The present study was conducted to evaluate the effect of physicochemical and phytonutients qualities of aloevera gel fortified yoghurt. Three different concentration of yoghurt were developed with 10, 15 and 20 percent of aloevera gel addition. Based on sensory evaluation,the sample AY2 has scored higher in the overall acceptance among the samples. On the other hand, the pH and titratable acidity were found to be inversely proportional to the concentration of alovera gel addition in yoghurt. In theresults offat content that all the experimental samples were shown gradual decreasing effect when compared with the control sample. As per the result of protein, Vitamin C and minerals of experimental samples have foundconstant effect when compared to control sample.The content of fiber was absent in control whereas in the aloevera gel concentrated samples AY1, AY2 and AY3 contains 0.19, 0.23 and 0.26 respectively. On the qualities of phytonutrients of steroids, saponins, phlabotannin and anthroquinone were founde in all the samples except control.

Cnidarians comprise an old and diverse animal phylum, and possess a wide variety of biologically active substances. Sea anemones contain a diversity of interesting biologically active compounds including some potent toxins. In the present work, the sea anemones Stichodactyla mertensii and Stichodactyla gigantea, collected from the Mandapam coast, are characterized biomedically and pharmacologically. The crude protein was obtained by using methanol and aqueous extracts. The respective protein contents of S. mertensii and S. gigantea were found to be 2.10 µg/mL and 1.87 µg/mL. The methanol and aqueous extracts of S. mertensii and S. gigantea yielded six and nine bands by SDS-PAGE on 12% gel. In the hemolytic assay, both extracts exhibited hemolytic effect on chicken, goat, cow and human erythrocytes ('A' , 'B' and 'O'). The neurotoxic effects of these crude extracts were determined in vivo using the sea shore crab Ocypode macrocera and mortality was observed. The mouse bioassay for lethality was performed on male albino mice. The crude extract of S. mertensii showed higher lethality (58 seconds at 1 mL-dose) than that of S. gigantea (2 minutes and 10 seconds at 0.75 mL-dose). The analgesic activity test was also carried out on albino mice by Eddy's hot plate and tail-flick methods. The extracts showed moderate analgesic effect by both hot-plate and tail-flick methods. These characteristics emphasize the need for the isolation and molecular characterization of new active toxins in S. mertensii and S. gigantea.
