Aim: This study is aimed at evaluating the effects of the aqueous stem bark extract of Stereospermum kunthianum on CCl4-induced hepatotoxicity in rats. Methodology: Analysis of qualitative phytochemical components and antioxidant activity were carried out. Experimental rats were randomly divided into six groups of five rats each. Group 1: served as the normal control group. Group 2: was administered with CCl4 only at a dose of 3 ml/kg b.wt by single intraperitoneal administration. Group 3: served as the standard control group.   Group 4: was administered with 200 mg/kg b.wt of the aqueous stem bark extract + CCl4. Group 5: was administered with 400 mg/kg b.wt of the aqueous stem bark extract + CCl4. Group 6: was administered with 600 mg/kg b.wt of the aqueous stem bark extract+ CCl4. Results: The phytochemical analysis showed the presence of flavonoid, phenols, saponins, and terpenoid while tannins and alkaloids were absent. The antioxidant activity showed that the extract significantly (P<0.05) inhibits Ferric Reducing Antioxidant Power (FRAP) and Thiobarbituric Acid Reactive Substances (TBARS), giving high activity as the concentration of the extract increases. The elevated levels of ALT and AST coupled with Conjugated bilirubin, Total bilirubin, and total protein caused by CCl4 administration were all reduced significantly (P<0.05) by the extract in dose dependent manner. Conclusion: These findings demonstrated that stem bark extract of Stereospernmum kunthianum could be an alternative medication for liver injury.

Miliusa velutina (MV) stem bark has various medicinal uses, but its hepatoprotective effect has not yet been studied. This study investigated the antioxidant and hepatoprotective activity of the ethanol extract of MV stem bark against carbon tetrachloride (CCl4)-induced liver injury. The ethanol extract of MV stem bark was evaluated for in vitro antioxidant activity which exhibited good antioxidant activity in terms of ferric reducing-antioxidant power assay (EC50, FRAP=4.04±0.00 µg/mL), total antioxidant capacity assay (EC50, TAC=8.73±1.08 µg/mL) and 1,1-diphenyl-2-picrylhydrazyl (EC50, DPPH=9.33±0.07 µg/mL) radical scavenging assay. Mice were pretreated with CCl4 (2.5 mL/kg body wight per day) in 4 consecutive weeks. After one hour taking CCl4 by oral administration, mice were treated with the ethanol stem bark extract of MV at various concentrations of 100, 200, and 400 mg/kg body weight. The MV stem bark at the dose of 400 mg/kg body weight effectively reduced the level of alanine transaminase (38±6.78 U/L) and aspartate transaminase (AST) in serum. Besides, the MV stem bark at the dose 400 mg/kg body weight reduced the malondialdehyde (3.12±1,19 nM MDA/g tissue) level, and increased the activity of reduced glutathione (896.21±22.69 nM GSH/g tissue) in liver. The observation of the microscopic cross section of liver tissue also revealed that the mice treated with stem bark extract of MV at the dose of 200 and 400 mg/kg body weight had significantly improvement in liver tissues compared to the non-treated control group. Histological analyses of the MV-treated group exhibited reducing inflammatory process and preventing liver necrosis and fibrosis. In summary, the hepatoprotective effect of MV stem bark was seemingly associated with its antioxidant activity.

Background: Malaria is a parasitic infection that is common in the tropical and sub-tropical regions of the world. It is estimated to kill one million individuals annually. Detarium microcarpum (Fabaceae family) is used traditionally for the treatment of malaria, diabetes, hypertension, convulsions, pneumonia, leprosy, and meningitis. The purpose of this research was to evaluate the antiplasmodial potential and safety profile of the methanol extract of D. microcarpum stem bark. Methods: The extract was subjected to phytochemical screening and oral median lethal dose (LD50) estimation. Using curative, suppressive, and prophylactic experimental animal models, antiplasmodial activity was assessed in mice infected with chloroquine-sensitive Plasmodium berghei berghei. Biochemical and hematological tests were conducted in rats orally administered with the extract for 28 days. One-way analysis of variance (ANOVA) was used to analyze the data, followed by Dunnett's post hoc test. Results: Alkaloids, flavonoids, saponins, tannins, triterpenes, and glycosides were found in the extract through phytochemical analysis. When compared to the negative control group, the extract at the tested doses (200, 400, and 800 mg/kg) showed a significant (P < 0.001) curative, suppressive, and prophylactic effect and significantly (P < 0.001) prolonged the survival time of mice in the treated groups. The extract had an insignificant (P > 0.05) effect on the biochemical and hematological parameters tested. Conclusions: The results suggest that the stem bark extract of D. microcarpum at the doses tested possesses antiplasmodial activity and is relatively safe after short-term use.

Aim: The aim is to evaluate the antioxidant potentials of Eucalyptus camaldulensis methanol stem bark extract (ECMSBE) on Wister albino rats. Methodology: The phytochemical screening of ECMSBE was conducted using standard methods. A total of 36 albino rats were used for the antioxidant studies. The rats were divided into six (6) groups of six rats. Control group received distilled water orally at 2ml/kg. Oxidative stress was induced in groups 2 to group 6 CCl4 (1ml/kg, s.c) at every 72hrs for 10 days. Group 2 was untreated while groups 3 – 6 received doses of 50, 100, 150 and 200mg/kg of ECMSBE respectively. On the 11th day, the rats were sacrificed and the liver was removed and homogenised and oxidative stress parameters were determined. Results: Phytochemical analysis of ECMSBE revealed the presence of saponins, flavonoids, tannins, phenols, glycosides, steroids, terpenoids and resins. There was no significant difference (P<.05) between the CCl4 induced group and the group treated with ECMSBE (50mg/kg). However, their concentrations were significantly different from the group treated with ECMSBE (100mg/kg – 200mg/kg) when compared to the group treated with CCl4 Only. The CCl4-induced group had its vitamin A, vitamin C and vitamin E concentrations significant different (P<.05) from the groups treated with ECMSBE (100, 150 and 200mg/kg body weight). There was no significant difference (P>.05) in the levels of SOD, CAT and GPx between the group induced with CCl4 only and the group treated with ECMSBE (50mg/kg), however, it these concentrations were significantly higher (P<.05). The enzymatic antioxidants concentration in the normal control group was not significantly different (P>.05) when compared the group that was treated with ECMSBE (200mg/kg) Conclusion: The result suggest that the extract of E. camaldulensis possessed antioxidant properties which can be used as effective protecting agents against oxidative stress and other diseases.

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.

Pellacalyx axillaris or locally known as ‘membuloh’ is a mangrove species belonging to the Rhizophoraceae family. Till date, there has been only one phytochemical study found on this particular plant species and that without any documentation on its biological activities. Therefore, the present work aimed to reveal the phytoconstituents and the antioxidant activity of different crude extracts from different plant parts of P. axillaris. Experimentally, three organic solvents of different polarities i.e. n-hexane, ethyl acetate and methanol were used to prepare the crude extracts from the dried leaves, twigs and barks of P. axillaris. The preliminary phytochemical screening of this species indicated the presence of terpenoids, phenolic compounds, tannins, flavonoids, alkaloids, anthraquinone glycosides and carbohydrates. The in vitro antioxidant activity of the species evaluated by 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay, 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) radical scavenging assay, and ferric reducing antioxidant power (FRAP) suggested that the methanolic bark extract contained potential source of natural antioxidants. Further research into isolation of antioxidant compounds from this species is highly recommended.

Extracts of Alstonia boonei and Carica papaya are used in herbal medicine for the treatment of malaria. This work investigated the phytochemical, antioxidant, and antimalarial effects of hydromethanolic extracts of Alstonia boonei and Carica papaya. A four-day chemosuppressive test was conducted to assess the ability of the extracts to prevent establishment of infection. Three doses of the extracts were administered—100, 200, and 400 mg/kg bw—prior to Plasmodium berghei challenge. Change in body weight, parasitemia, packed cell volume (PCV), and mean survival time was determined. A three-day curative test was also carried out on Plasmodium berghei-infected mice to determine the effects of the plant extracts (200 mg/kg bw) on parasitemia and biochemical indices of liver and kidney functions, lipid metabolism, and oxidative stress. The study revealed that the extracts possessed phenolic compounds (34.13 ± 1.90 mg GAE/g for Alstonia boonei and 27.99 ± 1.46 mg GAE/g for Carica papaya) and flavonoids (19.47 ± 1.89 mg QE/g for Alstonia boonei and 18.24 ± 1.36 mg QE/g for Carica papaya). In vitro antioxidant activity measured as total antioxidant power, total reducing power, and DPPH radical scavenging activity showed that the extracts possessed higher antioxidant activity than the reference compounds. The outcome of the chemosuppressive test revealed that whereas Plasmodium berghei-infected mice had high parasitemia, decreased mean survival time, exhibited loss of weight, and had low PCV, treatment with the extracts reversed the effects in a concentration-dependent manner. Similarly, the curative test revealed that the extracts significantly suppressed parasitemia compared with the malaria negative control group. This was mirrored by reversal of indices of hepatic toxicity (AST, ALT, and ALP levels), nephropathy (urea and creatinine levels), oxidative stress (SOD, CAT, GPx, GSH, and lipid peroxides), and dyslipidemia (TC, HDL, and TG levels and HMG-CoA reductase activity) in infected but treated mice compared with negative control. Put together, the results of this study demonstrate that the extracts of Alstonia boonei and Carica papaya possess antimalarial properties and are able to ameliorate metabolic dysregulations that characterize Plasmodium berghei infection. The phytoconstituents in these extracts are believed to be responsible for the pharmacological activity reported in this study.

ABSTRACTBackground: Streptococcus mutans is plaque-forming initiator bacteria. Plaque on the surface base of denture can cause color changing, bad breath, inflammation, and infection  called denture stomatitis. Denture hygiene must be maintained by denture soaking in 0.2% chlorhexidine gluconate. However, 0.2% chlorhexidine gluconatethat used incessantly can cause side effects such as the changing of denture color and the fading of denture base pigmentation. The ironwood stem bark extract can be an alternative for denture cleanser material. Objectives: To analyze the effect of ironwood stem bark extract on the growth of Streptococcus mutans on heat cured type acrylic resin denture plate. Methods: True experimental laboratories research was used with post test only control group design using 9 treatment groups which are 5%, 10%, 20%, 40%, 60%, 80%, 100% concentration of ironwood stem bark extract, 0.2% chlorhexidine gluconate and aquadest. The treatment was performed with 3 times repetition resulting in 27 total samples. Antibacterial activity was measured by calculating the bacteria colony number. Results: The 5% and 10% concentration of ironwood stem bark extract were effective in reducing Streptococcus mutans with30.3 CFU/ml and 10.3 CFU/ml average colony number. The ironwood stem bark extracts with 20%, 40%, 60%, 80%, 100% concentration are effective and equivalent to 0.2% chlorhexidine gluconate against Streptococcus mutans with 0 CFU/ml average value. Conclusion: The 20%, 40%, 60%, 80%, 100% concentration of ironwood stem bark extract is equally effective as 0.2% chlorhexidine gluconatein killing Streptococcus mutans,exhibiting potential to be an alternative for denture cleanser material.Keyword: 0.2% Chlorhexidine gluconate, ironwood stem bark extract, acrylic resin denture plate heat cured type, Streptococcus mutans.
