Introduction. The stem bark of Ficus thonningii is used by Ethiopian traditional healers and the community for the treatment of peptic ulcer disease. Thus, the current study was aimed at evaluating the antiulcer effect of hydro-methanol extract and solvent fractions of F. thonningii. Methods. The stem bark of F. thonningii was collected and shed dried. Then, the stem bark was extracted by 80% hydro-methanol solvents and dried. The part of the dried hydro-methanol extract was further fractionated with n-hexane, chloroform, and distilled water. Dose-dependent pylorus ligation, curative indomethacin-induced, and time-dependent ethanol-induced ulcer models were evaluated for the hydro-methanol extract and solvent fractions. Statistical analysis was done by using the Statistical Package for the Social Sciences (SPSS) version 24. The analyses were carried out using one-way analysis of variance (ANOVA), followed by Tukey’s multiple comparison tests. The result was considered significant when p < 0.05 . Results. The extract of F. thonningii showed a significant ( p < 0.001 ) reduction in total acidity at all the tested doses (100, 200, and 400 mg/kg). All the tested doses of the hydro-methanol extract significantly reduced the gastric volume as compared to the vehicle (NC) ( p < 0.01 ). The gastric pH was significantly ( p < 0.05 ) increased by 200 and 400 mg/kg. Similarly, 200 mg/kg and 400 mg/kg significantly ( p < 0.05 ) lowered gastric ulceration as compared to the NC. The hydro-methanol extract and aqueous fractions of F. thonningii at 200 mg/kg showed significant ( p < 0.05 ) reduction in the ulcer index on a repeated dose of the hydro-methanol and solvent fractions. Ulcer healing effect on indomethacin-induced ulcer was not significant ( p > 0.05 ) for all tested doses of the hydro-methanol extract. Conclusion. The study demonstrated that the stem bark of F. thonningii has a potential antiulcer activity that might be due to antisecretory or cytoprotective effects.

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.

Tectona grandis L. f. (Lamiaceae) is famous for timber production and has been used in traditional medicine for treating bronchitis, liver-related  roubles, urinary discharge amongst other diseases. Methanol extract of  the stem bark was investigated for in vivo antiophidian assay against Bitis arietans and Naja nigricollis. Also, the extract and chromatographic fractions were subjected to cytotoxicity tests using tadpole model and  antiarthritic assay by proteinase inhibition. Chromatography of crude methanol extract afforded three highly polar vacuum liquid chromatography (VLC) fractions (BVLC-1, BVLC-2 and BVLC-3). BVLC-2 further gave four semi-pure uncharacterized isolates (I, II, III, IV). Only BVLC-2 and BVLC-3 were cytotoxic at 10 - 80 mg/ml, with BVLC-3 being most potent (100% mortality, LC50 40 mg/ml). Concentration-dependent proteinase enzyme inhibition (24 - 71%) at 200 - 1000 μg/ml of BVLC-2 was observed, and this was less (IC50 659.24 μg/ml) than the activity of the standard drug, acetyl salicylic acid. However, neutralization of B. arietans and N. nigricollis snake venoms using methanol extract was not dose-dependent, but the extract atthe least dose, 50 mg/kg offered better protection (75%) on Naja nigricollis envenomed-mice in 48 h. Its activity was comparable to that of the positive antivenin tested at 0.2 mg/kg. These findings justify the folkloric use of T. grandis in the treatment of snake bites, arthritic conditions, and oxidative stress-induced diseases. Keywords: Tectona grandis, methanol extract, anti-snake venom activity, tadpole cytotoxicity, anti-arthritic activity

Peptic ulcer is a condition which results from an imbalance between offensive and defensive factors of gastrointestinal system. The investigation was designed to evaluate the antiulcer activity of Symplocos racemosa whole plant methanol extract (MESR) in rat model of indomethacininduced gastric ulceration. The total acidity, gastric volume, pH and free acidity were measured to determine the anti-ulcer activity of MESR. Pretreatment with MESR (125-500 mg/kg) markedly reduced the indomethacin-induced increase in gastric ulcer index and score. These results revealed that antisecretory effects MESR were responsible for antiulcer activity of MESR.

There is an increasing need for innovative drug and prophylaxis discovery against malaria. The aim of the present study was to testin vivoantiplasmodial activity ofCroton macrostachyusH. (Euphorbiaceae) stem bark extracts from Kenyan folkloric medicine. Inbred Balb/c mice were inoculated with erythrocytes parasitized withPlasmodium berghei(ANKA). Different doses (500, 250, and 100 mg/kg) ofC. macrostachyusethyl acetate, methanol, aqueous, and isobutanol extracts were administrated either after inoculation (Peters’ 4-day suppressive test) or before inoculation (chemoprotective test) of the parasitized erythrocytes. All the extracts showed significant suppression of parasitemia compared to control (p<0.001): for the ethyl acetate extract in the range of 58–82%, for the methanol extract in the range of 27–68%, for the aqueous extract in the range of 24–72%, and for the isobutanol extract in the range of 61–80%. Chemoprotective effect was significant (p<0.001) and the suppression caused by the ethyl acetate extract was between 74 and 100%, by the methanol extract between 57 and 83%, and by the isobutanol extract between 86–92%. The study showed that it is possible to inhibit the growth of the parasites by various stem bark extracts ofC. macrostachyusin Balb/c mice supporting the folkloric use of the plant against malaria.

Abstract The harmful effects that accompany the use of orthodox antioxidant medicine have necessitated the hunt for inherent antioxidants from plants extracts. In the present study, the in vivo antioxidant and hepato-protective activities of Vitex doniana against carbon tetrachloride (CCl4) induced liver damage in albino rats were investigated. The hepato-protective activities of the methanol extract of Vitex doniana stem bark were compared with Silymarin, a known hepatoprotective drug. Twenty-five (25) male albino adult rats were grouped into five (5) each. Group 1 and 2 was used as the normal and negative control respectively. Group 3-5 were treated with 200 mg/kg, 400 mg/kg methanol extract of Vitex doniana stem bark and 100 mg/kg Silymarin respectively. Results indicated that elevated levels of serum ALT, AST and ALB, and reduced serum SOD, GST and CAT in CCl4-hepatotoxic rats was an evidence of impairment in liver function. Administration of methanol extract of Vitex doniana stem bark (200 and 400 mg/kg body weight) and standard control drug Silymarin (100 mg/kg) have no significant (P>0.05) effect on CCl4- induced elevations of the ALT and AST levels while the reduction in albumin concentration, total proteins, SOD, GST and CAT due to CCl4 was reversed. In conclusion, Vitex doniana exhibited significant antioxidant and hepatoprotective properties in CCL4 induced liver damage in rat, and thus could be used and incorporated in the development of new and effective antioxidant drugs.

Anthocleista vogelii (Loganiaceae) PLANCH. is used in Cameroonian ethnomedicine for the treatment of stomach ache and for curing fever and is used as purgative. Further investigations have shown that the stem bark of this plant possesses potent antiulcer properties. We have investigated the cytoprotective and antisecretory actions of 1-hydroxy-3,7,8-trimethoxyxanthone (AV), the xanthone obtained from the methanol extract of the stem bark. Oral administration of AV at the doses of 1, 2, and 5 mg/kg prevented in a dose-dependent manner ulcers induced by HCl/ethanol (60.90 to 93.22%), Indometacin (46.86 to 89.68%), and pylorus ligation (0.00 to 70.69%). AV reduced pylorus-ligated gastric acid secretion from 134.17 mEq/l in the controls to 118.55, 121.50, and 96.93 mEq/l, respectively, for the 1, 2, and 5 mg/kg doses and increased mucus secretion significantly in a dose-dependent manner in all experimental models. The cytoprotective and antisecretory properties of AV could thus be due to its ability to strengthen gastric mucosal defences through enhanced gastric mucus production.
