(see constituents above) (36)
Antidiabetic Potential / Leaves: Studies have shown that T. catappa possess anti-diabetic properties. Studies on alloxan-induced diabetic allbino rats subjected to aqueous and cold extracts of fresh tender leaves showed a significant decrease in glucose level and regeneration of necrotic beta cells of the pancreas. Further studies are suggested to discover the regenerating factor. (37)
• Antifungal Against Candida spp. / Leaves: Study showed T. catappa leaf extract, fractions, and subfractions have antifungal activity against Candida spp. Crude hydroalcoholic extracts (TcHE) and fractions inhibited the growth of all tested Candida strains with the n-butanol fraction showed the best activity. (see constituents above) (38)
• Anti-Helicobacter pylori / Antiulcer: Study evaluated the gastroprotective and healing effect of aqueous fraction of T. catappa leaves in experimental rodent model. Oral treatment with the FrAq significantly decreased the number of ulcerative lesions induced by ethanol and ischemia/reperfusion injury. The activity was mediated by the activation of defensive mucosa-protective factors i.e., increased mucus production, NO pathway and endogenous prostaglandins. The extract also exhibited significant activity against Helicobacter pylori. Fraction analysis yielded different phenolic compounds, including punicalagin, punicalin, and gallagic acid, among others. (39)
• Surface Water Treatment / Turbidity Removal / Leaves: The use of inorganic coagulants for preliminary water treatment present environmental hazards. Study evaluated the used of T. catappa as natural coagulant. Results showed a potential for Tc leaf extract as natural coagulant to remove turbidity in water. However, the leaf extract has no effect on basicity and acidity, and has no observable antibacterial effect on water. (40)
• Mutagenicity / Leaves: Study evaluated a hydroalcoholic extract of leaves by HPLC-PDA to quantify compounds and evaluate its mutagenic activity by Salmonella/microsome assay on several S. typhimurium strains (TA98, TA97a, TA100, and TA102). Mutagenicity was observed in TA100 and TA97a strains. The complex mixture of punicalagin (the most abundant polyphenol found in the leaves), its derivatives and other compounds found in the extract may explain its mutagenicity. While the mutagenicity was observed only in high concentrations, study advise caution for medicinal use. (42)
• Thermogravimetric / Food Supplement Potential / Fruit: Study evaluated the chemical composition, morphology, and thermogravimetric behavior of Tc pulp. Analysis showed considerable energy value based on lipid content, with a fiber content that enhances the functional properties of the fruit. Thermogravimetric qualities suggest the raw fruit material has great potential for industrial use as dietary complement or supplement ingredient in food products due to high absorption rate of water soluble and/or lipid-based compounds. (43)
• Antifungal / Synergistic Combinations: Study evaluated extracts and fractions of Terminalia catappa, Terminalia mantaly and Monodora tenuifolia, alone and in combinations for antiifungal activity against isolates of C. albicans, C. glabrata, C. parapsilosis and Cr. neoformans. Synergistic interactions were observed with combinations of subfractions of Mt, Tm, and Tc. (44)
• Safety Study in Pregnant Rats: Study evaluated the influence of aqueous stem bark extract of T. catappa on pregnant Wistar rats and brain glucose-6-phosphate dehydrogenase (G6PD) activity. Results of dose extract of 400 mg/kbw consumed during pregnancy showed relatively safety, and did not cause abnormalities in foetus or influence changes in G6PD. (45)
• Wound Healing / Bark: Study evaluated the wound healing activity of T. catappa on excision wound models in rats using an ointment formulation of a bark extract on excision wound model. Results showed significant wound healing. Animals treated with the ointment showed 97% reduction in wound area compared to control animals (81%). Treatment induced faster epithelization. (46)
• Antimicrobial / Antioxidant / Bark: Study evaluated a methanol bark extract for antimicrobial and invitro antioxidant activity. Results showed potent antimicrobial activity. Among all fungal strains, Aspergillus niger showed highest zone of inhibition, and among bacterial strains, Bacillus subtilis showed highest sensitivity. On DPPH assay, a methanol bark extract showed similar activity as that of standard ascorbic acid. (47)
• Seeds as Food Source: Study evaluated the potential use of seeds as a new dietary source, analyzed its nutritional and antinutritional properties and determined the effect of roasting. Results showed Tc seeds contain considerable amount of minerals comparable to other widely consumed nuts. Contents of phenolic compounds and phytates (IP4+IP5+IP6) in raw seeds were 64.9 g of GAE/g and 2,110 mg/100g, comparable to values in edible nuts. Roasting of the seed causes reduction of amino acid, IP6, trypsin inhibitor activity and phenolic compound value. (see constituents above) (48)
• Antihyperglycemic / Fruit: Study evaluated the anti-hyperglycemic effect of a fruit extract of T. catappa in a diabetic rat model. The hydroalcoholic fruit extract significantly decreased blood glucose, urine volume, and increase body weight in a dose-dependent manner. The effect of T. catappa at 30 mg/kg and 40 mg/kg dose was significantly more than glibenclamide. Extract treatment and glibenclamide brought back the level of HbA1c to normal levels. The addition of glibenclamide to Tc did not produce additional effects on blood glucose and HbA1c. (50)
• Effect on Fish Bacteria, Fungi, and Ectoparasites / Alternative to Chemicals and Antibiotics / Leaves: Study suggests the water extract of leaves of Indian almond has positive effects for the treatment of fungi, bacteria, and fish ectoparasite and can be used as alternative treatment to replace chemicals and antibiotics in treating fish pathogens. (52)
• Antisickling / Leaves: Study evaluated the effect of Tc extract of dried fallen leaves for antisickling activity. Bioactivity guided fractionation of methanolic extract showed the highest antisickling activity in the erythrocyte sickling model came from the triterpenoid components (F3, K=0.0037 min-1). The most active components were shown to be two triterpenic acids. Results show a scientific basis for the application of the extract in the management of sickle cell anemia in traditional medicine. (54)
• Antimycobacterial / Anticandidal / Antioxidant / Leaves: Study evaluated the antimycobacterial, anticandidal and antioxidant activities of T. catappa. Results showed good antimicrobial activity against both gram negative and gram positive bacteria, good antimycobacterial activity against M. smegmatis and M. tuberculosis, promising activity against Candida species, and good antioxidant activity using various assays i.e., DPPH radical scavenging, FRAP, with high phenolic and flavonoid content. (55)
• Biosorbent / Pb, Cd, and Cu Ions / Fruit Shell: Study reported on the use of fruit shell, an agricultural waste, as a low cost biosorbent for the removal of Pb (II), Cd (II), and Cu (II) ions in liquid waste. (56)
• Insecticidal: Study evaluated the aqueous extracts of four medicinal plants for their effects on Drosophila melanogaster larval mortality and pupation. Terminalia catappa was the only plant that raised mortality rates of D. melanogaster larvae and mimicked properties of commercial insecticide in pupation rates. (57)
• Hypoglycemic Effect / Leaves: An aqueous decoction of leaves of Terminalia catappa exhibited a dose-dependent hypoglycemic effect in rabbits. The dose of 40 mg/ml was the most effective among administered doses, reducing hyperglycemia to normal value of about 1.11 g/l after 90 minutes. The antidiabetic effect was attributed to alkaloids, sterols, and triterpenes. (58)
• Wound Healing / Leaves: Study evaluated the wound healing activity of ointment formulations from ethanolic extract of both green (GL) and brown (BL) Indian almond leave in mice (Mus musculus) with wounds inflicted under chloroform anesthesia. All groups of mice treated with ethanol extract of either GL or BL higher than 20% showed significant wound healing compared to mice treated with simple ointment, Pi (povidone iodine), or control. (59)
• Enzyme Inhibitory Activities / Antihypertensive / Leaf and Stem Bark: Study evaluated the acetylcholinestrase, arginase, phosphodiesterase-5 and angiotensin-1-converting enzyme inhibition and antioxidant properties of phenolic rich extracts from almond leaf and stem bark. The phenolic rich extracts showed remarkable enzyme inhibition activity in a concentration dependent manner, with high antioxidant activities. The stem bark extract showed higher inhibitory effect against ACE activity than leaf extract. Results suggest the leaf and stem bark can be potential natural source for development of novel antihypertensive agent. (60)
