A preliminary study to determine the group of compound contained in the ethanolic extract of mahagony (Swietenia mahagoni L. Jacq.) seeds and its inhibitory activity to a-glucosidase enzyme has been done. The information from this study will be used in the further investigation about the specific constituents related to the bioactivity. The seed was grounded and then extracted with ethanol by maceration technique. The crude extract was separated with liquid-liquid extraction by using n-hexane, ethyl acetate, and methanol as the solvents. The best eluent for isolation, chloroform:ethanol (1:1), was determined by thin layer chromatography while alumina as stationary phase. The isolation step with column chromatography gave two types of isolates, yellow and colorless isolate. In order to get information about the compound, the crude extract was subjected to phytochemical assignment and the isolate with the better activity was analyzed by infrared spectroscopy. The inhibitory activity for the yellow isolate with IC50 as 19.345 ppm was better than the colorless isolate. Therefore, the IR spectroscopy assay was subjected to the yellow isolate. Based on the comparison IR spectra with literatures, it has suggested that the yellow isolate contains tetranortriterpenoid or limonoid group.Keywords: Swietenia mahagoni L.

Odonata, which consists of true dragonflies and damselflies, is considerably understudied in Sumatra, especially in West Sumatra region. While the campus area of Andalas University in Limau Manis provides many suitable habitats for dragonflies and damselflies, the least has been done in learning these organisms. In this paper, we intend to conduct the inventory of Odonata in Limau Manis area by using photography approach (by taking decent pictures only, without sampling the animal). After spending 14 days of data collection which spanned from October 2017 until February 2018), we listed 27 Odonata species. Of which, 11 species belong to four families under suborder Zygoptera and 16 species grouped into four families under suborder Anisoptera. Libellulidae is a family under Anisoptera that was found with most species members. Photography approach promises an immense help in doing species inventory for this animal group for its reliability in determining species identification without harming species’ population.Keywords: damselflies, dragonflies, Libellulidae, Limau Manis area, photography approach
