    ANTIBACTERIAL POTENTIAL OF GLORY LILY, GLORIOSASUPERBA, LINN
    (International Research Journal of Pharmacy, 2011-03) H, Rehanabanu; N, Nagarajan
    The successive Soxhlet extract of Gloriosasuperba, L. (Liliaceae) was extracted using acetone, dichloromethane, chloroform and methanol in ascending order of the polarity. The extracts were investigated for their antibacterial activity against two Gram positive bacteria Streptococcus faecalisand Enterococcus faecalisand two Gram negative bacteria Klebsiellapneumoniaeand Proteus mirabilis by using disc diffusion method. Among the four extracts tested, acetone extract had effective antibacterial potential, followed by methanol extract at 25 and 100% concentration against Enterococcus faecalis. The acetone extract showed greater activity against Gram-positive than against Gram-negative organisms. The study confirms the antibacterial potential of Gloriosasuperbaleaves extracted using various solvents, and is therefore, a potential drug that requires further studies and development

    MYCORRHIZAL BIODIVERSITY IN SOME GRASS SPECIES OF ANAMALAI HILLS, TAMILNADU, INDIA
    (Online International Interdisciplinary Research Journal, 2014-01) H, Rehanabanu; N, Nagarajan
    Arbuscularmycorrhizal colonization in the roots and spore numbers in the rhizosphere of thirty five different grasses from Anamalai Hills, Tamilnadu, India were investigated. Percentage of fungal infection in the roots was analyzed by a staining method of Phillip and Hayman. Quantity of mycorrhizal spores was determined by employing wet-sieving and decanting technique.The results indicated that all the grasses examined during the study, exhibited the presence of arbuscularmycorrhizal association. The percentage of root colonization by AM fungi varied from 14% to 68%. Perotisindica had maximum percentage of colonization (68%). The presence of greater number of spore in soil was always associated with the incidence of abundant mycelia. Number of mycorrhizal fungus spores ranged between 172 to 475 per 100g air dried soil. A total of 26 arbuscularmycorrhizal fungal spores were isolated from the grasses represented by four genera, namely 6 species of Acaulospora, 4 species of Gigaspora, 14 species of Glomus and 2 species of Scutellospora. The frequency of mycorrhizal fungus infection showed positive correlation with soil pH, moisture, water holding capacity, texture, total nitrogen, phosphorus, calcium, potassium, and magnesium. Especially phosphorus and nitrogen in the soil greatly influenced the plant root infection by AM fungi

    PHYTOCHEMICAL INVESTIGATION OF WEDELIACHINENSIS (OSBECK.) MERRILL
    (International Journal of Pharmaceutical and Chemical Sciences, 2014-01) H, Rehanabanu; N, Nagarajan
    Traditional medicine also known as indigenous or folk medicine comprises medical knowledge systems that developed over generations within various societies before the era of modern medicine. Traditional medicines are prepared from a single plant or combination of more than one plant. Indian contribution to herbal market and emphasis on novel research is continuously increasing. Hence in the present study an important medicinal herb Wedeliachinensis (Osbeck) Merrill was investigated for qualitative and quantitative phytochemical screening using standard methods. Preliminary phytochemical screening of various extracts of the leaves revealed the presence of various classes of compounds such as alkaloids, flavonoids, tannins and phenols. The results suggest that the phytochemical property of the plant for curing various ailments leads to the isolation of new and novel compounds

    PHYTOCHEMICAL SCREENING FOR ACTIVE COMPOUNDS IN GLORIOSASUPERBA LEAVES AND TUBERS
    (International Journal of Pharmacognosy and Phytochemical Research, 2012-03) H, Rehanabanu; N, Nagarajan
    Gloriosasuperba Linn. (Family: Liliaceae) is one of the endangered species among the medicinal plants which is a striking tuberous climbing plant with brilliant wavy-edged yellow and red flowers common in forest throughout India and in Andaman Islands. The objective of this study was to evaluate the phytoconstituents of Gloriosasuperba leaf and tuber extracts. All experiments were conducted following standard procedures. The results revealed the presence of various classes of compounds such as alkaloids, flavonoids, saponins, glycosides, steroids, phenols and tannins. Resins was not detected from any of the extract under study. The results of the various phytochemical tests indicated that the plant to be rich in various biologically active compounds which could serve as potential source of the crude drugs that can be used as a complementary source of traditional medicines. We recommend further research on this plant for possible isolation and characterization of the various chemical active substances.

    POTENTIAL INHIBITORY EFFECTS OF GLORIOSASUPERBA ON HUMAN PATHOGENIC FUNGI
    (Pharma Science Monitor, 2012-07) H, Rehanabanu; N, Nagarajan
    The different solvent extracts viz., acetone, dichloromethane, chloroform and methanol extracts of GloriosasuperbaL. (Liliaceae) were screened for antifungal activity, by disc diffusion method against human pathogenic yeast and mould. The test organisms included were Candida albicansand Aspergillusflavus. The methanol extract of tubers recorded high significant antifungal activity against all the tested fungi. The least activity was found in the chloroform extracts
