, south-east and Algiers region); 39 species
belonging to 24 families are noted.
- A chemical experiment of the flowering stems of the plant Erythreae centaurium L. has been done;
several products were identified( flavonoids, alkaloids, steroids and tannins...).
- An experimental work on normoglycemic rats and rats submitted to hyperglycemia by oral means by
overcharge of glucose, by gavage of aqueous and butanolic extract of the Common Centaury. After
kinetic study of glycaemia between tB0 Band tB180 Bminutes by glycometery and spectrophotometer shows an
important decrease of blood glucose rates.
The hypoglycemic action of aqueous and butanolic extract was compared to that obtained
rats with hypoglycemic agent (Glibenclamide (DCI) Daonil ® (ND)
This shows the existence hypoglycemic action of Common Centaury.
- The monitoring of rats, during fifteen days after hyperglycemia shows secondary effects of aquous and
butanolic extracts of Common Centaury on liver and kidney rats’.Diplôme : Doctorat En ligne : ../theses/veterinaire/BEN5276.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=1871 Effets biologiques de la petite centaurée Erythraea centaurium (L.)
