Abstract

Sargassum polycystum is one species of the brown algae class (Phaeophyceae). Brown algae that grows and spreads in almost all Indonesian sea, and has been known to contain various bioactive compounds that are useful in the health field. The objectives of this study were to determine the effect of solvent-type composition on the resulting would compound content of phenol, ?-tocopherol, and carotenoid extract of Sargassum polycystum, and to determine the ratio of solvent type that obtain the best of Sargassum polycystum extract. This experiment used a Randomized Block Design (RBD) with 7 treatment of ethanol and acetone (v/v) solvents, (0 : 10), (1 : 9), (3 : 7), (5 : 5), (7 : 3), (9 : 1), (10 : 0). Furthermore, the treatment was grouped into 3 based on implementation time, so that obtained 21 units of experiments. The results showed that the ratio of solvent type was very significant (P<0,01) to all observed variables is rendement, total phenol, ?-tocopherol content, and total carotenoid. The effect treatment to the ratio of ethanol solvent : acetone (1: 9) v/v with 21.06 dielectric constant resulted in the best bioactive content of Sargassum polycystum extract with yield of 2,61%, total phenol 2,334 mgGAE/100g, ?-tocopherol 6,724 mg/100g, and total carotenoid 0,342%. Key words: Sargassum polycystum, bioactive compounds, ethanol, aceton, extraction.

Abstract

Sargassum polycystum is one type of brown seaweed (Phaeopychae) which contains various pigmentcontent such as beta carotene, chlorophyll a and b, and fucoxanthin. The pigment content of Sargassum hasmany potential benefits in both health and industry. The purpose of this study was to determine the effect ofethanol solvent concentration and maceration time on the natural dye characteristics of Sargassum polycystumextract, to determine the best solvent concentration and maceration duration in producing natural dyes fromSargassum polycystum extract. The experiments in this study used Factorial Randomized Block Design (RAK)with two factors. The first factor was the concentration of ethanol solvent consisting of 3 levels, ie 75%, 85%,and 95%. The second factor is the duration of maceration consisting of three levels, ie 12 hours, 24 hours and 36hours. The variables analyzed were rendement, chlorophyll a, b and total chlorophyll and color intensity (L *, a*, b *). The results showed that the concentration of ethanol solvent and maceration time had significant effecton all the variables tested. The interaction between ethanol concentration and maceration durations hadsignificantly effect on chlorophyll content of Sargassum polycystum extract, significantly affecting the colorintensity of L *, and had no significant effect on color intensity a * and b *. The treatment of 95% ethanolsolvent concentration and 36 hours of maceration time produced the best characteristic with yield of extract2,21%, chlorophyll a 93,4 ppm, chlorophyll content b 206,9 ppm, total chlorophyll content 300,7 ppm, and colorintensity (L *) 4.41, (a *) -3.91, (b *) 38.06.Key words: Sargassum polycystum, solvent concentration, maceration time, natural dye.

Abstract

Dietary fiber with excellent fermentability can be categorized as prebiotics, one of which was green grass jelly. The objective of this research was to know the concentration of green grass leaf extract powder to stimulate the growth of Lactic Acid Bacteria (Lactobacillus casei subsp. rhamnosus). In vitro experiments were performed in laboratory with a concentration treatment of green grass leaf powder and glucose as a control. The medium used was yeast-peptone medium added with 1% glucose, 0% green grass leaf extract powder, 0.1% green grass leaf extract powder, 0.2% green grass leaf extract powder, 0.3% green grass leaf extract powder, 0.4% green grass leaf extract powder, and 0.5% green grass leaf extract powder. Fermentation was carried out at 37oC with a fermentation time of 9 hours. The experimental results showed that the concentration of green grass leaf powder extract of 0.2% was the best, in performance to stimulating growth of LAB. This concentration of the extract was the critical concentration, since the process of medium solidification was occured at the extract concentration of more than 0.2%. Keywords: Lactobacillus casei subsp. rhamnosus, green grass jelly, prebiotic.
