| 8311 | 2018 Thesis | Chemical constituents from the calyces of Hibiscus Sabdariffa Linn and its a-Glucosidase inhibitory activity Nadzirah Mohd Jauah The purpose of this study was to investigate the chemical compounds from the calyces of Hibiscus sabdariffa Linn. and their α-glucosidase inhibitory activity. Samples were collected from Balik Pulau, Pulau Pinang. The total of three kilogram of samples were air dried at room temperature, grinded and serially extracted by solid liquid extraction technique using hexane, dichloromethane, methanol, ethanol and water. Compounds were isolated and purified by several chromatographic techniques. Their structures were elucidated with spectroscopic methods including Nuclear Magnetic Resonance (1D-NMR and 2D-NMR), Liquid Chromatography-Mass (LCMS) spectrometry, infrared (IR) spectroscopy, ultraviolet (UV) spectroscopy and compared with data reported in the literature. The α-glucosidase inhibitory activity on the crude extracts and pure compounds was conducted using α -glucosidase inhibitory assay. The finding of this phytochemical study has led to the isolation of seven pure compounds namely s..... 755 hits |

| 8313 | 2018 Thesis | Effectiveness of using circle geometry board strategy in learning circle geometry towards form four students performance Reena Nancy Stephen Benjamin This study aims to determine the effectiveness of Circle Geometry Board (CG-Board) strategy in learning Circle Geometry towards Form Four students’ performance. This study also examined students’ Van Hiele’s level of Geometric Thought. The pre-test and post-test non-equivalent control group quasi-experimental designed was used. The selection of subjects was conducted by cluster probability sampling involving 52 Form Four students at a school in Hilir Perak district. The subjects were divided equally into control and treatment group. A three-week intervention was carried out. The instruments used are prior knowledge test, a set of pre-test and post-test on Circle Geometry and observation checklist. Descriptive analysis was used to describe students’ performance in the topic while independent t-test was used to determine the differences between the teaching strategies. The result showed that there was an increase in students’ performance in both control and treatment groups. Ba..... 1343 hits |
