The successive Soxhlet extract ofDigera muricata(L.) Mart. (Amaranthaceae) were extracted using petroleum ether, chloroform, ethanol and distilled water in ascending order of the polarity. These extracts were subjected to screening of preliminary phytochemicals tests. The results indicate the presence of alkaloids, flavonoids, phenols, tannins, terpenes and saponins. These extracts further subjected to the antimicrobial activity. Among the bacteria used, the petroleum ether extract gave highest zone of inhibition at 400 µg/well againstV. cholerae.Similarly, in fungi the ethanol extract exhibited highest zone of inhibition at 400 µg/well againstCandida albicans.

Objective: Population explosion is a foremost problem and its control in colonized countries may have an effect on the economic growth, in this regard family planning has been promoted through several methods of contraception, however current methods of contraception result in undesirable side effect. Thus there is a need to replace these agents with potent drugs with least or zero side effects. Hence, the present study was undertaken to evaluate the antifertility properties of and on female albino mice. Actiniopteris radiata Selaginella bryopteris Material and methods: Experimental mice were orally administered with methanol extract of (175 and 300 mg/kg body Actiniopteris radiata weight) and (250 and 500 mg/kg body weight) for 30 days. Effect of the treatment on female Selaginella bryopteris reproductive organ was investigated and level of oestrogen was determined by ECLIA oestrogen standard kit. Quantitative estimations of protein, cholesterol and alkaline phosphatase of blood serum were carried out using Biosystems Diagnostics standard kit. : The treatment showed decrease in weight of the ovary Results and conclusion and decrease in oestrogen level and on the other hand histological changes were also observed. The overall results of the present study revealed that the low dose of (175 mg/kg body weight) methanolic extract of induced infertility A. radiata whereas in high dose (300 mg/kg body weight) it is not observed. While had notshown much significant S. bryopteris variation in female albino mice when compared to control.

In the present work, the effect of NaCl on catalase and peroxidase activity of Chlorella vulgaris Beijerink was investigated The C. vulgaris was treated with different concentrations of NaCl viz., 0.1, 0.2, 0.3 and 0.4M besides control over 10, 20 and 30 days. The results exhibited increase in the catalase and peroxidase activity up to 0.3 M, whereas it was decreased at 0.4M for all the cultures over all the durations. The study revealed that, increased activity of catalase and peroxidase was an adaptive mechanism to reduce the H2O2 and offer protection against oxidative damage and tolerance against salt.

A survey of Flora of Gulbarga and Bidar Fort, Karnataka was carried out during the year May-2007 to April-2008. During this survey identified 221 species of plants belonging to 63 families, which consist of Algae 20 species, Lichens 2 species, Bryophytes 08 species, Pteridophytes 08 species, Gymnosperms 06 species, Angiosperms including Monocotyledons 27 species, 23 Genara, 04 family, and Dicotyledons 150 species, 121 Genera, 46 Families, were recorded. Three species i.e Hyptis suaveolens, Lantana camara, and parthenium hysterophorus, were found as invasive weed species.
