This study is aimed at analyzing the anticancer properties of papaya leaf extract, specifically the inhibition of cell proliferation and apoptotic induction through nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) and p53 pathways. Twenty-five mice (Mus musculus), aged 2 months and weighing 20–30 g, was injected with 0.5 mg dexamethasone for 7 days. The mice were then injected intracutaneously with 1 ml of HeLa cells (8 × 106 HeLa cells/microliter). The mice were divided into five groups (5 each): negative control (P1) (5% CMC-Na, sodium carboxymethyl cellulose), treatment II (225 mg/kg BW (body weight) papaya leaves methanol extract), treatment III (450 mg/kg BW), treatment IV (750 mg/kg BW), and treatment PV (2 mg alcohol anticancer drug). Papaya leaf extract treatments were applied for 2 weeks. Then, the tumor tissue was isolated for hematoxylin and eosin staining. Immunohistochemical imaging was used to detect Ki-67, caspase-3, NF-κB, and p53 expression. Further analysis was undertaken using the ImmunoRatio software program. The results indicated that administration of papaya leaf methanol extract significantly increased the expression of NF-κB and p53 at a dose of 450 mg/kg BW. Our results also showed that the mice treated with 450 mg of papaya leaf extract per kg of BW (P3) had the largest increase of caspase-3 expression compared to the negative control group. Papaya leaf ethanol extract decreased the cancer cell proliferation index and increased apoptosis of cancer cells in animal models of cervical cancer; it may also work to increase NF-kB expression and expression of the p53 gene.

This study is aimed at the extraction and chemical analysis of the essential oils of the leaves and flowers of Lavandula stoechas L growing in northeastern Algeria. The hydrodistilled oils isolated from leaves (0.75%) and flowers (0.6%) were characterized by fifty-two and sixtyfour compounds, respectively. Gas chromatography–mass spectrometry (GC-MS) analysis demonstrated that both organs revealed the presence of fenchone and camphor as the major compounds. However, the highest percentage of fenchone (52.7%) was observed in the flowers oil; whereas, the percentage of camphor (25.94%) was significantly higher in the leaves oil in comparison with its content in flowers oil (15.52%). Other predominant compounds in leaves and flowers oils were, respectively, as follows: 1.8-cineole (4.84% and 4.02%), camphene (4.55% and 3.23%), bornyl acetate (3.06% and 4.43%), α-terpinolene (1.09% and 1.45%), viridiflorol (1.51% and 1.39%), and α- pinene (0.5% and 1.5%). The quantitative and qualitative data proved that the chemical profile of both organs of Lavandula stoechas native to Algeria was approximately close. The oil chemical composition is susceptible to the influence of environmental factors (soil, climate). The biological activity (antimicrobial and antioxidant) of the two oils from Lavandula stoechas L., native to this Algerian region is under study.

L’objectif du travail est l’étude de la composition chimique de l’huile essentielle (HE) d’Origanum floribundum Munby, ainsi que l’évaluation de son activité antioxydante et antimicrobienne. L’analyse de la composition chimique réalisée par chromatographie phase gazeuse couplée à la spectrométrie de masse a permis d’identifier 27 composés représentant 99,8 % de la composition totale, dont le composant majoritaire est le p-cymène à 53,4 %. Les résultats de l’activité antimicrobienne de l’HE ont montré qu’elle présente un large spectre d’action vis-à-vis de tous les microorganismes testés, ainsi qu’un effet bactéricide et fongicide puissant. La zone d’inhibition la plus importante (50,67 ± 0,58 mm) a été observée chez Candida albicans et la plus faible chez Pseudomonas aeruginosa (13,33 ± 1,44 mm). L’activité d’inhibition du radical DPPH (2,2- diphényl-1-picrylhydrazyle) à 600, 800 et 1 000 mg/l par l’HE est comparable à l’hydroxytoluène butylé (BHT) et au tocophérol (vitamine E), antioxydants de référence, elle reste inférieure aux concentrations de 100, 200 et 400 mg/l avec une valeur IC50 de 500,71 ± 16,97 mg/l. Le pouvoir réducteur de l’HE d’origan aux concentrations (100, 200, 400, 600, 800 et 1 000 mg/l) est légèrement inférieur aux antioxydants de référence retenus pour cette étude.

This study was designed to evaluate the chemical composition and anti-inflammatory activity of the common myrtle essential oil (Myrtus communisL.). The essential oil composition ofMyrtus communisL. extracted by steam distillation was characterized by a high oxygenated monoterpene fraction (80.9%). The major components were myrtenyl acetate (38.7%), eucalyptol (12.7%), α-pinene (13.7%), and linalool (7.00%). The chemical profile of this essential oil allows us to classify it as myrtényle acétate/α-pinène chemotype, but with atypical proportions, related to the harvesting area. In the carrageenan-induced paw edema, five different groups were established and the essential oil was administered orally in three different doses. The common myrtle essential oil (100 mg/kg) was able to reduce the paw edema, with a comparable effect to that observed with Diclofenac (positive control). This is the first report to demonstrate a significant anti-inflammatory activity of Algerian common myrtle essential oil.

L’effet inhibiteur des proanthocyanidines (PACs) de type A de la canneberge sur l’adhésion d’Escherichia coli aux cellules uroépithéliales est bien documenté. Cette adhésion étant une des étapes précoces des infections urinaires (IU), la canneberge est utilisée dans la prévention de ces infections. La cannelle étant une autre source alimentaire de PACs de type A, nous avons testé son potentiel antiadhésif dans un modèle in vitro de cellules épithéliales de vessie humaine (lignée cellulaire T24). Dans ce modèle, un extrait de cannelle de Ceylan standardisé à plus de 8 % de PACs de type A2 a inhibé l’adhésion d’Escherichia coli. L’effet observé était dépendant de la dose de PACs. Les tests effectués en association avec un extrait de canneberge ont montré un effet synergique entre les deux extraits associés en certaines proportions. Ces résultats suggèrent que la cannelle pourrait être utile dans la prise en charge des IU.

The analgesic, anti-inflammatory and antihyperlipidemic activities ofKnema attenuata(Myristicaceae), one of the ingredients of ‘Ashwagandhadhi nei (medicated ghee)’ used in the treatment of spleen disorders according to the Ayurvedic herbal medicine tradition are investigated using suitable in vivo models such as hot plate method, tail immersion test, carrageenan-induced paw oedema assay and Triton X-100-induced hyperlipidemic assay. The seed and aril (a fleshy to hard structure which develops from the funicle or ovule after fertilisation and encloses all or part of the seed) extracts were used. Both the extracts showed significant dose dependent analgesic activity up to 400 mg/kg. The dose dependent ethanolic extract of aril exhibited higher latency to hot plate and tail withdrawal reflex proving its analgesic property. Anti-inflammatory activity was demonstrated after 3 h of oedema induction. The paw volume (ml) decreased from 1.36 ± 0.05 in control to 0.73 ± 0.02 and 0.78 ± 0.02 respectively in groups treated with ethanol extract of aril and seed. The extracts of seed and aril administered at a dose of 400 mg/kg lowered the serum TC (total cholesterol), TG (triglycerides), LDL (low density lipoprotein) and VLDL (very low density lipoprotein) compared to hyperlipidemic groups. A significant decrease in the atherogenic index (a strong marker to predict the risk of atherosclerosis and coronary heart disease) was observed in animals supplemented withKnema attenuatawhich suggests an athero protective/ cardio protective potential of this plant extract. We conclude that ethanolic extract ofKnema attenuatahas significantly good analgesic, anti-inflammatory and antihyperlipidemic activity. It could be a new source of natural analgesic agent and an alternative natural source of antiinflammatory and cardio protective agents.
