Authors:Asim Kumar Paul, Md. Jahangir Alam, A.H.M.Jahangir Alam Pages: 1 - 22 Abstract: Preliminary survey work was done in Rangamati and Khagracharihill district in the Chakma community. The study was carried out on medicinal plants used by the Chakma community. Chakma people are mostly residing in the deep forest and depend on their own traditional health care system. Information was collected by interviewing traditional herbal healers (locally called Baddhya) and various elderly men and women. All the plants were listed along with their scientific name, family, chakma name, habit, used parts and mode of preparation. A total of 125 plant species under 46 families have been identified which are used to treat different diseases by the traditional herbal healers. Fabaceae, Rubiaceae and Euphorbiaceae are the most frequently used family to the number of species used by the Chakma Community. Mostly leaves are used for the preparation of folk medicine.

Authors:AKHARAIYI Fred Coolborn, DINA Abayomi Olabanjo, OKAFOR Arthur Chinedu Pages: 23 - 41 Abstract: The development of resistance in many microorganisms to synthetic drugs, inability of these synthetic drugs to provide cure for some diseases and infections calls for serious attention. Due to this development, the antimicrobial activity, preliminary phytochemical analysis and antioxidant properties of aqueous and methanol leaf extracts ofPhyllanthusmuellerianus was studied. Well in agar diffusion method was used for the antimicrobial test. Chemical methods wasused to preliminarily screen for phytochemical constituents and in vitro antioxidant quality. The aqueous leaf extract possessed higher antibacterial potency (14.0±0.16–37.3±0.03 mm) on the test bacteria species than the commercial antibiotics (6.2±0.5–20.8±0.3 mm) and antifungal (6.5±0.07-17.7±0.4 mm). Methanol extract only inhibited Candida krusei with zone of 4.5±0.3 mm. In both the qualitative and quantitative phytochemicals screened, aqueous extract was of higher yield than methanol extract. The antioxidant of the leaf extract in free radical scavenging(DPPH) and hydroxyl radical scavenging activity were higher in aqueous extract than methanol extract while ferric reducing antioxidant was only more in methanol extract. As valuableantimicrobial potential, phytochemical constituents and antioxidant properties were exhibited by P. muellerianus leaf extract, it may enhance a large segment of the world population to rely upon the use of the plant as alternative medicine for healing of the many microbial disease origins that plaque aroundthe world.
Authors:MACHHOUR Hasna, IDLIMAM Ali, MAHROUZ Mostapha Mostapha, KOUHILA Mohamed, SAMRI Salah Eddine Pages: 42 - 55 Abstract: Peppermint leaves (Mentha x piperita L.) washed with water or citric acid solution () were dried under open sun. The drying kinetics on a thin layer of peppermint tea was studied at temperature of 80 °C and at drying air velocities of. An indirect forced convective solar dryer in continuous was used in the experiments. The drying time is almost identical for the pilot and treated peppermint tea. It is 80 min. Ten mathematical models have been used for describing the drying curves. The Wang and Singh models showed the best fitting of experimental data of treated peppermint tea with citric acid solution and diffusion approach model is the best to describe the drying curves of peppermint tea washed with distilled water.

Authors:SAID HASSANE, SATRANI B., GHANMI M., Aafi A, M. LACHKAR, Chaouch A. Pages: 56 - 66 Abstract: Nowadays, many researches are interested in finding natural and antiradical substances because, in addition to their nutritional values, they could also help to balance the anti-protection systems of antioxidant and to protect against oxidative stress-related diseases, particular cardiovascular and neurodegenerative diseases, diabetes and cancer. Thus, the use of medicinal and aromatic plants for their therapeutic effects, prompted us to perform investigations on the antiradical activity of the essential oil of Ocimum basilicum, species used, in particularly, folk medicine in Comoros. The antioxidant activity was demonstrated by the spectrophotometric method of DPPH (2,2-diphenyl-1-picrylhydrazyl). The result showed that the essential oil of Ocimum basilicum has an anti-radical effect compared to BHT (Butylhydroxytoluene) as antioxidant reference. Concentration value of IC50 is 7.75 mg/mL. The major component of the essential oil of Ocimum basilicum was methyl chavicol (estragole) with a rate of 80.04%. PubDate: 2019-06-02 Issue No:Vol. 5, No. 2 (2019)
Authors:Myriam Ben salah, Tarek Barhoumi, Manef Abderraba Pages: 67 - 97 Abstract: Objective :The aim of this study was to document the diversity and use of natural plants in the island of Djerba (Tunisia) in traditional pharmacopoeia and other uses in order to develop an ethnobotanical catalogue that could subsequently be the subject of scientific research.Materials and Methods: The technique of semi-structured interviews was used with people originating and residing or not in Djerba. Occasional conversations and direct observations were exploited for one year.Results: We have identified 86 plants out of 122 mentioned belonging to 80 genera and 43 families. Asteraceae were the most important family represented by 13 species followed by Lamiaceae and Poaceae (7 species each). The results showed that 45 species have medicinal uses (52.32%). Leaves were the most used parts (59% of species for medicinal use). Decoction was the most common method for preparing remedies.Conclusion: This study provides an important source of information for flora valorization in the studied region. The results could form a database for the search of new natural substances with added value. PubDate: 2019-06-02 Issue No:Vol. 5, No. 2 (2019)
