Soxhlet extraction method was used for the extraction of oil from five variety seeds of the jackfruit (Artocarpus heterophyllus, Artocarpus integrifolia, Artocarpus hircitus, Artocarpus inciscus, and Artocarpus integer), planned to explore its suitability for salutary uses with a special emphasis on its physiochemical characterization, spectrophotometric spectral analysis and evaluation of phytochemical constituents. Physiochemical properties include acid value, saponification value, iodine value, peroxide value, Reichert-Meissl value (RMV) and Polenske value were examined and compared with standard oils. Spectrophotometric analysis of oils was carried out to obtain information regarding the types, numbers, and position of chromophores and auxochrome and saturated and unsaturated compounds. Phytochemical constituent’s phenols, flavonoids, alkaloids, and tannins were determined in increasing concentration from 25 mg/ml to 100 mg/ml in five varieties of jackfruit seed oils. This inquiry concludes that the seed oils can support in the maintenance of health as the trend of the future is moving towards using seed oil as medicine in the management of various chronic...

Many herbal remedies have been employed in various medical systems for the treatment and management of different diseases. The plant Lagenaria siceraria, a plant belonging to the family Cucurbitaceae, has been used in the different system of traditional medication for the treatment of diseases and ailments of human beings. The n-hexane extract of Lagenaria siceraria was screened for antimicrobial activity against a wide range of both gram-positive and gram-negative bacteria by the disc diffusion method. The results obtained were compared with that of a standard antibiotic, kanamycin. The n-hexane extract showed significant antimicrobial activity against Escherichia coli (17.25 mm), and Salmonella typhi (17.80 mm). But there was no antimicrobial activity against Vibrio cholera, Bacillus cereus, Bacillus subtilis, and Staphylococcus aureus....

The leaf of Verbena officinalis was collected, air dried under the shed, powdered, soaked in and extracted with 80% methanol. The crude extract was tested for it’s in-vitro antibacterial activity against S. aureus and E. coli using agar disc diffusion method. Antibacterial assay was made using extract concentrations of 250 mg/ml, 500 mg/ml, and 1000 mg/ml. The extract showed a concentration-dependent zone of inhibition against the test bacteria. The strongest activity (largest zone of inhibition, 20.38 mm) was obtained at the concentration of 1000 mg/ml against S. aureus. The minimum inhibitory concentrations (MICs) of V. officinalis against S. aureus and E. coli were determined to be 0.019 mg/ml and 0.313 mg/ml respectively. Phytochemical analysis was also conducted on the powdered leaf of the plant. Seven secondary metabolites including chromophores, polyphenols, saponin, phytosterols, flavonoids, cardiac glycosides and tannins were detected from this medicinal plant. The observed antibacterial activity could be attributed to the presence of these secondary metabolites which have been associated with varying degrees of antibacterial activities. In conclusion,...

Garlic is one of the earliest well known medicinal plants, which used to cure different disease in a human being. It used to fight infections, prevent cancer, antidiabetic, hepatoprotective, anthelmintic, anti- antioxidant, and wound healing. Based on the above important of garlic, this study was conducted to investigate the antibacterial activity of garlic extracts (ethanol, acetone and aqueous extracts) against bacterial strains. The antibacterial activity of garlic was tested against gram-positive Bacillus subtitles and gram-negative E. coli bacterial strains by using agar well diffusion method. The results reveal that garlic extract shows inhibitory activity against gram-positive bacteria Bacillus subtilis and gram-negative E. coli bacterial strains. The maximum zone of inhibitions observed against Bacillus subtilis with the combination (32 mm), aqueous (30 mm), ethanol (26 mm), and acetone (22 mm) extracts, respectively. Minimum inhibition zone was observed in all extracts against Gram-negative Bacteria (E. coli), i.e. combination (21 mm), aqueous (16 mm), ethanol (14 mm), and acetone (12 mm). The results showed that B. subtilus is more susceptible to garlic...

Infertility is one of the most extremely tragic all over the world. Despite recent advances in the treatment of male infertility, the problem has not been satisfactorily tackled. The male infertility is mainly due to an inadequate number of spermatozoa in the semen, the failure of the spermatozoa to move with sufficient vigor towards their goal. Herbal medicines have been broadly used in developed countries hence they are natural and comparatively safe. They contain plant materials as their pharmacologically active components. The aim of the study is to evaluate the acute and sub-acute toxicity of the spermatogenic Siddha drug Magizhampattai Chooranam (MPC). For acute studies, different doses of MPC were administered orally to rats once daily for one week. For sub-acute studies, different doses of IC were administered orally to rats once daily for 28 days in various doses at 250, 500, 1000 mg/kg of body weight. Detailed hematological, biochemical, necropsy and Histopathological evaluation of organs were performed for all animals. Histopathological analysis revealed that Spleen, Testes, Pancreas, Lung,...
