Aims: Herbal remedies are known for their anti-inflammatory and antioxidant properties. The aim of this study was to evaluate the antioxidant activities of the aqueous extracts of the bark of the trunk of 10 medicinal plants used in traditional medicine for the management of hepatic pathologies. This is Acacia nilotica (L.) Willd. ex Delile (Fabaceae – Mimosoideae), Adansonia digitata L. (Bombacaceae), Bombax costatum Pellegr. & Vuill. (Bombacaceae), Balanites aegyptiaca (L.) Delile (Balanitaceae), Cassia sieberiana DC. (Fabaceae – Caesalpinioideae), Piliostigma reticulatum (DC.) Hochst. (Fabaceae – Caesalpinioideae) Tamarindus indica L. (Fabaceae – Caesalpinioideae), Daniellia oliveri (Rolfe) Hutch. & Dalziel (Fabaceae – Caesalpinioideae), Khaya senegalensis (Desr.) A.Juss. (Meliaceae) and Gymnosporia senegalensis (Lam.) Loes.) (Celastraceae)..
Methodology: In this study, the total phenolic and flavonoid content of the aqueous extracts of the trunk bark of 10 plants were determined and their antioxidant activities by the DPPH and FRAP methods were evaluated. The link between phenolic compounds and antioxidant activity was sought through a regression curve.
Results: Acacia nilotica had the best contents of total phenolics and flavonoids respectively with 21.28 ± 0.18 g ETA / 100 g DM and 0.207 ± 0.003 g EQ / 100 g DM. For the evaluation of antioxidant activity, Acacia nilotica also gave the best activities by the DPPH method with a percent inhibition of 1.08 ± 0.03 AAE and a reducing capacity of Fe3 + to Fe2 + of 0.107 ± 0.03 AAE. A strong correlation was found between FRAP and total phenolics (r2 = 0.9559).
Conclusion: This study shows that all the plants used for the treatment of liver pathologies had an interesting antioxidant capacity but among these 07 plants had the best activities. In-depth studies on the anti-inflammatory and even hepatoprotective activity of these extracts would justify their use in traditional medicine.

Aims: This study aimed to investigate the ameliorative efficacy of combined betel and tea tree essential oil-incorporated cream on DNCB-induced atopic dermatitis-like symptoms in BALB/c mice.
Methodology: cream formulation containing blended betel essential oil (1%) and tea tree essential oil (0.5%) was topically applied onto the dorsal skin of 2,4-dinitrochlorobenzene-sensitized BALB/c mice once a day during four weeks of assay. Phosphate-Buffered Saline (PBS) and protopic (tacrolimus 0.1%) were used as negative and positive control, respectively. All mice were subjected to the assessment of AD-like symptoms including the severity of skin lesions, frequency of scratching behavior and histological features.
Results: The blended essential oil-incorporated cream has significant effect against DNCB-induced eczematous skin lesions in BALB/c mice with the dermatitis score of 2.17 ± 0.75 (n = 6, p < 0.05) and the number of scratching behavior of 6.09 ± 1.28 (n = 6, p < 0.05) compared to negative control (7.00 ± 0.63 and 18.55 ± 1.23, n = 6, p < 0.05, respectively). Animals treated showed dose-related improvements in the histology of the skin.
Conclusion: These findings confirmed the ameliorative efficacy of betel and tea tree essential oil-incorporated cream on DNCB-induced atopic dermatitis like symptoms in BALB/c mice. However, further studies are necessary to elucidate the possible synergistic effect of blended essential oils from betel and tea tree as well as the interplaying roles of major molecules present in essential oils.

Aims: The purpose of this study was to examine the CO2 absorbent (NaOH) affected Spirulina sp. medium culture to verify growth rate, CO2 fixation ability and biomass production from S. platensis using the Zarrouk medium.
Methodology: Cyanobacterium Spirulina sp. was cultured with Zarrouk’s medium at 30±2°C, pH 9 which was obtained from the Applied Botany Section of BCSIR. Besides, to prevent precipitation, the medium without the carbon source was autoclaved for 30 min at 121°C and then the carbon source and NaOH were added. Furthermore, every 6-day intervals, the biomass c content, pH, and alkalinity were measured. The samples were obtained for the same analyses when the biomass concentration reached the blend concentration (0.5 g L-1).
Results: The first concentration was used 0.5 g/L. 47g/L (1.64 mmol/L) of absorbent. The mean increase of 2.45% for biomass generated by the assay using control (2.09 ± 0.11 g) when compared to the NaOH (2.04 ± 0.25 g) was due to the larger number of growth cycles. Besides, a larger number of growth cycles 35.4% for CO2 fixation rate increase compared to the control. The final protein (28.2 ± 4.5 % ww-1) and carbohydrate (19 ± 2.5 % ww-1) content in the biomass cultivated using NaOH was lower than normally found in the control assay (43.4 ± 2.9 % ww-1) and (11.5 ±1.2 % ww-1).
Conclusion: Recent advances in CO2 fixation and biomass production utilizing microalgae were compiled and analyzed, with an emphasis on how adding the CO2 absorbent affected the growth kinetics and biomass composition of Spirulina sp. When compared to the chemical absorbent assay, the control assay's high growth and CO2-fixation rates provide several advantages.

Exposure to drug toxicity results in stress and dysfunction of metabolizing enzymes that cause illnesses and diseases. Consumption of medicinal plant rhizomes is a regime for managing the complications. On the activities of some oxidative stress marker enzymes (catalase, glutathione, and superoxide dismutase), as well as the concentration of lipid profiles (cholesterol, triglycerides, and phospholipids) of p-hydroxyacetanilide (pPHA)-induced toxicity in rats, the effects of an aqueous extract of Curculigo pilosa (C. pilosa) rhizome were assessed. Forty rats were randomly grouped into eight groups (n = 5). The control group; aqueous extract of C. pilosa rhizome group; 750 mg/kg and 1000 mg/kg per body weight of pPHA group; the preventive groups (aqueous extract of C. pilosa rhizome and 750 mg/kg per body weight of pPHA; aqueous extract of C. pilosa rhizomes and 1000 mg/kg per body weight of pPHA); and the curative groups (750 mg/kg per body weight of pPHA and aqueous extract of C. pilosa rhizome; 1000 mg/kg body weight of pPHA and aqueous extract of C. pilosa rhizome). The oxidative stress marker enzymes and lipid profiles were analyzed spectrophotometrically in the serum, kidney, brain, and liver of the animals on the seventh and fourteenth days after the administrations. The results show that pPHA decreases the oxidative stress marker activities and the lipid profile concentrations in all the compartments, but the pre- and post-treatment with an aqueous extract of C. pilosa rhizome improved the activities of the stress marker enzymes and the lipid profiles dysfunction. The result suggests that an aqueous extract of C. pilosa rhizome has preventive and curative therapeutic potential for pPHA-induced toxicity.

Andrographis paniculata, commonly known as Nelabevu, Bhunimba, Chirayetah, Kalmegh, or Creat, is a plant with extensive traditional use in Asian medicines. Its historical application, particularly in conditions related to blood irregularities, has driven contemporary scientific investigations into its therapeutic potential. This review summarizes the diverse aspects of Andrographis paniculata's traditional uses and modern applications, covering its effectiveness in respiratory infections, hepatoprotection, cardiovascular effects, antimicrobial and anti-inflammatory activities, hypoglycemic effects, and reproductive influences. The plant's active constituents, such as andrographolide, flavonoids, and diterpenoids, contribute to its pharmacological actions. However, critical evaluation and further research are essential to confirm its clinical benefits and mechanisms of action. The extensive range of its effects and the multiple active compounds highlight the plant's significance in modern herbal medicine and warrant continued exploration.

Aims: This study investigated the effects of long term consumption of A. vogeliana leaf on the liver health, kidney function, and lipid profile of female Wistar rats. This was with a view to assessing the safety and potential health effects of the plant extract. Study Design: The study employed in vivo animal model in Wistar rats. Place and Duration of Study: Department of Biochemistry and Molecular Biology, Obafemi Awolowo University, Ile-Ife, Nigeria, between June 2019 and February 2020. Methodology: Acute oral toxicity and LD50 were determined. Animals were randomized into three groups (n = 6) and treated as follows: Group 1 (normal control; distilled water), Group 2 (250 mg/kg), and Group 3 (500 mg/kg) for 21 days. Animals were sacrificed on 22nd day and plasma was analyzed for liver-kidney biomarkers: aspartate aminotransferases (AST), alanine aminotransferases (ALT), alkaline phosphatase (ALP), total bilirubin, direct bilirubin, urea, and creatinine. Also, the lipid biomarkers (total cholesterol TC), triglyceride TG, high-density lipoprotein HDL, and low-density lipoprotein-cholesterol LDL), and atherogenic indices were determined. Results: The result showed LD50 > 2000 mg/kg. A non-significant difference was observed in ALT activity, total bilirubin, direct bilirubin, and urea levels. Significant (p<0.05) elevations in AST and ALP, and a significant decrease in creatinine were observed in the treated group, suggesting detrimental effect on the kidney health. TC, TG, and LDL were significantly high, whereas HDL was significantly low in the treated group. Similarly, significant increases in non-HDL, atherogenic coefficient (Ac), coronary risk index-1 (CRI-1), and 2 (CRI-2), were observed in the treated groups, suggesting a likelihood for cardiovascular diseases. Conclusion: The study concluded that prolonged administration of A. vogeliana leaf impacted the kidneys and induced an elevated lipid profile and a sharp decrease in HDL. Therefore, prolonged use of A. vogeliana should be discouraged.

This study compared the phytochemical constituents of the leaf with the Bark extracts of T. orientalis, using the same extraction solvents. The leaf and Bark of T. orientalis were harvested at Federal University of Technology, Akure forest, dried and pulverized into powder. Extract were prepared from the powdered plants using Methanol and N-hexane. The qualitative and quantitative phytochemical presents in the extracts were determined. The functional compounds of the leaf extract were determined by Fourier Transmission Infrared Spectrometry (FT-IR). Percentage yield of Methanol was better than N-hexane for both plant parts. The phytochemicals revealed includes: Tannins, Saponins, Flavonoids, Steroids, terpenoids and cardiac glycosides. Steroids are present in Leaf extracts but absent in Bark extract, while Saponin is only present in methanol extract of Bark of the plant. Quantitative analysis revealed that terpenoids have the highest amount with 22.90 ± 0.03 mg/g in methanol extract and 28.09 ± 0.07 mg/g in N-hexane, compared with Bark extract that has 22.22 ± 0.09 mg/g in methanol extract and 23.38 ± 0.04 mg/g in N-hexane extracts. Higher quantity of phytochemicals are present in the leaf compared with the Bark of T. orientalis The Fourier Transformed Infrared spectrometry analysis, FT-IR, unveiled the organic compounds available in the extracts, which are: aliphatic primary alcohol, secondary alcohol, aliphatic primary amine, alkane, alkene, carbon dioxide, deta-lactam, phenol, and halo compound. These results indicate that T. orientalis is promising in the choice of medicinal plant for therapeutic research.

The effects of ethanol leaf extracts of Mangifera indica and Gongronema latifolium on some haematological parameters (Haematocrit, HCT; Mean corpuscular Haemoglobin concentration, MCHC; Neutrophils, NEUT; Red cell Distribution width, RDW; and mixed blood cell count, MXD) in albino wistar rats were evaluated. Sixteen animals (185-223g) were assigned four groups of four rats each. Groups 1 and 3 were treated with 200mg/kg Mangifera indica and Gongronama latifolium respectively. Group 2 was treated with 200mg/kg of both plant leaf extracts at 50:50 dosage ratio. Group 4 was not treated and served as control. Treatment was done daily via oral route for one month. The animals were allowed free access to commercial rat mash and water throughout one month treatment. At the end of the treatment, no significant difference (P>0.05) was found in the HCT, MCHC and MXD levels in all the treatment groups when compared to the control. No significant difference (P>0.05) was also found among the treatment groups. NEUT levels in groups 1,2 and 3 animals recorded significant increase (P<0.05) when compared to the control but, no significant difference (P>0.05) was observed among the treatment groups. RDW recorded significant decrease (P<0.05) in groups 1,2 and 3 when compared to the control, but not significant different (P>0.05) was found among the treatment groups. These results implied that ethanol leaf extracts of Mangifera indica and Gongonema latifolium have no adverse effects on the haematological indices studied.
