Salt crystals on avicennia marina (black mangrove) var resinifera leaves. Int J Pharm Biol Arch. Avicennia marina (Forssk.) There are many salt-secreting glandular hairs on the lower epidermis, and many layers of palisade tissues which account for about 2/3 in the mesophyll tissues. The SI values of the extract for the before and after virus attachment stages of viral replication cycle were 87.1 and 41.9 for HSV-1. The IC50 values of the extract were 66 µg/ml and 137.24 µg/ml for before and after virus attachment stages of HSV-1 replication cycle respectively. Phytochemical analysis was carried out as per Wagner and Bladt (1996). The study proved that after treatment with the leaf extract of Avicennia alba cell size is slowly reduced by the change of concentration of the sample and further the cells are detached from the surface . In Avicennia marina, miR156 had higher expression levels in leaves and roots and lower levels in stems, flowers and seeds. Augustic acid, a new oleanane derivative, and a stigmasterol glycoside were isolated from the roots of Ambroma augusta. Excretion was greater in 100% than 50% seawater but the reverse was true for transpiration. Diabetes mellitus (DM) is a metabolic disease that can affect the central nervous system and behavioral traits in animals.

In this section, the effect of salinity on the biomass of selected mangrove species (Sonneratiaapetala, Avicennia marinaand Excoecariaagallocha) has been analyzed considering the data of 10 stations of Indian Sundarbans with variable salinity. Vierh. The Kiswahili name Uchu (coastal Kenyan) and Mtswi (Giriyama) are … Leaves Leaf-blades elliptic or ovate-elliptic to elliptic-lanceolate, 3–12 cm. Root and xylem sap salinities were linearly related to substrate salinity but leaf Na+ increased to a maximum, indicating that control of leaf salt content is at the foliar, rather than the root level. Leaves leathery with lamina narrow-obovate to obovate or elliptic, 3.5–12 cm long, 1–4 cm wide, apex acute … 2007). In another study, the methanolic pneumatophore extracts were also reported for their AGE inhibition potential that indicates the potential of this plant to control the post diabetic complications (Mahera et al. MOHAMMAD2 The plant is the most widespread mangrove in the tropical and subtropical regions of Indo-West-Pacific area. Zeorin (1), a hopane-type pentacyclic triterpenoid lacking on oxygen function at C-3, was isolated from the roots of Tripterygium regelii. is a historic plant, well-known for many centuries in traditional and folk use medicine. © 2008-2020 ResearchGate GmbH. complementary (filling) tissue, which consists of thin walled spheroidal cells by intercellular spaces. 299. Antimicrobial potential of leaf extracts of ten mangrove species from Indian Sundarban. Diabetes mellitus is a heterogeneous group of metabolic disorders characterized by persistent hyperglycaemia and becoming a serious threat to mankind health in all parts of the world. In addition, the location of functional groups can often be narrowed down by consideration of the fragmentation pattern. In other plants that do end up containing excess salt, some accumulate it into older leaves so it can be shed with the leaves. Are often more highly valued for timber, firewood, charcoal, dye and tannin production. The CC50 of the extract was 5750.96 for Vero cells. 2017). Avicennia marina (Forssk.) The purpose of present research is to study the inhibitory effect of aqueous extract of Avicennia marina on candida albicans in laboratory conditions. A new triterpenoid acetate derivative, compound 7, Calotropisis, was isolated and characterized by spectral methods. These naturally occurring compounds are found to be concentrated in the plant's leaf, stem/bark and aerial roots. (2011); Gomes e Sousa (1967) gives nhamesso (Xironga) and mussu (Quimuane) for Mozambique. (Version 4.1) and the virtual screening to know receptor-ligand binding affinity and energy value by using the software, PyRx (Version 0.8). var. The TNF-α (receptor) was obtained (PDB ID: 2az5) from the European Protein Data Bank (PDBe) and the information on selected fifteen ligands (phytochemicals) and one synthetic ligand (Ibuprofen) were taken from PubChem database. Compounds 1 and 2 are reported for the marina. When combined with tree density, girth distribution and previous estimates of nodes production (Table 1), these relationships allowed to estimate that Avicennia marina in Khor Alkharar produced 7871.5 leaves m −2 year −1 and the stand in Thuwal Island produced 7345.2 leaves m −2 year −1, which, provided the life span of Avicennia marina leaves is ≤1 year, is equivalent to the leaf litter fall fluxes, as grazing losses … Avicennia, also called black mangrove, genus comprising at least eight species of trees or shrubs in the family Acanthaceae. Avicennia marina leaves (0.3 g) were homogenized with 1 ml of 50 mM phosphate buffer solution (pH 7.8), and then centrifuged at 10,000 g at 4 °C for 15 min. Family Acanthaceae. 2007), α-amyrin (2), ursolic acid (9). The diurnal excretion pattern, with exudation minimal during the day and maximal during the night, showed a negative correlation with the daily. … Recently, the outbreak of herbivorous insect, Phyllocnistis citrella Stainton, a leaf miner, have impacted on the growth of A. marina. The plants belonging to the genus have both ecological and economic benefits. Their fleshy, leathery leaves are opposite and entire and feature salt-exuding glands on the upper and lower surfaces. Lenticels on the pneumatophores of Avicennia marina were studied by Scanning Electron Microscopy (SEM) in order to relate their development and structure of their function as aerating deliver oxygen in mangrove’s root. In this study, we performed triterpenoid profiling and RNA sequencing of A. marina leaves. The leaves are thick, 5 to 8 cm (2.0 to 3.1 in) long, a bright, glossy green on the upper surface, and silvery-white, or grey, with very small matted hairs on the surface below. Transcriptome mining for genes encoding P450 involved in the CYP716 family, and subsequent enzymatic activity assays with three triterpene scaffolds that have been identified in A. marina (Basyuni et al.
