Pterocarpus Santalinoides

The effects of methanol leaf extract of Pterocarpus santalinoides DC was investigated on acetaminophen (APAP)-induced sub-acute liver damage (hepatotoxicity) in albino rats. Forty two adultmale albino ratswere used for the study, 12 for the acute toxicity study and 30 for the sub-acute hepatotoxicity study. The 30 rats used for the sub-acute hepatotoxicity study were randomly assigned into six groups (A – F) of 5 rats each as follows: Group A – APAP+distilledwater placebo (negative control),Groups B,CandD–APAP+50, 250, and 500 mg/kg body weight (bw) Pterocarpus santalinoides methanol extract (PSME) respectively, Group E – APAP + 100 mg/kg bw silymarin (positive control), and Group F – distilled water placebo only (normal control). The APAP was given at 3000 mg/kg bw orally at the beginning of the study (day 0) and after every 72 hours for 12 days, while treatment with PSME and silymarin was done orally twice daily for 15 days. Phytochemical analysis and acute toxicity evaluation followed standard procedures. Assay of serum enzymes, total serum protein, albumin, globulin, total cholesterol and bilirubin, and liver weight percentage of body weight of the rats was done at the end of the 15-day experimental period following standard procedures. The PSME had high levels of tannins, moderate levels of flavonoids, saponins, carbohydrates and reducing sugars, and low levels of alkaloids. The LD was above 5000 mg/kg bw. Treatment with PSME at the dose of 500 mg/kg bw significantly lowered (P < 0.05) serum ALT, AST, and ALP activities, cholesterol and bilirubin levels, and liver weight percentage of body weight when compared to the negative control,while treatment at the dose of 250mg/kg bw only led to significantly lower (P<0.05) serum levels of cholesterol and bilirubin when compared to the negative control. It was concluded that treatment of acetaminophen-induced sub-acute hepatotoxicity in albino rats with 500 mg/kg bw PSME significantly protected the hepatocellular integrity and ameliorated impaired hepatic excretory function.

Ethanolic Leaf Extract

The study assessed the antiplasmodial activity of the ethanolic leaf extract of Cymbopogon citratus on chloroquine sensitive Plasmodium berghei in mice. Standard methods were used to determine the bioactive components of the leaf extract, acute toxicity test and antiplasmodial activity.  Mice obtained (of body weight 20-25 g) were housed and acclimatized for seven days at room temperature before the commencement of the experiment. A total of 16 albino mice were randomized into four groups of four mice each for acute toxicity while 35 were grouped into five groups of seven mice each for antiplasmodial activity. All the groups 1-5 were infected with P. berghei and were treated for six consecutive days with leaf extract dosage of 200, 400 and        800 mg/kg, standard antimalarial drug (chloroquine) as positive control and normal saline as negative control respectively. Phytochemical screening/ bioactive compounds of the leaf extract reveals the presence of saponins (10.3 mg/g), tannins (2.38 mg/g), flavonoids (1.87 mg/g), terpenoids (19.12 mg/g), steroids (6.21 mg/g) and glycosides (19.9 mg/g) as secondary metabolites. The leaf extract revealed decrease in body weight of the infected mice and did not show any toxicity at all dosage levels used. The antiplasmodial investigation revealed a decrease in percentage parasitaemia level in mice of extract treated groups compared with mice infected and not treated. The parasitaemia reduction was higher in 800 mg/kg than 200 mg/kg and 400 mg/kg. This significant decrease (P<0.05) in percentage parasitaemia level in the study was dose and time-dependent. The extract showed significant (p<0.05) antiplasmodial activity and could serve as possible candidates for the development of new effective drugs for the treatment of malaria.

AbstractBackgroundThe folkloric claim that Cnidoscolus aconitifolius (Chaya) could ameliorate anaemia requires scientific revalidation in anaemic models.ObjectiveThe aim of this study is to investigate the anti-anaemic effect of Cnidoscolus aconitifolius on cyclophosphamide-induced anaemia in rats.MethodsThe leaves of Cnidoscolus aconitifolius were collected, dried and extracted with ethanol. Twenty five Wistar Albino rats weighing 120–180 kg were used. Anaemia was induced in groups 2, 3, 4 and 5 with a single injection of cyclophosphamide, while group 1 served as a negative control without anemia and was treated with 0.5 mL of normal saline, Group 2 rats were treated with 100 mg/kg body weight of Cnidoscolus aconitifolius. Group 3 rats were treated with 500 mg/kg body weight of Cnidoscolus aconitifolius. Group 4 served as the positive control rats and was treated with 0.5 mL of normal saline. Group 5 which served as the standard control rats and were treated with 5 mg/kg body weight of standard drug Chemiron. The treated lasted for two weeks during which blood samples were collected from each rat for haematological analysis.ResultsThe result shows that hematological parameters were elevated in groups 2, 3 and 5 rats treated with 100 mg/kg and 500 mg/kg body weight of ethanol extract of Cnidoscolus aconitifolius and chemiron respectively.ConclusionsEthanol leaf extract of Cnidoscolus aconitifolius at a graded dose of 500 mg/kg body weight had higher ameliorative effect on the haematological parameters of cyclophosphamide-induced anemia in rats.

Abstract Objectives Madhulai Manappagu – a well-known sastric and widely prescribed Siddha herbal syrup formulation indicated for treating Veluppu Noi (Anaemia especially Iron deficiency Anaemia) has been in day today practice in Tamil Nadu for a quite longer decades. The syrup is a herbal preparation which has a sweet pleasant odour and a palatable taste, contain the juice of pomegranate (Punica granatum L.) as the main ingredient. Though the formulation is a fruit juice, the safety profile of the syrup is not established and is being marketed without toxicological evaluation. The study is aimed at ascertaining the acute and sub-acute toxicity assessment of Madhulai Manappagu in Wistar Albino rats. Methods The acute and sub-acute (28day repeated oral) toxicity studies were performed as per the guidelines mentioned in the Organization for Economic Cooperation and Development (OECD) 423 (adopted on December 2001) and TG 407 (adopted on October 2008) with slight modifications respectively. For acute toxicity study, three female rats were randomly selected as control; three female rats were randomly selected and were administered a single dose of 5,000 mg/kg body weight per oral route. For sub-acute (28day repeated oral) toxicity studies, three doses of test drug MM of 500 mg/kg/day (low dose), 750 mg/kg/day (intermittent dose) and 1,000 mg/kg/day (high dose) were selected for administration. Both sexes of Wistar Albino rats were randomized into four groups of 10 animals each (five males, five females). Group I was kept as control group. Group II, III and IV served as low, intermittent and high doses of MM respectively. Animals were observed for mortality, morbidity, body weight changes, feed and water intake. Haematology, clinical biochemistry, electrolytes, gross pathology, relative organ weight and histopathological examination were performed. Results In the acute toxicity study, rats showed no toxicological signs on behavior, gross pathology and body weight of rats when treated with a single dose of 5,000 mg/kg body weight per oral route. In the subacute (28 days repeated oral) toxicity study, rats have showed no significant changes on behavior, gross pathology, body weight, and hematological and biochemical parameters when treated with Madhulai Manappagu in three different doses. Conclusions The toxicity studies which include both acute and 28 days repeated (subacute) oral toxicity studies, revealed no observed adverse effect level (NOAEL) of Madhulai Manappagu in animals. Thus the safety of the drug in human usage was ensured.

Various parts of psidium guajava linn are used in ethnomedicine in controls and treatments of different disorders such as liver, heart, and blood related disorders [11]. This research work investigate qualitative phytochemical composition of ethanol leaf extract of psidium guajava linn and its effect on some hematological parameters in albino rats. Qualitative phytochemical analysis of the extract was performed by standard procedures. A total of 20 adult male albino rats were used, they were randomly placed into 5 groups (A, B, C, D and E) each group containing 4 rats groups A, B, C, and D were administered, via oral intubation, the extract at doses of 200, 400, 600, and 800 mg/kg body weight respectively of the extract for 7 consecutive days. Phytochemical screening shows that the extract was rich in tannins anthraquinones, and flavonoid while alkaloids, saponins, terpenes and glycoside were slightly present. There was a decrease in the average body weight, physical activities, and feed and water intake of the rats in the test groups relative to the control hemoglobin concentrate, total white blood cell and packed cell volume recorded in the groups  administered the extract were significantly (p<0.05) higher than in the control this effect on  the haemotological parameters was found to be dose dependent. The findings of this study suggest that the aqueous extract of the fruit plants may be useful in control and treatment of blood related disorders.  These useful applications may be as a result of the phytochemical present in the extract.

The resistance of malaria parasites to the current antimalarial drugs has led to the search for novel effective drugs. Betula alnoides has been traditionally used for the treatment of malaria, but the scientific evidence to substantiate this claim is still lacking. Therefore, the present study aimed at evaluating the antimalarial activity and toxicity of an aqueous stem extract of B. alnoides in a mouse model. The in vivo antimalarial activity of an aqueous stem extract of B. alnoides was determined by a 4-day suppressive test in mice infected with chloroquine-sensitive Plasmodium berghei ANKA. The B. alnoides extract was administered orally at different doses of 200, 400, and 600 mg/kg body weight. The levels of parasitaemia, survival time, body weight change, and food and water consumption of the mice were determined. The acute toxicity of the extract was assessed in the mice for 14 days after the administration of a single oral dose of 5000 mg/kg. An aqueous stem extract of B. alnoides exhibited a significant dose-dependent reduction of parasitaemia in P. berghei-infected mice at all dose levels compared to the reduction in the negative control. Extract doses of 200, 400, and 600 mg/kg body weight suppressed the levels of parasitaemia by 46.90, 58.39, and 71.26%, respectively. The extract also significantly prolonged the survival times of the P. berghei-infected mice compared to the survival times of the negative control mice. In addition, at all dose levels, the extract prevented body weight loss in P. berghei-infected mice. For the acute toxicity, there were no significant alterations in the biochemical parameters and in the histopathology. In conclusion, the aqueous stem extract of B. alnoides possesses antimalarial properties. A single oral dose of 5000 mg/kg body weight had no significant toxic effects on the function and structure of the kidneys and liver. These results support its use in traditional medicine for the treatment of malaria.

The therapeutic utilization of plants for managing several diseases by people of all continents, especially Africa, is as old as tradition. The objective of this study was to evaluate the potentials of aqueous ethanolic leaf extract of Psidium guajava on male reproductive parameters. Twenty-four male Albino rats were randomly assigned into four groups of six rats per group. Rats in the control group were administered Tween 20®. Rats in groups 2, 3, and 4 were administered Psidium guajava aqueous ethanolic leaf extract orally at the doses of 100, 200, and 400 mg/kg body weight, respectively, once daily for 60 days. The body weights of the rats were determined at the beginning and end of the experiment. Sperm parameters and some reproductive organs weight of each rat was also determined, some organs were collected for histopathology. Assay for follicle-stimulating hormone, luteinizing hormone, and testosterone was done using Enzyme-Linked Immunosorbent methods. Some reproductive organs were collected for histopathological analyses. The results showed a dose-dependent increase (p<0.05) in the weight of male reproductive organs, sperm parameters, and hormones. The extract significantly increased (P < 0.05) serum testosterone in the group treated 400 mg/kg body weight when treated groups were compared with control. Furthermore, the results of FSH and LH revealed a significant (p < 0.05) increase when the treated groups were compared with the control. The histopathological analysis did not reveal any form of damage to the architectural integrity of the testis. However, there was degenerating germinal epithelium in the group administered 400 mg/kg of the aqueous ethanolic leaf extract of P. guajava. Conclusion: aqueous ethanolic extract of P. guajava has positive effects on male reproductive parameters.

Aim: The study determines the GC-MS and the anti-malarial activity of methanolic leaf extract of Carica papaya in Swiss mice infected with Plasmodium berghei NK65. Study Design: The experimental study lasted for five weeks. Place of Study: Department of Chemical Sciences (Biochemistry Unit) and animal House unit in Department of Biological Sciences (Environmental Biology Unit), School of Pure and Applied Sciences, Lagos State Polytechnic, Ikorodu, Lagos, Nigeria. Study Design and Methodology: AAS, GC-MS and phytochemical analyses were determined in the plant extract using standard procedures. Thirty-six Swiss mice of both sexes (26–32g) were divided into six groups of six mice each. Group A (normal control) was untreated and uninfected. Groups B–F were intraperitoneally inoculated with P. berghei NK65, while group B (disease control) was untreated-infected group, group C and D (standard drugs) received standard drugs, chloroquine (10 mg/kg B.WT) and artesunate (10 mg/kg B.WT); groups E and F received methanolic leaf extract of C. papaya at 400 and 600 mg/kg B.WT respectively. WBC, HCT and HGB were determined in the whole blood using BC-3200 Auto Hematology Analyzer. MDA, TP, SOD % inhibition, SOD unit, CAT and GSH were all determined in the liver homogenate using standard procedures. Results: The AAS analysis shows that the extract contains minerals like: potassium, calcium, magnesium, iron and sodium. Twenty-six compounds were identified to be present in the extract using GC-MS analysis. The active compounds with their retention time, molecular weight, molecular formula, peak area and activities were predicted. The three major prevailing compounds and their percentage abundance are: squalene (27.28%), neophytadiene (12.71%) and phytol (10.16%) respectively. The phytochemical analysis indicates the presence of tannins, saponins, alkaloids, phenolic compounds etc. The C. papaya extract caused 56.76% and 75.53%  significant (P<0.05) reduction in parasitemia at 400 and 600 mg/kg body weight respectively while chloroquine exerted 92.86% and artesunate exerted 90.67% reduction at 10 mg/kg body weight respectively carried out during  curative test. The extract significantly (P<0.05) reduced WBC count and increase HGB and HCT concentration in the treated mice compared to the infected untreated mice. There were significant (p<0.05) increase in the TP, SOD % inhibition, SOD unit, GSH and CAT levels in the liver homogenate of animals treated with chloroquine, artesunate and extract of C. papaya compared to the untreated mice. MDA level was significantly decreased in the malaria treated mice compared to the untreated mice. Conclusions: The study shows that methanolic leaf extract of Carica papaya possess antimalarial activity in Swiss mice infected with Plasmodium berghei NK 65.
