Abstract

Analisis komparatif dari asam lemak pengobatan sampel menggunakan yang segar, digoreng, direbus dan goreng cumi telah dilakukan. Sampel cumi diekstraksi dengan petroleum eter mengakibatkan berbagai tingkat lemak, 4,47%  dari  yang  segar,  12,86%  dari  yang  digoreng,  12,24%  dari  direbus-goreng. Minyak  ditransesterifkasi dengan BF3-metanol selama 3 jam dan dianalisis dengan GC-MS, diperoleh 10-12 jenis asam lemak yaitu,C12: 0, C15: 0, C16: 0, C17: 0, C18: 0, C20: 0, C16 : 1 Δ9, C18: 1 Δ9, C18: 2 Δ9,12,C20: 4 Δ5,8,11,14, C24: 1 Δ15, C27:1 Δ5. Penyajian MUFA dan PUFA pada cumi-cumi segar, berbeda secara signifkan dengan percobaan goreng dan rebus-goreng

Abstract

Characterization of Myristicin isolated from nutmeg oil has been done. The study was started by isolating the nutmeg oil from the nutmeg using steam distillation for 8 hours, yield 2.40% of nutmeg oil. The isolation of myristicin from nutmeg oil by fractional distillation under reduced pressure, yield 8.02% of myristicin with 100% of purity. The purity was determinated using GC and the structure elucidation was analyzed by FTIR, 1H-NMR, and MS spectromecters

Abstract

Isolation of eugenol from clove oil and synthesis of eugenyl acetate from eugenol had been concluded. Extraction of clove oil from clove flower by using petrolium benzene with sohxlet extraction method so obtained 33.82%. The isolation of eugenol with NaOH yields 32.07% with purity 97.47% by gas chromatography. Esterification of eugenol with acetate anhydride and sodium acetate anhydride as catalyst yields eugenyl acetate 51,67% with purity 98.38%. Elucidation of these structures were analyzed by FTIR, 1H-NMR and MS spectrofotometry

Abstract

A healthy simple natural drink is introduced based on a deep physical research investigation into insulin leaf (Tithonia diversifolia (Hemsley) A. Gray (Asteraceae)). Such drink was simply fabricated using two steps process of heating and cooling, and then exposed according to 2 main unique physical properties of optical and electrical behaviors. It was well-known that Tithonia diversifolia (Hemsley) A. Gray (Asteraceae)) had been very attractive in the east Africa continent and in the most of areas in Asia continent, as well as in Indonesia country of over 14,480 islands as Daun Kembang bulan because of its various biological and chemical properties to sustain human being life on earth. In present paper, our findings are focused on the unique physical characters sustained with a simple theoretical model to explain the interplay quantity of mechanical vibration of 2 main compounds of Tagitinine A (C19H28O7) and Tagitinine C or artemisinic acid (C15H22O2) identified using HPLC in such natural healthy drink produced by our Herbal Blessing standard products in nanotechnology research center and innovative creation (PPNRI) at Pattimura university. Such interesting finding suggests that the interactive vibration only involved about ~23.763 % mass of the total conserved mass

Abstract

In these studies, Pyridinium chlorochromate-Alumina was used for oxidation of secondary alcohols (safryl alcohol and methyleugenyl alcohol) to ketone.  The oxidation of safryl alcohol with PCC-Al2O3 followed by purification by potassium bisulfite yields safryl ketone (62,92%). The oxidation of methyleugenyl alcohol with PCC-Al2O3, followed by purification by potassium bisulfite  yields methyleugenyl ketone (68,04%). The elucidation of these products was analyzed by FTIR, 1H-NMR and MS.

Abstract

Synthesis of analog L-α-metil-Dopa from eugenol has been achieved through conversion of allyl group to ketone, followed by reaction with NH3 and KCN and by hydrolisis. The addition reaction of methyleugenol with formic acid yield methyleugenyl formate (60,69%). The hydrolis of methyileugenylformate with KOH in aqaueous-ethanolic solution produced methyleugenyl alcohol (73,68%). The oxidation of methyleugenyl alcohol with PCC yield methyleugenyl ketone (67,71%). The reaction of methyleugenyl ketone with NH3 and KCN yield D,L-α-amino-α-(3,4-dimetoxybenzyl) propionitril (84,14%). The hydrolisis of D,L-α-amino-α-(3,4-dimetoxybenzyl) propionitril with concentrated hydrochloric acid gave Analog L-α-metil-Dopa as a main target (91,98%). The structure elucidation of these products were analyzed by FTIR, 1H-NMR, 13C-NMR and MS

Abstract

Synthesis of safryl ketone from safrole has been achieved through conversion of allyl group to secondary alcohol, followed by oxidation with PCC-Al2O3. The oxymecuration-demercuration reaction of safrole with HgSO4-NaBH4 yields safryl alcohol (66.38%) and the oxidation of safryl alcohol with PCC-Al2O3 yields safryl ketone (62.92%). The structure elucidation of these products was conducted using Fourier Transformed Infra Red Spectroscopy (FTIR), Proton-Nuclear Magnetic Resonance (1H-NMR) and Mass Spectroscopy (MS).
