Abstract

This study aims to determine the yield, toxicity, and toxic concentration of crude extracts of ethanol, n-hexane fraction extract, ethyl acetate fraction extract and n-butanol fractions extract pare leaf (Momordica charantiaL.) larvae Culex pipiens. The method used to determine the toxicity of extract larvasida test larvae Culex pipiens to obtain the LC99 values obtained using the analysis of Reed and Muench. Extraction and fractionation processis known to yield a ethanol crude extract obtained 8.86%, n-hexane fraction extract of 1%, ethyl acetate fraction extract 1.80% and n-butanol fractions extract of 0.80% and the toxicity obtained test results that pare leaf (Momordica charantia L.) have the potential toxicity larvae larvae of Culex pipiens as indicated by the value by Lethality Concrentation 99 % (LC99) in the crude extract ethanol 7416.52  ppm, n-hexane fraction extract of 2564.48 ppm, ethyl acetate fraction extract 2702.09 ppm and n-butanol fractions extract of 2665.63 ppm. Keywords: Pare leaf (Momordica charantia L.), toxicity, larvae Culex pipiens

Abstract

Estrogen deficiency causes various health problems in postmenopausal women, including neurodegenerative disease. Phytoestrogens emerged as a group of compounds that can replace the estrogen function in the body, and prevent the neurodegenerative disease to occur. Semanggi (Marsilea crenata Presl.) is a typical plant in Surabaya, Indonesia, that contain phytoestrogens. The aim of this research was to determine the metabolite profile of n-hexane fraction of Semanggi leaves using UPLC-QToF-MS/MS, and then to predict the neuroprotective activity of compounds with in silico study using PyRX 0.8 software. The 100 ppm of n-hexane fraction of Semanggi leaves in DCM and methanol were injected 5 µl each into the UPLC-QToF-MS/MS, and then analyzed by Masslynx 4.1 software to determine the compounds. The compounds from metabolite profiling then prepared with SwissADME webtool and Avogadro 1.90.0 software, molecular docking was done using Autodock Vina and Biovia Discovery Studio Visualizer 2016 to 3OLS protein. Metabolite profiling process shows a total of 34 predictable compounds and 28 unknown compounds. From in silico study, it shows a total of 7 compounds that are predicted to have activities similar to estrogen. This result indicate that n-hexane fraction of Semanggi leaves has potential as a neuroprotective agent for treatment for postmenopausal women who experience estrogen deficiency.Keywords: Marsilea crenata Presl., phytoestrogens, metabolite profiling, in silico, neuroprotective
