I (Jan. - Feb. 2016), PP 73-78 www.iosrjournals.org Physico-chemical and Nutritional Characteristics, and Antimicrobial Activity of Oil Palm Syrup, Raffia Palm Syrup and Honey *Fred Omon Oboh, Lorenta Iyare, Monday Idemudia and Stephen Enabulele. Department of Basic Sciences, Benson Idahosa University, P.M.B. 1100, Benin City, Nigeria. Correspondence e-mail: [email protected], [email protected] Abstract: The physico-chemical characteristics and antimicrobial activity of oil palm syrup, raffia palm syrup and honey were studied. The materials contained mainly carbohydrate (64.76-68.79%) and water (28.05- 31.50). They exhibited similar densities (1.23-1.26 g cm-3) and pH (3.51-4.18), and had low ash (0.30-0.50%), protein (0.24-1.04%) and lipid (2.20-3.62%) content. They had modest content of Fe (2.35-3.30 mg/100g), Ca (37.06-79.05 mg/100g), and phenolic compounds (125.93-185.44 mg GAE /100 g), and were rich in potassium (325.12-628.56 mg/100g). They contained non-enzymatic browning products (browning intensity was 0.71 for honey, 0.159 for raffia palm syrup and 0.175 for oil palm syrup). The materials exhibited antimicrobial activity against clinical strains of Pseudomonas aeruginosa, Bacillus cereus, Escherichia coli and Staphylococcus aureus. The antimicrobial activities of dilute solutions (0.1 ml, 0.5% aqueous solutions) of the honey (containing 360 µg dry matter) and syrups (raffia, 360 µg and oil palm, 340 µg dry matter) were similar to that of 10 µg of the antibiotic streptomycin.

    Outline of Angiosperm Phylogeny

    Outline of angiosperm phylogeny: orders, families, and representative genera with emphasis on Oregon native plants Priscilla Spears December 2013 The following listing gives an introduction to the phylogenetic classification of the flowering plants that has emerged in recent decades, and which is based on nucleic acid sequences as well as morphological and developmental data. This listing emphasizes temperate families of the Northern Hemisphere and is meant as an overview with examples of Oregon native plants. It includes many exotic genera that are grown in Oregon as ornamentals plus other plants of interest worldwide. The genera that are Oregon natives are printed in a blue font. Genera that are exotics are shown in black, however genera in blue may also contain non-native species. Names separated by a slash are alternatives or else the nomenclature is in flux. When several genera have the same common name, the names are separated by commas. The order of the family names is from the linear listing of families in the APG III report.

Species of Epuraea currently known from New Zealand were described previously by WHITE (1846), REITTER (1877), SHARP (1878) and BROUN (1880), but some valid names were neglected by many subsequent authors, such that some problems in their nomenclature and systematics remained unresolved.

The insects were sieved out after 24 hours from each 10 litres of raffia palm. Gas chromatography was used to analyse the raffia palm wine after 24 hours. The daily collection of the insects lasted for 28 days between February and March, 2008. The results showed that as the number of days increased the concentration of glucose and fructose decreased with alcoholic content increasing at varying pH and temperature. A total of eight insect species made up of seven genera represented by seven families – Formicidea, Apidae, Drosophilidae, Sarcophagidae, Calliphoridae, Nitidulidae and Curculronidae were obtained. There was a preponderance in the collection of Camponotus maculatus, Maycodrosophylla sp. and Lepidoptera larvae in all the site with C. acvapimensis and Apis mellifera L. collected in fairly large numbers from all the sites (villages). There was also preponderance in the collection of Diptera larvae, even though they were collected from only one village Ide.

Shahidul Islam1 Received: 25 November 2018 /Accepted: 28 May 2019 /Published online: 14 June 2019 # Springer Science+Business Media, LLC, part of Springer Nature 2019 Abstract Neurodegenerative diseases, such as Alzheimer’s disease have been recognized as one of the microvascular complications of type 2 diabetes (T2D). In this study, the effect of T2D on neuronal integrity and elemental distribution in the cerebellar cortex, as well as the therapeutic effect of Raffia Palm (Raphia hookeri) wine (RPW) were investigated in male albino rats. T2D was induced in 4 groups of rats using fructose and streptozotocin. One group served as negative control which was administered water, the second and third group were administered 150 and 300 mg/kg bodyweight of RPW, while the fourth was administered metformin (200 mg/kg bodyweight). Two other groups of normal rats were administered distilled water (control) and of RPW (300 mg/kg bodyweight). The rats were sacrificed after 5 weeks of treatment, and brains were collected. The cerebellum was removed, and several parts analyzed by immunochemistry, histology and scanning electron microscopy (SEM). Remaining brain tissues were used to analyze for the oxidative stress biomarkers and acetylcholinesterase activity. These analyses revealed oxidative damage with concomitantly increased acetylcholinesterase activity and upregulation of Nrf2 expression in the diabetic brain cerebellar cortexes.
