Abstract

The phytochemical screening and antilitiasis assay have been done on the ethanolic extract of nusa indah putih leaf (Mussaenda pubescens). The screening phyticemical results showed that the leaves of nusa indah putih (M. pubescens) positively contain alkaloids and flavonoids. Antilitiasis assay results showed effectiveness in improving urolithiasis rats at doses of 300 mg / kg BW better in improving kidney compared to dose 150 mg / kg BW with a concentration of 1.8 ml / rat.

Abstract

The terminal alkynes hydration reaction on 17α-ethynylestradiol (1) with FeCl3 catalyst mediated by dichloromethane aims to determine the reaction products produced and to conduct a Markovnikov regiochemistry study through the proposed reaction mechanism. The reaction conditions were carried out at a temperature of 50oC (48 hours) and 60oC (19 hours), the separation of the reaction properties was carried out using Gravity Column Chromatography, and the reaction products were identification using by Proton Nuclear Magnetic Resonance (1H-NMR). Here we describe the process of the FeCl3 catalyst forming a coordination complex with the terminal alkyne, which is then addition by nucleophilic water following Markovnikov's regiochemistry to finally produce the product of a methyl ketone, 17α-acetylestradiol (6). The catalyst used is a cationic ligand coordinate, where Fe3+ is a Lewis acid and Cl3- acts as a ligand. The dichloromethane solvent used can also increase the reaction rate.

Abstract

The red pakoba (Syzygium sp.) is a plant originating from north sulawesi that is often used by local people as a basic ingridient of medicine. This research was conducted to isolate and identify glycoside compounds contained in the n-butanol fraction of red pakoba fruits (Syzygium sp.). The isolation process was carried out using the maceration method, for the separation and purification of compounds using Thin Layer Chromatography (TLC) and Gravity Column Chromatography and obtained F2.4 sub-fraction isolates with a sample weight of 4.5 mg. Identification of compound using Proton Nuclear Magnetic Resonance (NMR-1H) and Carbon Nuclear Magnetic Resonance (NMR-13C) tecniques. The result of identification of isolate F2.4 sub-fraction as flavonoid glycoside compounds with the proposed name 3-O-methyl-butyrate-6,7,3',4' tetrahydroxy-5-methoxy-8-methyl flavan with molecular formula (C22H25O8)

Abstract

Daun pare hutan (Momordica balsamina L) merupakan tanaman asli wilayah yang beriklim tropis yang tumbuh liar dan dimanfaatkan oleh masyarakat sebagai obat herbal. Penelitian ini dilakukan untuk mempelajari, senyawa metabolit sekunder yang terkandung dalam fraksi etil asetat daun pare hutan (momordica balsamina L.), dengan cara di isolasi dan di identifikasi. Proses isolasi dilakukan menggunakan metode maserasi, untuk pemisahan dan pemurnian senyawa menggunakan metode Kromatografi Lapis Tipis (KLT) dan Kromatografi Kolom Gravitasi sehingga diperoleh isolat (F1.6.1) dengan berat sampel 1,4 mg. Identifikasi senyawa mengunakan Nuclear Magnetic Resonance Proton (1H-NMR) dan Nuclear Magnetic Resonance Carbon (13C-NMR). Hasil identifikasi isolat ditentukan sebagai suatu senyawa carbinol dengan usulan nama struktur 2,2,3,3-tetramethylcyclohexane-1,1-diol dengan rumus molekul C10H18O2.
