Different parts of Vitellaria paradoxa plant have many applications in ethno-medicine. Some of the uses of this plant include treatment of diarrhoea and other GIT disorders. In this study the antidiarrhoeal activity of the ethanol extract of Vitellaria paradoxa was evaluated using three experimental models: Castor oil-induced diarrhoea; small intestinal motility and intestinal fluid accumulation (enteropooling) models in mice. Five groups of five mice were used for each model. Group one mice received 10 ml/kg of distilled water, while groups 2, 3, and 4 received 125, 250 and 500 mg/kg of the extract orally respectively. Group 5 mice received Loperamide 5 mg/kg orally. Oral median lethal dose (LD50) of the extract was determined using OECD (2008) Guideline 425. Phytochemical studies were conducted using standard procedures. The LD50 was estimated to be greater than 5000 mg/kg body weight and there were no signs of mortality or visible signs of toxicity in all the mice treated. Phytochemical screening revealed the presence of carbohydrates, alkaloids, flavonoids, saponins, tannins, triterpenes, steroids, cardiac glycosides and anthraquinones glycosides. Extract showed a dose-dependent anti-diarrhoeal activity by reducing stool frequency and consistency. The extract at the higher doses significantly (p < 0.05) inhibited GIT motility and castor oil-induced enteropooling, comparable to that of the reference control drug Loperamide. The study showed that ethanol stem bark extract of Vitellaria paradoxa possess anti-diarrhoeal activity and thus justifies its ethno-medicinal use in the treatment of diarrhoea.

Albizia ferruginea (Guill. & Perr.) Benth bark is used in the traditional medicine as a vermifuge. This study sought to determine the anthelmintic activity of the stem bark extract of Albizia ferruginea. The powdered A. ferruginea stem bark was extracted with ethanol. Phytochemical screening was carried out on A. ferruginea ethanol extract (AFE) and then screened for its anthelmintic property against Pheretima posthuma and Haemonchus contortus using the adult motility assay. The effect of AFE and its fractions on the anthelminthic activity of mebendazole and albendazole were also determined using the adult worm (P. posthuma) motility assay. AFE showed a dose-dependent anthelmintic activity against P. posthuma and H. contortus. The least concentration of AFE (0.5 mg/mL) paralyzed and killed P. posthuma within 272.50 ± 12.42  min and 354.50 ± 5.06  min of exposure, respectively. AFE at the least test concentration (0.14 mg/mL) caused paralysis and induced death of H. contortus, after at 63.50 ± 2.98 and 254.96 ± 2.44  min of exposure, respectively. AFE extract at 0.25 and 0.125 mg/mL increased the paralytic and helminthicidal activities of albendazole. The paralytic and helminthicidal activities of mebendazole were reduced when combined with AFE (0.25 and 0.125 mg/mL). Among the three fractions obtained from AFE, the methanol fraction showed the highest anthelmintic activity. The methanol fraction at 0.5 mg/mL caused paralysis after 69.90 ± 0.15  min and death of worm after 92.53 ± 0.74  min of exposure. The petroleum ether and ethyl acetate fractions showed relatively low anthelmintic activity. Phytochemical screening of AFE revealed the presence of tannins, saponins, glycosides, alkaloids, and coumarins. The results from this study show that A. ferruginea possesses anthelmintic activity which gives credence to its folkloric use.

Aims: To study the In-vivo anti-typhoid activities of ethanol stem bark extract of Bridelia ferruginea in albino rats infected with Salmonella typhi. Study Design: Experimental design. Place and Duration of Study: Department of Microbiology, Federal University of Technology, Akure, Ondo State, Nigeria. Between January, 2019 and June, 2019. Methodology: Fresh stem bark of Bridelia ferruginea were collected, dried, powered and extracted using 70% ethanol. Twenty – seven rats of same age between 90 -120 g in weight were selected and divided into 9 groups containing three each. The infectivity dose (ID) was determined with the clinical S. typhi. After which the rats were infected and orally administered various standard doses of the B. ferruginea stem bark extract (50-5000 mg/kg) accordingly for 7 days. During the treatment period, the fecal samples were collected to monitor the ability of the extract to reduce the fecal shedding of S. typhi. Also, the rats were weighed daily to establish the effect of treatment on their metabolism. Results: Ethanol extract of B. ferruginea Stem bark at concentrations of 50 mg/ml – 100 mg/ml, didn’t produce any zone of inhibition but from 300-5000mg/ml produce zone of inhibition (ZI) at 2.00-18.33 mm (P< 0.05) on culture of clinical S. typhi isolate and on typed S. typhi isolate zones of inhibitions were seen at concentrations 50mg/ml-5000mg/ml, it produced ZI of 8.00 – 26.19 mm(P< 0.05). Minimum inhibitory concentration of the ethanol extract on the clinical S. typhiis 300mg/ml while on the typed isolate the minimum inhibitory concentration of the ethanol extract was 2600 mg/ml on ethanol extract respectively. The MBC for the two S. typhi isolates were 300 mg/ml and 1000 mg/ml respectively. The in-vivo investigation showed the ethanol extract of B. ferruginea stem bark on S. typhi colony forming units per ml (cfu/ml) of suspensions of faeces of infected rats and treated with the ethanol extract of B. ferruginea stem bark decreased significantly (P< 0.05) as the days of the treatment increased while the cfu/ml of the infected but untreated group significantly (P< 0.05) increased. There were no significant (P< 0.05) difference between weights of S. typhi un-infected, infected rats treated with Ciprofloxacin and ethanol extract of B. ferruginea stem bark but weight of the untreated group significantly (P< 0.05) decreased. Preliminary phytochemical screening of stem bark of Bridelia ferruginea ethanol extract revealed the presence of saponins, tannins, flavonoids, glycosides and terpenoid were pharmacological importance. Conclusion: The in-vivo anti- typhoid activity of stem-bark ethanol extract of Bridelia ferruginea was found to be relatively safe against Salmonella typhi.

Objective: The objective of this work was to validate the traditional claim of the use of the stem bark of Berlinia grandiflora in treating liver problems by investigating the effect of its ethanol stem bark extract on maker liver enzymes in vivo.Methods: Groups of Wistar albino rats (6 in each group) were daily treated with CCl4 (2 ml/kg b.w., diluted with olive oil 1:1 v/v, intravenously), followed by oral administration of ethanol stem bark extract of Berlinia grandiflora (ESBG) at doses 100, 300 and 900 mg/kg b.w. respectively, 3 h after the administration of the CCl4. Serum biochemical parameters were measured 24 h at the end of the 7-day treatment period and compared to a group intoxicated with CCl4 (2 ml/kg b.w., diluted with olive oil 1:1 v/v, intravenously) alone.Results: Treatment of rats with ESBG (at doses 100, 300 and 900 mg/kg b.w. orally) reduced the impact of CCl4-induced hepatotoxicity on liver maker enzymes Alanine aminotransferase (ALT), Aspartate aminotransferase (AST), Alkaline phosphatase (ALP) and total bilirubin (TB), with the 900 mg/kg b.w. showing a significant reduction (p<0.05) compared to the group intoxicated with CCl4. The extract reversed the impact of the CCl4-induced hepatotoxicity by increasing the concentration of the serum Total protein (TP) and albumin (ALB), with the 900 mg/kg b.w. dose showing a significant increment (p<0.05) compared to the group intoxicated with the CCl4.Conclusion: The investigation of the effect of Berlinia grandiflora on CCl4 induced liver damage revealed that the ethanol extract of the stem bark of the plant was able to reverse the hepatotoxicity, with the 900 mg/kg b.w. dose showing a significant activity.

We investigated the antioxidant and anti-inflammatory effects of a 70% v/v ethanol extract of the stem bark of Antrocaryon micraster on murine models of carrageenan-induced pleurisy and paw oedema. Rat pleural fluid was analysed for volume, protein content, and leucocytes, while lung histology was assessed for damage. Lung tissue homogenates were assayed for glutathione (GSH), superoxide dismutase (SOD), catalase (CAT), malondialdehyde (MDA), and myeloperoxidase (MPO). Phytochemical analysis was carried out on the stem bark. Acute toxicity studies were conducted in rats. In the pleurisy model the extract (30–300 mg/kg) significantly reduced the volume and amount of proteins and leucocytes in the exudate and also protected against lung injury. Tissue level of GSH and SOD and CAT expression were increased while MDA level and MPO activity were reduced. The peak and total oedema responses were significantly suppressed when given both preemptively and curatively in the mice paw oedema test. Saponins, alkaloids, triterpenoids, and tannins were present in the stem bark. A. micraster extract exhibited no apparent acute toxicity. We conclude that the ethanolic stem-bark extract of A. micraster has antioxidant action and exhibits significant anti-inflammatory activity through suppression of pleurisy and paw oedema induced with carrageenan.

Objective: Knema attenuata (Myristicaceae), popularly known as “wild nutmeg,” is an endemic tree species from Western Ghats, which has been used in folk medicine. Conventionally, the stem bark of K. attenuata is used for treating inflammatory conditions without any scientific information available for the same. The present study was undertaken to evaluate the anti-inflammatory activity of the ethanolic stem bark extract (ESBE) of K. attenuata using in vivo and in vitro screening models. Methods: The ethanolic extract of stem bark was prepared by soxhlation, and its cytotoxicity in RAW 264.7 cell line was assessed using MTT assay method. In vivo anti-inflammatory effect of extract was estimated in rats using carrageenan-induced paw edema model and cotton pellet-induced granuloma model. The in vitro anti-inflammatory activity of the extract was evaluated by cyclooxygenase and lipoxygenase inhibition assay, estimation of myeloperoxidase activity, and determination of cellular nitrite levels in lipopolysaccharide-stimulated RAW 264.7 macrophage cells. Results: Toxic symptoms were not observed for the ESBE. The extract demonstrated significant anti-inflammatory activity in both in vivo and in vitro models. The anti-inflammatory action exhibited by the extract was a result of the inhibition of leukocyte migration and nitric oxide pathway and partially by inhibition of mediators such as prostaglandins and leukotrienes. Conclusion: Findings from the study provide the evidence for the popular use of stem bark extract of K. attenuata as a potential anti-inflammatory agent.

Background: Smilax zeylanica Linn (Smilaceae) is a woody climbing shrub native to Asia's tropical and subtropical highlands. Traditionally, this plant has been widely used to cure a variety of ailments. Smilax zeylanica stem bark was extracted with ethanol to test its antinociceptive and anti-inflammatory properties. Objective: To study the antinociceptive and anti-inflammatory activities of ethanolic stem bark extract of Smilax zeylanica Linn. in Wistar rats. Methods: The antinociceptive activity has been assessed in mice by formalin-induced paw licking, Eddy’s hot-plate, and acetic-acid induced abdominal stretching models. Carrageenan-induced paw oedema in rats has been conducted to explore the anti-inflammatory activity. Tween 80 (10ml/kg, p.o) was given to the control group, test drug group received ethanol extract of Smilax zeylanica (EESZ) orally at doses of 200 and 400 mg/kg, and standard drugs morphine (5 mg/kg, s.c), diclofenac sodium (10 mg/kg, i.p) were injected to the standard drug group. Results: Oral administration of ethanolic extract of Smilax zeylanica (EESZ) at test doses (200 and 400 mg/kg), produced a significant decrease of the paw licking time for 2 phases (neurogenic and inflammatory) in the formalin test, upsurge of the reaction time in Eddy’s hot plate test, and significantly decreased the abdominal stretching in the acetic acid-induced  writhes test. Ethanol extract of Smilax zeylanica significantly decreased the carrageenan-induced paw oedema. Conclusion: The ethanol extract of Smilax zeylanica possesses antinociceptive, anti-inflammatory activity, probably involving central and peripheral pathways
