Different parts of this tree have been used in folklore medicine and research studies also exhibited various medicinal properties such as antibacterial, anti-fungal, anti-inflammatory, antioxidant, anti-tumour, anti-HIV, hepato-protective and anti-diabetic of this plant. This review work focused on phytopharmacological significance of T. catappa L. besides its traditional medicinal uses and major chemical constituents reported on this tree. Pharmacological activities reported in the review provide scientific evidences for the numerous traditional uses and folklore claims of this plant. Key words: Terminalia catappa L., Ethnomedicinal uses, Pharmacological activity. INTRODUCTION branches are formed in a characteristic, bifurcating pattern. The tiered crown becomes flatter with widespread branches in older Combretaceae is one of the largest families of flowering plants specimens. The trunk is usually straight and reasonably including trees, shrubs, and lianas comprising about 20 genera cylindrical, but in exposed coastal situations it may be crooked and 600 species. Terminalia is a genus of large trees belonging and/or leaning. Buttresses, when present, are up to 3 m (10 ft) in to the family Combretaceae, comprising around 200 species height, variable, straight to curved, thick to thin, sometimes distributed in tropical regions of the world. This genus gets its branching. Large trees may develop big, occasionally branching name from Latin word Terminus, referring to the fact that the buttresses and often have twisted, leaning trunks (Figure 1). leaves appear at the very tips of the shoots.

The genus comprises approximately 250 species distributed throughout the tropical regions mainly in Africa and Asia. With increasing chemical and pharma- cological investigations, Combretum has shown its potential as a source of various secondary metabolites. Combretum ex- tracts or isolates have shown in vitro bioactivitities such as antibacterial, antifungal, antihyperglycemic, cytotoxicity against various human tumor cell lines, anti-inflammatory, anti-snake, antimalarial and antioxidant effects. In vivo studies through various animal models have also shown promising results. However, chemical constituents and bioactivities of most species of this highly diversified genus have not been investigated. The molecular mechanism of bioactivities of Combretum isolates remains elusive. This review focuses on the chemistry of 261 compounds isolated and identified from 31 species of Combretum. The phytochemicals of interest are non-essential oil compounds belonging to the various struc- tural groups such as terpenoids, flavonoids, phenanthrenes and stilbenoids. Keywords: Combretum, phytochemistry, pharmacology, terpenoids, polyphenolic compounds, antibacterial activity, antifungal activity.

  • Plant Life of Western Australia
    INTRODUCTION The characteristic features of the vegetation of Australia I. General Physiography At present the animals and plants of Australia are isolated from the rest of the world, except by way of the Torres Straits to New Guinea and southeast Asia. Even here adverse climatic conditions restrict or make it impossible for migration. Over a long period this isolation has meant that even what was common to the floras of the southern Asiatic Archipelago and Australia has become restricted to small areas. This resulted in an ever increasing divergence. As a consequence, Australia is a true island continent, with its own peculiar flora and fauna. As in southern Africa, Australia is largely an extensive plateau, although at a lower elevation. As in Africa too, the plateau increases gradually in height towards the east, culminating in a high ridge from which the land then drops steeply to a narrow coastal plain crossed by short rivers. On the west coast the plateau is only 00-00 m in height but there is usually an abrupt descent to the narrow coastal region. The plateau drops towards the center, and the major rivers flow into this depression. Fed from the high eastern margin of the plateau, these rivers run through low rainfall areas to the sea. While the tropical northern region is characterized by a wet summer and dry win- ter, the actual amount of rain is determined by additional factors. On the mountainous east coast the rainfall is high, while it diminishes with surprising rapidity towards the interior. Thus in New South Wales, the yearly rainfall at the edge of the plateau and the adjacent coast often reaches over 100 cm.

This study aimed to evaluate the performance of turbidity removal in water by using Terminalia catappa (Talisay) as natural coagulant. The coagulation active agent in the leaves of Terminalia catappa was extracted with 1.0 molar (M) Sodium Chloride (NaCl) solution. Water from Cagayan River, Tuguegarao City, with increased turbidity of 200 Nephelometric Turbidity Units (NTU) was used in this study. This study was done using Completely Randomized Design with loading doses of 2, 3, 4, and 5 mL/L of the stock solution with 5 g of Terminalia catappa leaf powder in 100 mL 1.0 M NaCl solution as coagulant. The turbidity, pH, and coliform count were determined for all the samples. The turbidity for the samples ranged from log101.81 to log101.33 NTU. The 5 ml/L treatment of Terminalia catappa showed the lowest residual turbidity where 88% turbidity was removed from the sample. The pH values ranged from 7.27 to 7.46.

  • Evaluation of the Chemical Composition, Nutritive Value and Antinutrients of Terminalia Catappa L
    International Journal of Engineering and Technical Research (IJETR) ISSN: 2321-0869 (O) 2454-4698 (P), Volume-3, Issue-9, September 2015 Evaluation of the Chemical Composition, Nutritive Value and Antinutrients of Terminalia catappa L. Fruit (Tropical Almond) Justina I. R. Udotong, Michael I. Bassey Terminalia catappa L. is a large, deciduous tree (Plate Abstract— Terminalia catappa L. fruits were analyzed to 1.0) with smooth grey bark and whorled branches that form a establish their chemical composition and nutritive properties in canopy and is found in tropical and subtropical regions. The order to investigate the possibility of promoting their usage as fruit is large (1.2-2.3”), edible, fleshy, green (unripe) and human food or animal feed. The seeds (enclosed in the hard yellow or red (when ripe) containing a single seed. The fruit stone-like core) and the pulp (succulent exocarp and fleshy has a husk (34.08%), a porous and fibrous pericarp (8.97%), fibrous mesocarp) were analyzed. Proximate analyses showed that the seeds and pulp contained 47.34±0.03% and an exocarp which is relatively thin and smooth while the hard 80.93±0.05% moisture, 28.70±0.59% and 8.75±0.01% crude endocarp (46.63%) encloses an edible kernel (10.32%) [5]. protein, 5.19±0.08% and 4.79±0.17% ash, 3.76±0.34% and 3.10±0.03% crude fibre, 44.64±0.11% and 0.51±0.02% fat, 17.71±1.12% and 82.85±0.23% carbohydrate and 587.40±7.28kcal and 370.99±1.14kcal of energy, respectively.
