Index. décimale : 540 Chimie et sciences connexes Résumé : The phytochemical and biological study concerns the aerial parts of two endemic Saharian species belonging to the polygonaceae family: Calligonum azel and Calligonum comosum and a third one belonging to the Lamiaceae family.
The object of our work focused on the valorization of the Algerian flora. For this, firstly; we carried out a phytochemical study on Calligonum azel and Calligonum comosum which concerned mainly the biologically active compounds then we tested the antioxidant, antibacterial, antifungal and anti-inflammatory properties of all the organic extracts and some isolated compounds. Secondly; we studied the chemical composition and biological activities of Thymus ciliatus essential oil.
The study of aerial parts of C. azel and C. comosum, in order to know the active compounds responsible for their biological activity, leading to purification, chromatographic identification (CC, TLC and HPLC), and characterization using the different spectroscopic methods (1D and 2D NMR, MS and UV) of twenty one pure compounds (21) in which eighteen (18) compounds were identified.
The investigation of the biological activities of the extracts of Calligonum azel and Calligonum comosum showed that the best antioxidant activity was exhibited by the Chloroform and ethyl acetate extracts of C. azel and the Chloroform extract of C. comosum. The chloroform extracts of both species showed the best antibacterial activity. Chloroform extract from C. comosum has better antifungal activity against Candida albicans ATCC 2019 and Candida parapsilosis ATCC 22019.
From the isolated compounds, three have an antioxidant and anti-inflammatory activity. These compounds were: protocatachuic ethyl ester acid, -diamino (4-hydroxy benzene) butanoic acid and tamgernanetin.
The qualitative and quantitative analysis of essential oil of T. ciliatus allows the identification of 25 compounds representing 87.18 % of the total essential oil mainly. The GC and GC-MS analysis showed that this essential oils was mainly rich of thymol (54.26%), carvacrol methyl ether (1,373 %), o-cymene (5.72 %) carvacrol (1.373%)-cymen-7-ol (17.58 %), however it was the first time that -cymen-7-ol (17.58 %) was found as main component in the essential oils of T. ciliatus.
The evaluation of the antibacterial activity was assessed by disc diffusion method against bacterial strains. The essential oil exhibited a good antibacterial activity against Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 43300 and Staphylocossus aureus.
All of our works confirms the medicinal properties of the Saharian species, and contributes to their scientific descriptions.Diplôme : Doctorat En ligne : ../theses/chimie/BEL7311.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=10926 Etude chimique et biologique des espèces Calligonum azel et Calligonum comosum (Polygonaceae) et une espèce du genre Thymus (Lamiaceae).

????? ?????? ?????? ?????????? ??????? ?????? ???????? ???? ?????"Index. décimale : 540 Chimie et sciences connexes Résumé : This present work concerns the phytochemical and biological study of three Algerian plants belonging to the Lamiaceae family : Mentha aquatica L., Stachys guyoniana de Noé and Thymus dreatensis Batt. Chromatographic separations and purifications of extracts from the aerial parts and roots of Mentha aquatica led to the isolation and identification of 1 6 compounds, including one new triterpene and 5 triterpene acids which are new for the genus.
The structures of isolated compounds were particularly established by the use of NMR 1D and 2D (1H, 13C, COSY H-H, HMQC and HMBC), high resolution mass spectrometry (ESI-MS and HR-ESI-MS) and by comparison with literature data.
GC and GC/MS analyses of T. dreatensis essential oil showed that it was mainly represented by thymol (28.1%) followed by γ-terpinene (18.7%), thymyl methyl ether (10.9%) and linalool (5.0%). This oil showed a good antioxidant activity by the bleaching of β-carotene.
5 methods were used to evaluate the antioxidant activity of Mentha aquatica and Stachys guyoniana. The latter showed a good activity with 4 methods: β-carotene, DPPH, ABTS and metal chelating whereas Mentha aquatica exhibited a moderate activity with CUPRAC and ABTS tests. Compared with the other tested extracts, the n-butanol extract of
Stachys guyoniana showed the highest anticholinesterase activity.
The two plants showed an antibacterial potential against some bacterial strains, by the use of agar diffusion method and MIC's determination.

Index. décimale : 540 Chimie et sciences connexes Résumé : The present work deals with the phytochemical study and the evaluation of the biological activity of two plants belonging to the Algerian flora Gymnocarpos decander (Caryophyllaceae) and Mentha pulegium (Lamiaceae).
The Extraction process has been done on the aerial parts of the two species previously mentioned using organic solvents with different methods followed by chromatographic separations (CC, TLC and HPLC), the outcomes of the said extraction gave 19 products of which 5 are new (2 saponins and 3 flavonol glycosides) which have been isolated from nbutanol phase of the hydroalcoholic extract of Gymnocarpos decander, and three known
compounds isolated from the ethyl acetate extract. The remaining 11 products isolated from Mentha pulegium are known flavonoids and phenolic acids.
Structural elucidation of the isolated compounds was performed by high resolution mass spectra (HRESI-MS), 1D NMR (1H, 13C) and 2D NMR (COSY, HSQC, HMBC) and comparing them with data from the literature.
The antiproliferative activity research tests of the five new products isolated from the n-butanol extract of G. decander showed that both saponins are active against Hela cell line and the results have been very promising and hence incite to effect the vivo studies to confirm its pharmacological properties.
Quantitative estimation for total polyphenols of the hydroalcoholic extract (aerial parts) of M. pulegium has shown clearly that this extract has a high content of polyphenols.
Evaluation of the biological activity carried out on this extract showed that this species had a good scavenging effect against the DPPH radical.
On the chemotaxonomic level, the results show a rich and varied composition of secondary metabolites which is matching the plants of the same family characteristics. In fact, for the Caryophyllaceae family, saponins are considered as chemotaxonomic markers. As for the Lamiaceae family, its reputation for flavonoid accumulation is well known.

Index. décimale : 540 الكيمياء و العلوم ذات العلاقة Résumé : In this work, we conducted the phytochemical study and evaluated the antibacterial and antioxidant activities of plants grown in the Eastern Algerian belonging to the Lamiaceae family : Salvia argentea var. aurasiaca (Pomel) Batt. et Trab., Stachys ocymastrum (L.) Briq. et Salvia officinalis L..
The phytochemical study of the species Salvia argentea var. aurasiaca (Pomel) Batt. et Trab resulted in the isolation of 19 compounds of which 12 were described for the first time in the plant kingdom, The isolated compounds belong to six classes of secondary metabolites:
- 12 triterpenes
- 1 saponin
- 3 flavonoids
- 1 a simple phenol derivative (new for the genus)
- 1 cinamic acid derivative
- 1 phenylpropanoid ester heteroside
The structure determination of the isolated compound was carried out by physical methods such as UV-visible spectrophotometry, the high resolution mass spectrometry with electrospray (HRESIMS), the nuclear magnetic resonance spectroscopy (NMR 1H, NMR 13C, 1H-1H COSY, HSQC, HMBC, NOESY, ROESY).
In continuation of previous works on the species Stachys ocymastrum (L.) Briq. Four flavonoids have been isolated, we’ve identified two other flavonoids from the n-butanolic extract by the use of HPLC-UV analaysis in the presence of the authentic samples.
GC and GC / MS analysis of the essential oil of Salvia officinalis L. led to the identification of 35 compounds with 3 as the major components: the α-thujone (24.52%), camphor (16.86%) and 1,8-cineole (15.92%).
The Butanolic extract of Stachys ocymastrum (L.) Briq. exhibited a good antioxidant activity by the use of the DPPH method.
The essential oil of Salvia officinalis L. especially inhibited the growth of bacterial strains namely Escherichia coli ATCC 25922, Escherichia coli (HS) and Streptococcus homeolytic and showed good antioxidant activity by β-carotene bleaching methode.Diplôme : Doctorat en sciences En ligne : ../theses/chimie/ALEK9356.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=9478 تحدید مركبات الأیض الثانوي وَ الدراسة البیولوجیة لنباتات عطریة من جنسي Salvia وَ Stachys [texte imprimé] / هشام لكحل, Auteur ; أحمد كعبوش, Directeur de thèse . - 2014 . - 245 ورقة. ; 30 سم.
