The present study was carried out to investigate the phytochemical screening, the acute toxicity, in vivo anti-inflammatory and anti-diarrheal activities of the Zizyphus lotus (Z lotus) leaf’s aqueous extract. The extract was subjected to phytochemical analysis, acute toxicity study, anti-inflammatory evaluation using carrageenan induced paw edema and the anti-diarrheal activity was assessed by the castor oil induced diarrhea inhibition method in laboratory rats. The preliminary phytochemical screening of the extract revealed the presence of saponins, flavonoids, and triterpenoids. The extract at the doses used caused a significant (P< 0.05) reduction in the wet feces dumped by the rat with the castor oil-induced diarrhea, and decreased the distance travelled by the charcoal meal. The results showed that the extract of Zizyphus lotus has a significant antidiarrheal and anti-inflammatory activity which supports its use in traditional herbal medicine practice.

In Africa, medicinal plants are commonly used to treat malaria and other diseased conditions. The ethanolic leaf and twig extract of Faurea speciosa has been shown to possess promising antiplasmodial properties. This present study was aimed at investigating its antiplasmodial effect in vivo. Qualitative phytochemical screening was carried out on the plant samples using standard methods. The antiplasmodial effect against early infection, curative effect against established infection, and prophylactic effect against residual infection were studied in vivo in Plasmodium berghei-infected mice while the carrageenan-induced edema model in chicks was used for anti-inflammatory tests. The phosphomolybdenum and DPPH radical scavenging assays were used in the evaluation of antioxidant potential. Acute toxicity of the extract was evaluated using the Organization for Economic Cooperation and Development (OECD) guidelines. Phytochemical screening of plant samples revealed the presence of flavonoids, coumarins, tannins, saponins, and glycosides. Faurea speciosa leaf and twig extract exhibited significant antiplasmodial activities in the mouse model with parasite suppression rates of 66.63%, 71.70%, and 56.93% in the suppressive, curative, and prophylactic tests, respectively. A 55.50% reduction of edema in the anti-inflammatory test indicated moderate success in reducing inflammation. The total antioxidant capacity of the extract was determined to be 65.4 mg AAE/g of extract, while in the DPPH radical scavenging assay, the IC50 value was found to be 499.4 μg/mL. With the exception of an inconsistent rise in urea level, there was no significant difference in the other biochemistry parameters in the acute toxicity studied. The median lethal dose (LD50) of the extract was over 2000 mg/kg. The results of this study show that Faurea speciosa leaf and twig extract has promising antimalarial capabilities and is fairly safe at low concentrations.

This work aims to elucidate the chemical composition of two essential oil (EO) samples obtained from the leaves of Thymus vulgaris L. ( Lamiaceae) collected in two regions of Northwestern Algeria (Tlemcen and Mostaganem) and to assess their in vivo acute toxicity and anti-inflammatory activity. Sixty-six compounds could be identified by means of simultaneous GC-FID and GC-MS, accounting for 99.3% of total thyme oil of Mostaganem (EO.TM) and 99.0% of Tlemcen (EO.TT). In both samples, thymol was the major component, amounting to 59.5% (EO.TM) and 67.3% (EO.TT) of the total oil. EO.TT proved to be acutely toxic to mice at a dose of 4500 mg/kg p.o., whereas EO.TM did not show signs of acute toxicity, even at the highest dose tested (5000 mg/kg p.o.). Both EO samples were proven to possess anti-inflammatory activities, significantly reducing carrageenan-induced paw edema in mice (after 6 hours at a dose of 400 mg/kg p.o) at 58.4% for EO.TT and 50.4% for EO.TM, respectively. In conclusion, it could be demonstrated that EOs of T. vulgaris exhibit a considerable in vivo anti-inflammatory activity at non-toxic doses.

Background: Pain and inflammation are major health problems. The adverse effect of synthetic drugs for the management of painful inflammatory conditions gives a strong motivation for researchers to develop newer drugs with a lesser side effect. Mimosa rubicaulis has been used traditionally in rheumatism, fungal infection, wound, fever, etc. Objective: The objective was to evaluate the anti-inflammatory and analgesic activity of ethanolic stem extract of M. rubicaulis in Swiss albino rats. Methods: The stem of M. rubicaulis were collected, subjected to double maceration using ethanol as a solvent. Then, swiss albino rats (n=72) were taken. An acute toxicity study was conducted using different doses of plant extract. The antiinflammatory activity (100 mg/kg, 250 mg/kg) was evaluated using the carrageenan-induced paw edema test. While, analgesic activity (100 mg/kg, 250 mg/kg) was evaluated using a hot plate and tail immersion method. The result was analyzed using a one-way Analysis of variance and post hoc analysis with the Tukey test. Results: The acute toxicity study showed that the plant is safe for use in an animal model. The extract showed antiinflammatory activity by a reduction in paw edema volume i.e. 25%, and 48%. Similarly, analgesic activity was shown by an increase in latency of paw licking and tail withdrawal by 41%, 56% (hot plate method) and 39%, and 54% (Tail immersion method), p<0.05. Conclusion: It can be concluded that ethanolic extract of Mimosa rubicaulis is safe and possesses both anti-inflammatory and analgesic activity.

Ormenis mixta L. is traditionally used for central nervous system (CNS)-related diseases. Its anti-stress properties have received attention in Moroccan traditional medicine and aromatherapy. However, no pharmacological studies have yet been undertaken on this plant in Morocco. The present study provides a preliminary phytochemical screening and psychopharmacological profile of the essential oil and aqueous extract from Ormenis mixta L. by using behavioral tests in vivo, at graded doses. The result of this research shows that Ormenis mixta L. was safe up to 2 g/kg b.w. (body weight) in the acute toxicity study, possesses potential psychostimulant effect, and has antianxiety and antidepressant-like activity. This activity profile of Ormenis mixta L. was similar to the typical psychostimulant, caffeine. The exact mechanism of action underlying this stimulant-like effect should be clarified with further detailed studies. These results explained the extensive use of Ormenis mixta L. as a traditional medicine in Morocco.

Antioxidant Effects

Oxidative stress and inflammation are interlinked processes. The aim of the study was to perform a phytochemical analysis and to evaluate the antioxidant and anti-inflammatory activities of ethanolic Mahonia aquifolium flower (MF), green fruit (MGF), and ripe fruit (MRF) extracts. Plant extract chemical composition was evaluated by HLPC. A DPPH test was used for the in vitro antioxidant activity. The in vivo antioxidant effects and the anti-inflammatory potential were tested on a rat turpentine oil-induced inflammation, by measuring serum nitric oxide (NOx) and TNF-alpha, total oxidative status (TOS), total antioxidant reactivity (TAR), oxidative stress index (OSI), 3-nitrothyrosine (3NT), malondialdehyde (MDA), and total thiols (SH). Extracts were administrated orally in three dilutions (100%, 50%, and 25%) for seven days prior to inflammation. The effects were compared to diclofenac. The HPLC polyphenol and alkaloid analysis revealed chlorogenic acid as the most abundant compound. All extracts had a good in vitro antioxidant activity, decreased NOx, TOS, and 3NT, and increased SH. TNF-alpha was reduced, and TAR increased only by MF and MGF. MDA was not influenced. Our findings suggest that M. aquifolium has anti-inflammatory and antioxidant effects that support the use in primary prevention of the inflammatory processes.

Anogeissus pendula Edgew has been reported to be used in gastric disorder even though no attempt has been made to evaluate the same. The present study was designed to evaluate the hydroalcoholic extracts of stem bark and leaves for in vivo acute antiulcer and anti-inflammatory activities. Antiulcer activity was studied by pylorus ligation induced ulcers while anti-inflammatory activities was studied by carrageenan induced paw edema. The extract of stem bark at 200 and 400 mg/kg b. w., significantly (P<0.05) reduced ulcer index whereas extracts of both stem bark and leaves significantly (P<0.001) reduced paw diameter at the fifth hour. The hydroalcholic extract of stem bark of A. pendula possesses more significant antiulcer and anti-inflammatory activity than the hydroalcholic extract of leaves may be due to the presence of higher amount of phenolic compounds.
