TL;DR: A new highly oxygenated ent-atisane diterpenoid, namely excagallonoid A (1), together with five known analogues (2, − − − 6) were isolated from the leaves and twigs of Excoecaria agallocha as mentioned in this paper.

TL;DR: In this article, the authors investigated the flora composition,physiognomy and structure, types and distribution of mangrove community, and the causes of ecological changes at Shenzhen Bay.
Abstract: Mangrove communities are made up of five species of mangrove plants including Kandelia candel,Avicennia marina,Aegiceras corniculatum,Acanthus ilicifolius and Excoecaria agallocha at Futian Mangrove Nature Reserve of Shenzhen. The authors investigated the flora composition,physiognomy and structure,types and distribution of mangrove community,and the causes of ecological changes at Shenzhen Bay. Accumulation and distribution of various metal elements in these mangrove communities were studied. The major element K,Na,Ca,Mg contents in forest soil were homologous from bottom to surface layer;element Fe,Mn were increased slightly from bottom to surface layer;element Cr,Ni,Pb,Hg,Cd and essential element Zn,Cu were increased obviously from bottom to surface layer. Accumulation and distribution of various metal element in five mangrove plants were studied and analyzed by the same way,element K,Na,Ca,Mg contents in all the organism of mangrove plants were sufficient,element Fe,Mn,Zn,Cu contents at all the organism in mangrove plants were in the order of FeMnZnCu. The element Cr,Ni,Pb,Hg,Cd contents had an obvious disparity at all the organism of plants,Ni content was maximum in K.candel and E.agallocha,Pb content was maximum in A.marina,Cr content was maximum in A.corniculatum,Cu content was maximum in A.ilicifolius,Cd and Hg contents were minimum in all the mangrove plants. Accumulation and distribution of various metal element in mangrove plants was dependent on contents of various metal element in forest soil.

16 Nov 2018TL;DR: In this paper, the authors investigated the type and structure of mangrove ecosystems in the Ujungpangkah coastal, region Gresik, East Java Province.
Abstract: Recent damage to the mangrove ecosystem has threatened the existence of this ecosystem. The mangrove ecosystem of the Ujungpangkah area in the Bengawan Solo estuary is one of the few (pristine remaining) mangrove ecosystems in East Java Province of Indonesia. This study aims to investigate the type and structure of mangrove ecosystems in the Ujungpangkah coastal, region Gresik, East Java Province. The ecosystem structure was investigated using mangrove vegetation analysis and spatial analysis using Normalized Difference Vegetation Index system analysis. Based on spatial analysis, the mangrove area in the Ujungpangkah was 1.445 hectares distributed among 4 (four) villages, consisting of high density (650 hectares), medium density (453 hectares), and low density (342 hectares). This area comprised 7 (seven) mangrove species i.e. Avicenia marina, Rhizopora mucronata, Rhizopora apiculata, Bruguiera cylindrica, Excoecaria agallocha, Sonneratia alba and Bruguiera gymnorrhiza. The Avicenia marina and Rhizopora mucronata were two mangrove species with the highest important value index at each growth level. The highest value index (71.73%) was attributed to Avicenia marina for the tree level, while Rhizopora mucronata was dominant at the sapling level (82.55%).

TL;DR: It is concluded that the ethanolic leaf extract of E. agallocha (EEEA)-induced apoptosis mediated cytotoxic and antiproliferative activity in the breast cancer MCF-7 cell lines can be developed into a new drug for treating breast cancer.
Abstract: Background: At present, Mangrove plants have gained importance in drug discovery due to the presence of many phytomolecules of medicinal importance. Excoecaria agallocha is widely distributed medicinal mangrove which has been traditionally used to treat sores, ulcers, and leprosy. Objective: The aim of the present study is to analyze the cytotoxic potential of Exoecaria agallocha leaves in terms of its antiproliferative activity, apoptosis induction, and cell cycle arrest in the breast cancer MCF-7 cell lines. Materials and Methods: The ant proliferative nature of the EEEA extract was determined by direct microscopic observation as well as 3-(4, 5-dimethyl-2-thiazolyl)-2, 5-diphenyl-tetrazolium bromide (MTT) assay by employing the different concentrations of the plant extract, and the IC50 values were calculated. Apoptosis-inducing potential was determined by double staining with acridine orange/ethidium bromide staining method and further confirmed by annexin V staining. Flow cytometry was performed with IC50 concentration of EEEA drug treated MCF-7 cells to determine arresting stage in the cell cycle progression. Results: There was a significant cytotoxic activity exhibited by the ethanolic extract of E. agallocha leaves (EEEA) in the direct microscopic as well as MTT assay with IC50 value of 56.5 μg/ml. Well prominent fluorescent microscopic images of morphological changes in the double staining method indicate the apoptotic potential of the extract which was further confirmed by annexin V staining. Suppression of cell cycle progression at subG1 and G1/G2 phases were also evidenced in the flow cytometry analysis. Conclusion: From the above results, it may be concluded that the ethanolic leaf extract of E. agallocha (EEEA)-induced apoptosis mediated cytotoxic and antiproliferative activity in the breast cancer MCF-7 cell lines which can be developed into a new drug for treating breast cancer.

TL;DR: Results from this study depicts that Sundarban is facing problems for increasing pollution load and water salinity and photosynthetic pigment concentration showed negative correlation with salinity i.e. increase in watersalinity causes decrease in pigment concentration.
Abstract: Present study describes a site specific variation of leaf elemental concentration and Photosynthetic pigment concentration in a mangrove plant Excoecaria agallocha in Sundarban, India. Three locations (S1, S2 and S3) were selected according to water salinity gradient in north to southward direction. Range of water salinity is from 19 ppt to 34 ppt. All elements (Fe, Cu, and Mn) are found to be higher in S1 followed by S2 and S3 except Zn. They follow the trend like Fe>Mn>Zn>Cu. Interestingly photosynthetic pigment concentration (total chlorophyll, chlorophyll-a, chlorophyll-b) showed negative correlation with salinity i.e. increase in water salinity causes decrease in pigment concentration. Results from our study depicts that Sundarban is facing problems for increasing pollution load and water salinity.
