BIOACTIVE SUBSTANCES OF MANGROVE Excoecaria agallocha AS SHRIMP DISEASES INHIBITOR

Abstract: Excoecaria agallocha mangrove species is suspected of having bioactive material which can be used as bacteriostatic agent, water nutrient stability and shrimp diseases reduction Hexane, acid ethyl acetate, neutral ethyl acetate, and water were used as solvents Chemical compounds of mangrove bioactive were classified by color reaction on TLC and identified by spectroscopic method The highest inhibition zone crude extract of bioactive mangrove toward several Vibrio sp from the shrimp ponds show that V mimicus are 1035 ± 005 mm at 10 µ L and 126 ± 005 at 20 µ L The highes inhibition zone produce by fraction Et-OAC neutral with V costicola are 183 ± 005 at 10 µ L and 239 ± 005 at 20 µ L Keywords : Bioactive, mangrove , bactericide

Growth and Organic Constituent Variations with Salinity in Excoecaria agallocha L., an Important Halophyte

Abstract: The present investigation was made to study the effect of different concentrations of sodium chloride and potassium chloride on growth and organic constituents of the seedlings of Excoecaria agallocha. The plant could survive a wide range of 100-500mM of salt concentrations. The upper limits for the survival of the seedlings were upto 500mM NaCl and 400mM KCl. The highest numbers of leaves, leaf area, fresh and dry weight were recorded at 300mM NaCl and 200mM KCl treatment. Beyond these levels, the growth parameters reduced drastically. Organic compounds such as amino acid and sugar decreased upto optimum level of 300mM NaCl and 200mM KCl and increased at higher concentrations. The starch and chlorophyll content increased upto 300mM NaCl and 200mM KCl, beyond these levels the contents decreased marginally. The proline content increased with the increasing salinity of both the salts.

Changes to the polyisoprenoid composition in aging leaves of mangrove plants

Abstract: Polyisoprenoid (polyprenols or dehydrodolichols and dolichols) content and composition of four true mangrove plants namely Excoecaria agallocha, Lumnitzera racemosa, Rhizophora apiculata, and R. lamarkii were investigated with particular emphasis on leaf senescence. The distribution and occurrence of polyisoprenoids was analyzed using the two-plate thin layer chromatography (2P-TLC) method. The age of the leaves was divided into young leaf, leaf, and yellow leaf. In the leaves, the distribution of polyisoprenoid was found to show the presence of both polyprenols and dolichols. The occurrence of ficaprenols (C50–C55) was observed in young leaves and leaves of the mangrove samples studied. On the other hand, dolichol contents were not altered in the leaves with senescence. By contrast, longer polyprenols were found in yellow leaves of E. agallocha, L. racemosa, and R. apiculata. In addition, it should be noted that there were changes to the polyprenols in leaf senescence identified. Furthermore, the formation of ficaprenols, longer polyprenols, and dolichols was modulated in the mangrove plants. These findings suggest that the accumulated polyprenols in the yellow leaves may be due to the catalyzation process that converts ficaprenols into longer polyprenols.
