“…Also, flavonoid has a positive effect of reducing RBC hemolysis, by protecting biological membranes of RBC from free radical which induces oxidative damage (Kitagawa et al, 1992;Asgary et al, 2005). Also, some investigators reported that the antioxidants present in the plant extract might trigger erythropoiesis and antioxidant activity (Shadu et al, 2006;Vargeshe et al, 2010;Lestari & Susanti, 2015). It seems in agreement with the present study as the TCL has flavonoids that capable as an antioxidant which may maintain the heme iron in its ferrous state and this could enhance erythropoiesis (Akah et al, 2008;Uboh et al., 2010;Shatoor, 2011).…”

This research aimed to determine the phytochemicals content of Terminalia catappa leaves extract (TCL) and its effects on the survival and blood profiles of ornamental fish (Betta sp) Ninety fish were randomly assigned into six triplicates groups and reared in various concentration of TCL: 0 (control), 125, 250, 375, 500, 625 ppm for 30 days. Temperature, Dissolve oxygen (DO), and pH were monitored during the trial. After 30 days, survival, Red Blood Cells (RBC), White Blood Cells (WBC), haemoglobin (Hb), lymphocyte, and total protein serum (TPS) were analyzed. Based on the phytochemicals test, saponin, triterpenoid, quinon, phenolic, tannin, and flavonoid were detected on the TCL. Temperature and DO were not affected by any concentration of TCL. The lowest pH (5.05) was found in fish medium immersed with 625 ppm of TCL. Adding TCL above 375 ppm resulted in significantly higher survival, RBC, and Hb. The highest WBC was found in fish immersed with 625 ppm whereas the lowest lymphocyte was found in fish immersed with 375 of TCL. However, immersing any various concentration of TCL did not affect on the TPS. In summary, immersing TCL above 375 ppm is beneficial to enhance survival, RBC, WBC, and Hb of Betta sp.

“…The IC 50 values of 1-3 and 5 and quercetin (positive control) recorded on a microplate reader with DPPH were 60, 28, 50, 500, and 30 lM, respectively. The IC 50 values of DPPH-radical-scavenging assay for compounds 32-39 and the positive control quercetin were 104, 85, 44, 75, 55, 50, 55, 40, and 30 lM, respectively [9][10][11][12].…”

“…Based on the traditional usage of this plant, we tested the extract for antioxidant activity using the DPPH-radicalscavenging effect on thin-layer chromatography (TLC). Although fatty acids, hydrocarbons, steroids, pectin, and sugars have been previously isolated from this plant [10], by taking the DPPH-radical-scavenging effect as the isolation guide, we isolated a flavone, luteolin (26), and its 7-O-b-glucoside (cynaroside) (27) (Fig. 5).…”

In our continuous search for bioactive natural products from natural resources, we explored medicinal plants of Bangladesh, targeting cancer-related tumor necrosis factor-related apoptosis-inducing ligand-signaling pathway, along with some other biological activities such as prostaglandin inhibitory activity, 1,1-diphenyl-2-picrylhydrazyl free-radical-scavenging activity, and cell growth inhibitory activity. Along with this, we describe a short field study on Sundarbans mangrove forests, Bangladesh, in the review.

As part of the search for new sources of mental health supplements, alcohol extracts of 11 Bangladeshi medicinal fruits and plants were investigated for neuropharmacological effects in mice and on ionotropic γ-aminobutyric acid receptors (GABA A receptors). The extracts of S. caseolaris, T. bellirica, S. cumini, and T. arjuna significantly potentiated the GABA-induced response of GABA A receptors expressed in Xenopus oocytes, though the extracts alone induced no response. In mice, administration of these extracts prolonged pentobarbital-induced sleeping time. Potentiation of GABA A receptor response reportedly generates anxiolytic, sedative, sleep-inducing and anesthetic activities in the human brain. Thus, these extracts may have potential regarding the development of a supplement with tranquilizing and sleepinducing effects that is beneficial for mental health.Keywords: Bangladeshi fruit, GABA A receptor, mangrove tree, pentobarbital-induced sleeping time, tranquilizer *To whom correspondence should be addressed. E-mail: aoshima@yamaguchi-u.ac.jp IntroductionAs society ages and the amount of lifestyle-related stress increases, there is increasing demand for the development of supplements which improve physical and mental health. Therefore, it is important to find new botanical resources for use as active ingredients for supplements or drugs.Over 1000 of the estimated 5000 species of phanerogams found in Bangladesh, Southeast Asia are regarded as having useful chemical constituents (Goni, 2003). A variety of these plants have been used traditionally as astringents, antiseptics, tonics, febrifuges and fish poison as they possess active compounds such as alkaloids, polyphenols, saponins, tanic acids, resins, waxes and fragrant compounds (Goni, 2003). However, despite the consumption and use of these herbs and fruits, little scientific data clarifying their physiological activities are available. There is some information available relating to their chemical constituents (Goni, 2003;Sadhu, et al., 2006) and biological properties (Scartezzini et al., 2005;Abdille et al., 2004; Lee et al., 2005). Our laboratory has recently reported the antioxidative, antiamylase, antiglucosidase and antihistamine release activities of some Bangladeshi fruits (Hossain et al., 2008).Various neurotransmitter receptors are involved in defining mental state, particularly the ionotropic γ-aminobutyric acid receptors (GABA A receptors), which are the main inhibitory neurotransmitter receptors in the human brain (Hossain et al., 2007). These heteropentamers composed of various α, β, γ, δ and ε subunits were found to be expressed in Xenopus laevis oocytes (Trauner et al., 2008). The potentiation of the response of these receptors by drugs such as benzodiazepine, pentobarbital and anesthetics induces tranquilizing, sleepinducing or anesthetic responses in humans (Nicholls, 1994;Chebib & Johnston, 2000;Harrison et al., 2000). It was found that fragrant compounds such as terpinen-4-ol, 1-octen-3-ol, and linalool potentiated the response of GAB...
