Uji Aktivitas Antidiabetes Dengan Metode Penghambatan Enzim α-Glukosidase dan Karakterisasi Kandungan Senyawa Aktif pada Fraksi Metanol dan Kloroform Daun Lavetar (Wedelia biflora (L).DC) Asal Biak
Salah satu jenis tanaman yang dijadikan sebagai obat tradisional adalah tumbuhan Lavetar (W. biflora) yang di manfaatkan oleh masyarakat Biak sebagai obat untuk mengobati penyakit diabetes. Penemuan sumber penghambat α-glukosidase sangat bermanfaat dalam upaya pengembangan obat herbal yang lebih efektif bagi penderita diabetes. Penelitian ini bertujuan untuk menentukan aktivitas antidiabetes fraksi metanol dan fraksi kloroform daun Lavetar dengan metode aktivitas penghambatan enzim α-glukosidase serta menentukan kandungan senyawa aktif dengan menggunakan GCMS. Hasil skrining fitokimia menunjukkan bahwa senyawa aktif pada fraksi metanol adalah flavonoid dan tannin sedangkan fraksi kloroform …
UJI AKTIVITAS ANTIBAKTERI DAN SKRINING FITOKIMIA EKSTRAK HEKSANA, ETIL ASETAT DAN METANOL TUMBUHAN SURUHAN (Peperomia pellucida L. Kunth)
Antibacterial activity test and screening of phytochemical of extract hexane, ethyl acetate and methanol have been carried out. The extraction of the P.pellucida plants was carried out by the maceration method in stages based on the polarity of the solvent. Analysis of chemical compounds done with phytochemical screening test. Based on the identification of chemical compounds by phytochemical screening, hexane and ethyl acetate extract has been detected only in the presence of flavonoid compounds with moderate categories. Methanol extract contains high-grade alkaloids and moderate flavonoid and tannin compounds. Antibacterial test using disffusion methods suggest that ethyl acetate and me…
ANALISIS KADAR BIOETANOL HASIL FERMENTASI DARI NIRA NIPAH (Nypa fruticans wurmb) ASAL PAPUA
This study aims to analyze the ethanol content in fermented palm juice.This research includes the preparation of raw materials, fermentation, distillation and distillation products analyzed by gas chromatography method. Fermentation is carried out for 2, 5, 7 days, the highest level of bioethanol produced is then selected for distillation. Levels the highest fermentation process is on the 5th day with a level of 18%. Got results the final distillation is 117 mL with a level of 94% of the initial volume of 4.2 L fermentation based on measurements using an alcoholmeter while the analysis by gas chromatography yielded 93.9% levels. The density of bioethanol is 0.8232 gr / mL. The results of th…
