AbstractMan has been dependent on vegetation in different forms since antiquity. Plants and trees have been used in the form of medications since the old times. Although the use of plant parts in the form of medicine has been less than that of the plants, therefore today it is necessary to explore some such medicinal trees. Among these, one of these trees is Arjun, whose bark is described also in Ayurveda due to its divine medicinal properties in heart diseases. The present study based on the isolation and analysis of the Phyto-constituents of the stem bark extract of Terminalia arjuna member to the family Combretaceae collected from different agro-climatic zones of India. The samples were subjected to quantitative phytochemical analysis i.e., arjunolic acid, screening by implementing the standard procedure. Observation has shown the presence of arjunolic acid in the stem bark extracts in different fractions obtained by the use of various organic solvents. Therefore, the bark extracts of the chosen plants may function as a good source of components of useful drugs for cardiovascular disorders and may also be used for the preparation of other pharmaceutical products.

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.

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.

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.

The present study was designed to assess the in vivo antiinflammatory, analgesic and antipyretic effect of the dichloromethane stem bark extract of Acacia mellifera on experimental animal model at three different dose levels of 50, 100 and 150mg/kg body weight respectively. In addition, phytochemical screening of the extract was done. The inflammatory effect was evaluated by use of carragenaan-induced paw edema in mice, pain was determined using formalin-induced writhing in mice and pyrexia was determined by turpentine-induced pyrexia in rats. The activity of the herbal extract was compared to diclofenac sodium and aspirin. The phytochemical analysis showed the presence of alkaloids, cardiac glycosides, flavonoid, saponins, steroids, terpenoids, tannins and phenolics. The plant extract produced marked anti-inflammatory effect in carrageenaninduced mice paw edema assay, suppressed licking response of animals in both phases of the formalin- induced test and exhibited appreciable antipyretic effects in turpentine-induced pyrexia in rats. The study thus supports the folklore use of the plant in the treatment and management of inflammation, pain and pyrexia.
