The current research was planned to measure the comparative phytochemical and anti-oxidative potential of aqueous and methanolic extracts of two indigenously grown millet varieties of Pakistan. The locally available millet varieties, i.e. MB-87 and AF-POP flours were chemically characterized through the proximate and mineral analysis. The antioxidant extract was prepared in water and methanol. The extracts were screened for saponins, terpenoids, flavonoids and tannins; methanolic extract of MB-87 and AF-POP showed flavonoids in an average quantity (++), whilst aqueous extract had only trace (+) values. The phytochemical screening showed the presence of saponins only in the aqueous extract of both varieties. However, terpenoids and tannins were present in both methanolic and aqueous extracts. During antioxidant evaluation, millet methanolic extracts showed higher level of TPC and DPPH of MB-87 and AF-POP as 0.30±0.001 & 0.23±0.0012 mg GAE/g and 48±0.96 &46±1.09%, respectively. However, the β-carotene activity of the aqueous extract of both varieties (MB-87 and AF-POP) was recorded higher. In a nutshell, the methanolic extract of MB-87 has an appreciable atioxidant profile. Furher research should be planned to screen the important constituents of Pakistani millet varieties.

OBJECTIVES: To evaluate the Immunomodulatory, apoptosis induction and antitumor effects of aqueous and methanolic extracts of Calvatia craniiformis regarding the size of tumour mass, caspase-8 expression and apoptotic index (AI%) in mice transfected with murine hepatocellular carcinoma cell line (H22) as an experimental therapeutic system for human hepatocellular carcinoma.MATERIAL AND METHODS: Forty-eight Balb/C albino mice were transfected in legs with H22 cells. Tumour size was measured twice a week. Caspase-8 protein expression and apoptotic index determination evaluated by Immunohistochemistry.RESULTS: Tumor size significantly differed between the two groups of mice transfected with H22 cells; the first was treated with C. craniiformis aqueous extract (0.3, 0.6, 1.2) mg/kg and the second group was treated with C. craniiformis methanolic extract (0.25, 0.5, 1.0) mg/kg compared with control group. The inhibitory activity of aqueous and methanolic extracts was dose and duration dependent. The size of the tumour mass was reduced up to 87.9% when treated with 1.2 mg/kg aqueous extract and 1 mg/kg for methanolic extract. Caspase-8 expression was increased in a dose-dependent manner among H22 bearing mice treated with C. craniiformis aqueous extract (0.3, 0.6, 1.2) mg/kg. At 0.3 mg/kg, the intensity of expression was strong in (33.33%) and very strong in (66.67%). While at 0.6 mg/kg and 1.2 mg/kg the intensity of expression was strong in (33.33%) and very strong in (100%) with a significant difference (P ≤ 0.001). H22 bearing mice treated with (0.25, 0.5, 1.0) mg/kg C. craniiformis methanolic extract shows increased caspase-8 expression in a dose-dependent manner. At 0.25 mg/kg, the intensity of expression was strong in (33.33%) and very strong in (66.67%). While at 0.5 mg/kg, the intensity of expression was strong in (33.33%) and very strong in (100%). At 1.0 mg/kg, the intensity of expression was strong in (16.67%) and very strong in (83.33%) with significant difference (P ≤ 0.001). AI% of H22 bearing mice treated with C. craniiformis aqueous and methanolic extracts were significantly increased (P ≤ 0.05) compared with the untreated control group. No significant difference was reported in AI% between aqueous and methanolic extracts treated groups.CONCLUSIONS: Extracts of C. craniiformis were highly efficient in tumour growth inhibition, causing a reduction in the tumour size clinically and increase the expression of caspase-8 gene product in tumour tissue, causing increase apoptotic index of H22 cells taken from the legs of inoculated mice leading to loss of legs due to bone necrosis. Antitumor activity of C. craniiformis aqueous, and the methanolic extract was dose and duration dependent.

Buchholzia coriacea (wonderful kola) is a medicinal plant that has been used worldwide as an alternative medication to promote human health. Comparative nephroprotective effects of crude seed powder, aqueous and methanolic extracts of B. coriacea in hepatotoxic rats was investigated for 56 days. The crude powder (BCCP), aqueous extract (BCAE) and methanolic extract (BCME) significantly reduced (p<0.05) the levels of creatinine and uric acid and decreased minimally throughout the treatment periods. Total protein increased significantly (p<0.05). Significant decrease (p<0.05) were observed with 200 mg/kg BCAE and BCCP respectively in urea and BUN levels. Noticeable nephroprotective effects may be attributed to the presence of phytochemicals like flavonoids and tannins which act as antioxidants. This study has demonstrated that B. coriacea crude seed powder, methanolic and aqueous extracts caused no adverse effect on the rat kidney and may be recommended for the management of nephrotoxicity Dhaka Univ.

Staphylococcus aureus is a ubiquitous bacteria that causes a serious health problem because of its multi-resistance to antibiotics. The aimed of this study was to evaluate the antibacterial activity of P. kotschyi root against S. aureus ATCC 29213 and S. aureus, a clinical strain. The phytochemical compound was sought in the extracts by standard staining tests and extractions were carried out by fractionation using solvents depletion method with increasing polarity. The method of dilution in liquid medium was used for the antibacterial tests. The results showed that the aqueous extract of the bark was effective against both S. aureus with MICs of 0.39 mg.mL-1. The MICs of ethanolic extract were 0.39 and 0.78 mg.mL-1, respectively on S. aureus ATCC 29213 and S. aureus. The steles of P. kotschyi roots were less effective. The ethanolic and aqueous extracts at concentrations = 2MICs, have been respectively bacteriostatic and bactericidal effects on tested germs. The kinetics of inhibition showed that the aqueous extract of the bark at 0.78 mg.mL-1, completely destroyed the two germs respectively in 4 h and 5 h. The action of ethanolic extract at 0.78 and 1.56 mg.mL-1 occurs late against both S. aureus at 6 h and 7 h. Phytochemical screening revealed the presence of alkaloids, tannins, flavonoids, anthracenes, glycosides, saponosides and sterols, some of that may be responsible for the observed antimicrobial activity. This study proved the antibacterial activity of P. kotschyi roots that can be exploited as an antibiotic in the treatment of S. aureus infections.

Meloidogyne javanica is considered as the most damaging nematode of vegetables in Morocco. Eco-friendly bionematicides are urgently required for its control. In vitro experiments were carried out to assess the direct effect of bioproducts of Peganum harmala against M. javanica. The bioassay showed extracts to be nematotoxic. Aqueous extracts of P. harmala exhibited reversible nematostatic activity. The estimated ID50 of the most active product in methanolic extracts was 368ppm. HPLC-MS of the methanolic extract revealed that total content of major alkaloids of P. harmala was approximately 12.162±0.637mg/g. Harmine (8.514±0.521mg/g) is the dominant alkaloid. In conclusion, Peganum harmala has a reversible nematostatic activity on second stage juveniles of M. javanica. The effect of P. harmala is due to its possession of a high content of β-carboline alkaloids, which warrant further experimentation. Bioproducts from P. harmala should be exploited through formulations for management of the root knot nematode.

The phytochemical screening of Dipsacus mitis D. Don and Woodfordia fruticosa (L.) Kurz revealed the presence of bioactive secondary metabolites in both of the species but their concentrations were variable. Flavanoids and saponins were found in remarkable amount in both of the samples. The volatile compounds of both plants were extracted by Simultaneous Steam Distillation and Extraction (SDE) apparatus and analyzed by Gas Chromatography/Mass Spectrometery (GC-MS). Total 53 volatile compounds were tentatively identified from roots of Dipsacus mitis D. Don and 78 were identified from flowers of Woodfordia fruticosa (L.) Kurz. Alcohols were dominant in both the plants accounting 45% and 32% respectively. Numerous bioactive volatile compounds were detected in both herbs. The effects of increasing concentrations of the methanolic extracts on the amplitude and frequency of spontaneously contracting uterine tissues were tested. The effect of extracts on the smooth muscle strips from rat uterus showes the dramatic muscular relaxation on spontaneous contractility and was determided most effective at a concentration 6500 µg/ml of methanolic extract of Dipsacus mitis D.DOI: http://dx.doi.org/10.3126/jnpa.v26i1.6627JNPA.
