Abstract

Abstrak (ina) :Suatu disakarida, sukrosa telah diisolasi dari kulit batang Alangium kurzii Craib. Metode isolasi yang dilakukan ialah kulit batangAlangium kurzii Craib kering diekstraksi dengan methanol. Selanjutnya methanol dipartisi dengan aseton. Residu tidak larut dalam aseton dikromatografi kolom dengan fasa diam silika gel dan berbagai fasa gerak diperoleh senyawa murni sukrosa sebanyak 340 mg. Penentuan struktur sukrosa tersebut dilakukan dengan cara membandingkan data spektroskopinya dengan data literatur. Rumus molekul C12H22O11 diperoleh dari gabungan data spektrum Distortionless Enhancement by Polirization Transfer (DEPT) pada resonanis magnetik inti karbon (RMI 13C) dan spectrum massa. Spektrumk resonansi magnetic inti proton (RMI-1H) menunjukkan adanya satu proton anomerik pada pergeseran kimia (?) 6,20 ppm. Spektrum RMI-13C menunjukkan dua karbon anomerik pada ? 105,9 dan 93,6 ppm. Spektrum DEPT menunjukkan adanya sinyal-sinyal sebagai berikut: tiga metilen pada ? 64,9 (C-6’);  63,0  (C-1’); 62,5 (C-6), delpan metin pada ? 93,6 (C-1); 84,4 (C-5’); 80,0 (C-3’); 75,7 (C4’); 75,2 (C-3); 74,9 (C-5); 73,5 (C-2); 71,9 (C-4); dan satu karbon kuartener pada ? 105,9 ppm (C-2’).

Abstract

The leaves and fruits of Indonesian Syzygium spp such as white pakoba, red pakoba and bombongan have been extracted by ethanol. The ethanolic extract was partitioned with polar solvent gradient using n-hexane, ethyl acetate and n-butanol repeatedly. Each fraction was tested for antidiabetic activity and exhibited varying degrees of antidiabetic activity when tested with α-glucosidase method. Antidiabetic test indicated that the ethyl acetate and butanol fractions of the leaves of pakoba white, red pakoba and bombongan has potential as a source of active compounds.

Abstract

Abstrak. Nasi Jaha merupakan salah satu panganan tradisional Sulawesi Utara sudah lama dikenal oleh masyarakat luas termasuk turis manca Negara.  Bahkan menjadi salah satu kue atau panganan tradisional yang pasarannya mampu menembus berbagai usaha kuliner dan restorant serta perhotelan. Walaupun demikian produksi usaha panganan tradisional Mitra “Tante Jeni” masih menghadapi masalah  yaitu (1) kurangnya pengetahuan dan keterampilan pengolahan  Nasi Jaha lebih berkualitas dan higienis, (2) tidak tersedia fasilitas pengemasan yang higienis. (3) sistem pemasaran masih tradisional dan, (4) belum ada pembukuan untuk pencatatan keuangan dan produksi yang standar, (5) rendah produksi dan tingkat pendapatan mitra. Metode pendekatan yang digunakan adalah kombinasi  Rapid Rural Appraisial (RRA) dan  Participatory Rural Appraisal (PRA), dimana permasalahan masyarakat (mitra) dikaji dan didalami oleh tim dan selanjutnya dianalisis dan dikaji bersama mitra dan tim pelaksana, sehingga langkah penyelesaian masalah merupakan buah pemikiran dan kesepakatan bersama tim pelaksana dengan mitra. Hasil yang diperoleh yaitu (1) terfasilitasi upaya peningkatan sumberdaya manusia melalui peningkatan pengetahuan dan keterampilan pengolahan terutama pengemasan Nasi Jaha yang berkualitas dengan menggunakan Vacuum Sealer, (2) terfasilitasi upaya menghadirkan satu unit Vacuum Sealer untuk pengemasan Nasi Jaha yang sehat dan higienis, (3) Adanya peningkatan pengetahuan dan keterampilan pemasaran dan pengelolaan keuangan, (4) terjadi peningkatan produksi dan pendapatan mitra.Kata Kunci: Nasi Jaha, kuliner, panganan tradisional, vacuum sealer, produksi

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)
