Abstract

Abstract.The antioxidant activity from methanol extract of nutmeg leaves (Myristica fragrans Houtt) was performed using 2,2-diphenyl-1-picrylhydrazil (DPPH). Antioxidant assay using DPPH of the methanol extract at a concentration of 25 ppm, 50 ppm and 100 ppm, showed high antioxidant activity with IC50 = 36.31 ppm and Vitamin C showed antioxidant activity with IC50 = 3.657 ppm. The methanol extract of nutmeg leaves were partitioned with chloroform to obtain chloroform extract of the leaves with IC50 = 28.30 ppm. isolation of the active compounds from the chloroform  extract of the nutmeg leaf using column chromatography yielded 6 mix fractions MFMD 1, MFMD 2, MFMD 3, MFMD 4, MFMD 5 and MFMD 6. The test results of antioxidant activity in very strong category is fractions MFMD 4, MFMD 3, MFMD 2, MFMD 6 and MFMD 5 with IC50 of each are 26.590 ppm, 27.239 ppm, 29.639 ppm, 39.766 ppm and 55.436 ppm, while antioxidant activity in a weak catagory is fraction MFMD 1 with IC50 is 126.270 ppm. This shows that the fraction of the leaf has a better inhibitory activity, because some of the active compound contained in the fraction can synergize in inhibiting free radicals, so that the IC50 value of the fraction is stronger than the extract. Keywords: Antioxidant, chromathography, Nutmeg (Myristica fragransHoutt), methanol extract, leaves

Abstract

The essential oil of the nutmeg plant (Myristica fragrans Houtt) has been obtained from roots, bark, fruit, mace and seeds using Stahl steam distillation. Each essential oil have tested for antioxidant activity with DPPH. Antioxidant activity of essential oil from each nutmeg plant to DPPH with concentration 25, 50 and 100 ppm. Each essential oil did not show strong antioxidant activity but the result of nutmeg isolation had strong antioxidant activity with IC50 that was 80,555 ppm. Based on GC-MS analysis of essential oil of nutmeg isolate obtained myristicin compound with 96.52% area and time Retention 22.127. Myristicin is one of the main components of essential oils of nutmeg plants that play an important role as antioxidants. Keywords: Nutmeg plant (Myristica fragrans Houtt), Essential Oil, DPPH, Antioxidant radicalsREFERENCES Suryanti, Siti. 2014.

Abstract

Antimicrobial assay of n-hexane plant extracts against Escherichia coli and Staphylococcus aureus had been done. Extraction with n-Hexane of the flowers yielded 2,08% of extract, while leaves and stems yielded 3,21% and 2,19% of n-hexane extracts, respectively. The extracts showed different activity against both bioindicators. The leaves extracts showed the strongest activity indicated by wider diameters of inhibition zone, 19,7 mm against E. coli and 13,3 mm against S. aureus at 10% of the extracts’ concentration. At the same concentration (10%), the steam and flower extracts showed less inhibitory activities with  11,3 mm and 8,3 mm against E. coli, and 12,0 mm and 11,0 mm against S. aureus. At the lowest concentration of the extracts, the leaves extracts showed the strongest activity against E. coli (14,3 mm) while the steam extracts showed highest inhibitory activity against S. aureus ( 7,7 mm). Based on antimicrobial assay, it was suggested that the leaves extracts demonstrated strongest activity than other extracts. It was assumed that leaves extracts contained more secondary metabolite than flowers and steams, and the leaves have phenol compounds which are not present in other extracts.

Abstract

Antimicrobial activity of methanol extract from stem bark of Cinnamomum sintoc has been evaluated against Candida albicans, Staphylococcus aureus and Escherichia coli. The extraction of compound was carried out by maceration, then isolation by column chromatograph, which yielded five (5) subfractions (A-E). Activity against fungus C. albicans, S. aureus bacteria dan E. coli using agar dilution method in paper disk. Methanol extract was not potent against antifungal activity but shows antibacterial activity with medium category. Subfraction C showed that antibacterial activity against S. aureus and E. coli with weak category, but subfractions D and E did not show any activity.

Abstract

Abstract. It has tested the antioxidant activity of n-hexane extract respective roots, bark, fruit and seed crops of nutmeg against DPPH. Each extracted by maceration method with n-hexane. The extraction of each plant nutmeg with n-hexane extract obtained yield of n-hexane respectively 8,35%; 81,5%; 11,89% and 55,63%. The result of the antioxidant activity of n-hexane extract of each plant nutmeg against DPPH with a concentration of 25 ppm, 50 ppm and 100 ppm is obtained IC50, respectively, are 0,216 ppm, 63,755 ppm, 43,998 ppm and 11,599 ppm and positive control vitamin C ( IC50 = 3,657 ppm). Vitamin C is a standard compound is more often used than butyl for very high antioxidant activity. The antioxidant activity increases from high to low at the roots, seeds, fruits and bark of plants nutmeg in a row. Based on data GC-MS chemical components of each successive extracts of roots, bark, fruit and seeds are 41, 41, 44, 43 components of secondary metabolites. The main components of each part of the plant based on data from GC-MS are a 5-Octadecanoic acid, linalool, eugenol, myristicin, methoxyeugenol. The compounds are thought to play an active role in inhibiting free radicals from DPPH. n-Hexane extract nutmeg plant potential as an antioxidant. Keywords:Nutmeg (Myristica fragrans Houtt), n-hexane extract, Antioxidant, DPPH

Abstract

The interest in the development of edible and biodegradable films has increased because it is every day more evident that non degradable are doing much damage to the environment. In this research, edible films were based on blends of janeng starch in different proportions, added of palm oil or glycerol, which were used as plasticizers. The objective was to study the effect of two different plasticizers, palm oil and glycerol of edible film from janeng starch–chitosan on the mechanical properties and FTIR spectra. Increasing concentration of glycerol as plasticizer resulted tend to increased tensile strength and elongation at break. The tensile strength and elongation at break values for palm oil is higher than glycerol as plasticizer at the same concentration. FTIR spectra show the process of making edible film from janeng starch–chitosan with palm oil or glycerol as plasticizers are physically mixing in the presence of hydrogen interactions between chains.
