In vivo Antimalarial Activities of Five Ugandan Medicinal Plants on Plasmodium berghei in Mice

Aim: Medicinal plants have played an important role in the treatment of different ailments including malaria in developing countries particularly in Africa. This study has evaluated the antimalarial activities of Azadirachta indica A. Juss (Meliaceae), Cymbopogon citratus Stapf. (Poaceae), Moringa oleifera Lam. (Moringaceae), Tithonia diversifolia (Hemsl) A. Grey (Asteraceae) and Vernonia amygdalina Del. (Asteraceae) which are commonly-used for malaria treatment in Uganda. Study Design: This is an experimental laboratory report on antimalarial activities of some Ugandan medicinal plants for subsequent profiling in an herbal pharmacopoeia and eventual drug development. Place and Duration of Study: The Animal Research Facility and the Clinical and Research Laboratory, Faculty of Medicine, Mbarara University of Science and Technology, Uganda, between July 2019 and March 2020. Methodology: The antimalarial activity of the hot infusion of each leaf was evaluated on chloroquine-sensitive Plasmodium berghei ANKA-infected mice using 4-day test at 100 – 400 mg/kg with chloroquine (10 mg/kg) and artemether-lumefantrine (4 mg/kg) as positive controls; and distilled water as negative control. The observed haematological responses of the animals were determined with an automated haematometer. Results: The results showed dose-dependent activities in the animals treated with the extract of each plant leaf in varying degrees. Thus, V. amygdalina and T. diversifolia showed the highest antimalarial activities with the chemosuppression values of 75% and 66% at 400 mg/kg, respectively. The results of V. amygdalina, T. diversifolia and M. oleifera, extracts gave the lowest ED50 of 141, 195 and 231 mg/kg, respectively being significantly different from A. indica (ED50 319 mg/kg) and C. citratus (ED50 346 mg/kg) with V. amygdalina as the most potent extract among the five plant leaves. Conclusion: The observed activities of the five plants have therefore supported their folkloric uses as antimalarial remedies by the Ugandan traditional medicine practitioners with obvious potentials for drug development.

Abstract Sequestration of Plasmodium berghei ANKA-infected erythrocytes occurs in BALB/c mice as characteristic of Plasmodium falciparum infection in humans. Animals’ bile has been widely used for centuries in Traditional Chinese Medicine. Goat bile has been used in healing infectious and non-infectious diseases; however, no report on the use of goat bile against malaria infection and sequestration. The purpose of this study was to analyze the correlation between parasitemia and sequestration in the liver of P.berghei ANKA-infected BALB/c mice treated with goat bile. This research was an in vivo experimental study using the post-test control group design. The male BALB/c mice aged ± 6 weeks, body weight 20-25 g were used. The mice were divided into five groups where Group 1-3 were mice treated with goat bile 25%, 50%, and 100%, respectively. Group 4-5 were negative (sterile water) and positive controls (DHP). Parasitemia was observed daily from each mouse and the number of sequestered infected erythrocytes on the endothelium of sinusoids. The data were analyzed using t independent test. Antimalarial activity of goat bile was shown by the lower parasitemia in goat bile-treated mice compared with the negative control. The average number of sequestration was goat bile concentration-dependent manner. The higher the concentration, the lower the number of sequestration. Sequestration was correlated with parasitemia (p=0,0001). Sequestration of P.berghei ANKA-infected erythrocytes correlated with parasitemia, and was goat bile concentration-dependent manner.

Failure of the efficacy of antimalarial drugs is recognized in different classes of medicines for treating malaria, which urges the need for new drugs. This study tried to check the in vivo antimalarial activity of the root extracts of Acanthus polystachyus Delile against Plasmodium berghei–infected mice. The study revealed that the methanolic crude extract of the root of Acanthus polystachyus Delile showed significant ( P < .01) parasitemia suppressive activities in both models compared with the negative control. Parasitemia suppressive activities were 25.26%, 33.46%, and 51.48% in a 4-day suppressive test and 23.31%, 31.20%, and 43.54% in prophylaxis test at 100, 200, and 400 mg/kg of the extract, respectively, as compared to the negative control. Besides, the extract increases mean survival time significantly in all tested doses in a 4-day suppressive test, but in the prophylaxis model, only mice treated with 200 and 400 mg/kg significantly lived longer. Based on this finding, the root of Acanthus polystachyus Delile has strong antimalarial activity, which may be a good candidate for new antimalarial agents.

Background. Malaria is a major health concern in the world in general and developing countries in particular. Nowadays, the control of malaria has ended up steadily more complex due to the spread of drug-resistant parasites. Medicinal plants are the verifiable source of compelling antimalarial drugs. The present study was aimed to assess the in vivo antimalarial activity of leaf latex of A. melanacantha against Plasmodium berghei in mice. Methods. Acute oral toxicity study of the leaf latex was assessed in mice up to a dose of 2,000 mg/kg. A four-day suppressive model was utilized to investigate the antimalarial activity of the plant. Three extract doses, 100, 200, and 400 mg/kg/day, doses of the plant leaf latex, chloroquine, 10 mg/kg (positive control) and distilled water, and 10 mL/kg (negative control) were administered to mice. Percent parasitemia suppression, packed cell volume, mean survival time, body weight, and rectal body temperature were used to determine antimalarial activity. Results. Test groups treated with 100, 200, and 400 mg/kg of the latex showed a significant parasitemia suppression in dose dependent manner compared to the negative control with an IC50 of 22.63 mg/ml. Mice treated with 100, 200, and 400 mg/kg have shown parasitemia suppression of 14.86%, 29%, and 43.2%, respectively. The chemosuppression was significant ( P < 0.05 ) at all doses compared to the negative control. Similarly, mice treated with 100 mg/kg, 200 mg/kg, and 400 mg/kg have shown a significant survival time compared to the negative control. At the same time, weight loss reduction was observed within the test groups treated with 100 mg/kg and 200 mg/kg of the latex while the test groups treated with 400 mg/kg had showed almost no weight loss reduction. The latex also reversed the PCV reduction significantly ( P < 0.05 ) at 200 mg/kg and 400 mg/kg doses and prevented rectal temperature dropping significantly ( P < 0.05 ) at all doses. Conclusion. The leaf latex of A. melanacantha has shown significant antimalarial activity against P. berghei in mice supporting the genuine traditional antimalarial usage of the plant.

The objective of the present study was to investigate phytochemical components, antiplasmodial activity (in vivo) and evaluate the toxicity of two local medicinal plants, namely, Salvadora persica L. and Balanites rotundifolia (Van Tiegh.) used in Afar ethnomedicine for the treatment of malaria. In this study, phytochemical screening has been done using standard methods and the existence of antiplasmodial compounds was detected in these plant extracts. Four-day Peter’s test was used to determine parasite inhibition, PCV was determined by Wintrob’s method, and effects against loss of body weight and improvements on survival time were determined. LD50s of the crude extracts have been also done. Acute toxicity studies of the extracts were carried out in Swiss albino mice prior to antimalarial activity test. All extracts revealed no obvious acute toxicities on mice up to the highest (5000mg/kg) dose given. The crude extract was estimated to have oral median lethal dose higher than 5,000 mg/kg. With the 4-day suppressive test, both plant extracts demonstrated dose-dependent significant reduction in parasitemia level at all test doses compared to the negative control: in the extract of B. rotundifolia 500 mg/kg extract (60.59±3.25%), 350 mg/kg extract (48.1±1.4), and 200 mg/kg extract (41.33±1.1%) were found. And in case of S. Persica 500 mg/kg extract (50.6±4.01%), 350 mg/kg extract (35.85±0.89), and 200 mg/kg extract (27.69±1.14%) were found. The results of this study provide support for the traditional therapeutic value and the reported antimalarial activity.

The search for new antimalarial drugs has become an urgent requirement due to resistance to the available drugs and the lack of an effective vaccine. In this respect, the present study aimed to evaluate the antimalarial activity of kaempferol against Plasmodium berghei infection in mice as an in vivo model. Chronic toxicity and antimalarial activities of kaempferol alone and in combination with chloroquine were investigated in P. berghei ANKA infected ICR mice using standard procedures. The results showed that chronic administration of 2,000 mg/kg of kaempferol resulted in no overt signs of toxicity as well as no hepatotoxicity, nephrotoxicity, or hematotoxicity. Interestingly, kaempferol exerted significant (P < 0.05) chemosuppressive, chemoprophylactic, and curative activities in a dose-dependent manner. The highest antimalarial activity was found at a dose of 20 mg/kg which resulted in a significantly (P < 0.05) prolonged survival of infected mice. Moreover, combination treatment of chloroquine and kaempferol also presented significant (P < 0.05) antimalarial effects, although the effects were not significantly different from the chloroquine treated group. From the results of the present study, it can be concluded that kaempferol possesses acceptable antimalarial activities. However, further investigation should be undertaken on the mechanism responsible for the observed antimalarial activity.

Background. Malaria is among the leading causes of mortality and morbidity. Moreover, the emergence of resistance to antimalarial drugs is a major problem in controlling the disease. This makes the development of novel antimalarial drugs a necessity. Medicinal plants are important sources in discovering antimalarial drugs. Schinus molle is claimed for its antimalarial effect in Ethiopian folkloric medicine and endowed with in vitro antiplasmodial activity. In the present study, the in vivo antimalarial activity of the plant was investigated. Methods. Acute toxicity was carried out using a standard procedure. To screen the in vivo antimalarial potential of the S. molle against Plasmodium berghei (ANKA), a 4-day suppressive test was employed. The extracts and fractions were given to infected mice by oral gavage at 100, 200, and 400 mg/kg/day for four consecutive days. Parameters such as parasitemia were then evaluated. Results. Any sign of toxicity was not observed in the oral acute toxicity test. The crude extracts and solvent fractions exerted a significant (p<0.05) inhibition of parasite load compared to the negative control. The highest inhibition (66.91%) was exhibited by the 400 mg/kg/day dose of 80% methanolic crude extract. Among the fractions, chloroform fraction demonstrated maximal chemosuppressive effect (55.60%). Moreover, crude extracts and solvent fractions prevented body weight loss, reduction in temperature, and anemia compared to the negative control. Except the aqueous fraction, the tested plant extracts were able to significantly prolong the survival time of infected mice. Conclusion. The findings of the present study confirmed the safety and a promising in vivo antimalarial activity of S. molle, thus supporting the traditional claim and in vitro efficacy. In-depth investigations on the plant, however, are highly recommended.
