Abstract

ABSTRACT The preparation of acetyl ascorbate by acetylation without solvent and catalyst has been carried out. The preparation of acetyl ascorbate is carried out by reacting ascorbic acid with anhydrous acetic acid using a 1:1 mole ratio without solvent and catalyst. The acetylation reaction was carried out using the reflux method at 700C for 5 hours. The result of acetyl ascorbate acetylation is a yellow powder with a yield percentage of 71.8182%. The functional groups of the synthesized compound in the form of acetyl ascorbate were analyzed using a FT-IR spectrophotometer. The FT-IR analysis results show the functional groups OH, CH sp3, C=C, C=O ester and C-O-C ester. Based on these results it can be seen that acetyl ascorbate has been formed.

Abstract

Research about the isolation of chemical active compounds antioxidants from ethyl acetate fraction of betel leaf forest (Piper aduncum L.) have been done. This research aimed to determine the type of secondary metabolites that contained in ethyl acetate fraction and the value of antioxidant activity as well as the structure that contained in ethyl acetate fraction. The test results of phytochemical showed that the secondary metabolites in ethanol extract are alkaloids, steroids and triterpenoids. The inhibitory concentration 50% (IC50) value that shown in the fraction Piper aduncum ethyl acetate-4-3 (PAEA-4-3) is 132.84 ppm. Fraction of PAEA-4-3 that have high levels of antioxidant activity was analyzed using a spectrophotometer Ultra Violet-Visible (UV-Vis), Infrared Fourier-Transform (FTIR) and Nuclear Magnetic Resonance (NMR) proton and carbon. The result analysis of PAEA-4-3 isolates showed the compound as 2,3-dimethoxy-metilanaoksi-benzene.

Abstract

Penelitian inibertujuan untuk mengetahui toksisitas dan sifat alelopati ekstrak alang-alang (Imperata cylindrica) terhadap perkecambahan biji padi (Oriza sativa). Sampel kering akar alang-alang dari Kutai Lama dimaserasi menggunakan pelarut etanol dan di fraksinasi menggunakan pelarut n-heksana dan etil asetat. Sampel kemudian di Skrining fitokimia dan uji toksistas dengan metode (Brini Shrimp Lethality Test) BSLT. Fraksi yang menunjukkan nilai LC50 paling rendah kemudian diuji sifat alelopati dan dianalisis dengan GC-MS. Hasil uji skrining fitokimia menunjukkan adanya kandungan alkaloid, triterpenoid dan fenol. Hasil uji toksisitas dengan metode (Brini Shrimp Lethality Test) BSLT menunjukkan bahwa fraksi etanol memiliki toksisitas tertinggi pada larva udang dengan nilai LC50 sebesar 647,5364 ppm. Uji senyawa alelopati dari ekstrak alang-alang dilakukan pada biji padi (Oriza sativa) memiliki pengaruh nyata terhadap perkecambahan biji padi. Analisa kandungan senyawa kimia pada fraksi etanol dari akar alang-alang menghasilkan dua puncak komponen senyawa pada spektra massa yang ditunjukkan dari hasil GC-MS yaitu fenol dan tetradecamethylcycloheptasiloxane.
