Abstract

Tanaman miana (Coleous scutellarioides) merupakan salah satu tanaman tropis yang mengandung antosianin yang dapat berpotensi sebagai zat warna alami. Pigmen antosianin memiliki stabilitas yang rendah, namun dapat ditingkatkan dengan mikroenkapsulasi. Tujuan dari penelitian ini adalah menentukan kinetika degradasi serbuk antosianin daun miana hasil mikroenkapsulasi. Mikroenkapsulasi dilakukan dengan menambahkan maltodekstrin berbagai konsentrasi (8, 10, 12, dan 14% b/v) dalam ekstrak daun miana. Daun miana diekstrak menggunakan pelarut asam tartarat 2% (b/v). Serbuk antosianin disimpan dalam inkubator pada suhu 25, 35, dan 45°C. Hasil penelitian menunjukkan bahwa reaksi degradasi antosianin mengikuti orde 2. Kinetika degradasi yang paling stabil adalah pada penambahan maltodekstrin 8% yang ditunjukkan dengan konstanta laju degradasi, waktu paruh, dan energi aktivasi.

Abstract

The aims of this study were to compare the antioxidant activity and the total phenolic content of red sea weed (Gracilaria verrucosa L.) from extract of methanol, ethanol, acetone, chloroform and hexane; and the correlation between total phenolic content and the antioxidant activity of each extract; then to determine the chlorophyll a, chlorophyll b, and carotene content of each extract and their correlation with the free radical scavenging activity as well. The antioxidant activity were measured by free radical scavenging method with DPPH and by reducing power method with K4Fe(CN)6 as standard, whereas the total phenolic content was measured by Folin Ciocalteu method with gallic acid as standard. Chlorophyll a, chlorophyll b, and carotene were determined by spectrophotometric method based on Lambert-Beer law. The data of antioxidant activity and total phenolic content were statistically analyzed by Randomized Completely Block Design (RCBD) with five kinds of solvents as treatments and five replications. Honestly Significant Difference Test (HSDT) was used to compare the difference of treatments; whereas the chlorophyll a, chlorophyll b, and carotene content were not statistically analyzed since they were only supplement data. The results showed that the highest of the antioxidant activity by free radical scavenging method was found in acetone extract : 43.43% (BHT: 84.15%); whereas by reducing power method was found in chloroform extract : 0.1756 meq K4Fe(CN)6/g extract (BHT : 6.1767 meq K4Fe(CN)6/g extract); and the highest of the total phenolic content was also found in acetone extract : 45.29 mg /g extract. There were close correlation between phenolic content and antioxidant activity both by free radical scavenging method and by reducing power method with r (coefficient correlation) respectivelly 0.89 and 0.91.Chlorophyll a and carotene had also close correlation with the free radical scaveging activity, but not for chlorophyll b.Key words : antioxidant activity, free radical scavenging activity, reducing power, phenolic content, chlorophyll, carotene

Abstract

 Anthocyanins are red to purple pigments and one of potent safe and natural food colorants which possess superior antioxidant activity. However, the stability of anthocyanins depends on various factors, including structure and concentrations, pH, temperatures, light, co-pigment, ascorbic acid, enzymes, metal ions, sugars, protein, sulfur dioxide. The aims of this research were to evaluate the effects of sugar addition on the stability of anthocyanin of black mulberry under different fluorescent light intensities and to determine the appropriate concentration of sugar that could increase black mulberry (Morus nigra L.) anthocyanin stability. Fluorescent lamp at 3370, 4210, and 8820 lux (18, 23, and 32 watt, respectively) were used to illuminate black mulberry fruit extract (10.09 g/L) following 20, 40, 60% (w/v) of sugar addition. Determination of anthocyanin color stability in extract of black mulberry fruit was perfomed using degradation kinetics modeling to obtain the appropriate order. The concentration rate (k) and half life (t1/2) were then calculated based on subsequent order. The results showed that 20% sugar addition enhance the stability of black mulberry anthocyanin extract as compared to that of control (without sugar addition) as indicated by half life increment from 170.826 to 183.733 h. On the other hand, anthocyanin stability decreased to 166.618 and 146.235 h half life with further sugar addition to 40 and 60%, respectively. Therefore, 20% sugar addition to black mulberry extract could improve its anthocyanin stability.

Abstract

Batoko plum fruit (Flacourtia inermis, Roxb) is one of the plants that contains anthocyanins. The fruit has purplish red color and was thought to benefit health by reducing blood sugar levels, as anti-hyperten-sion agents or antioxidants. The aim of this research was to determine the total anthocyanin content and identify the type of anthocyanidin and anthocyanin of batoko plum fruit. The total anthocyanin content of batoko plum fruit which determined by differential pH method was 26.56±0.28 mg/100 g (w.b.) or 103.89±1.08 mg/100 g (d.b.). Based on the Rf value on TLC and the peak retention time in HPLC, it was confirmed that the anthocyanin was delfinidine. However, the wavelength maximum absorbance data of the TLC spot showed  the presence of cyanidine. These results were possibly caused by the use of too diluted extracts or the degradation of the anthocyanin during acid hydrolysis. Based on the Rf value on TLC and glucosidation pattern in UV-VIS spectrophotometer, it is suspected that cyanidine 3-glucoside and delfinidine 3-glucoside were present.

Abstract

Research on antioxidant activity, anthocyanin, and polyphenol contents of Java plum (Syzygium cumini) from several stages of maturity was carried out with three aims: to prove that the fruit contain anthocyanins; to compare antioxidant activity from three stages of fruit maturity; and to examine the possible correlation between maturation and antioxidant activity, anthocyanin and polyphenol contents. The fruit pulp was separated from the seed, frozen dried, and kept in freezer. The freezer dried fruit was extracted (macerated) with methanol-HCl 1% for overnight at 4ºC, and filtered with Whatman no 1 to obtain fruit extract. Anthocyanin-betacyanin testing was used to indicate that the fruit contain anthocyanin. Antioxidant activity test was conducted with ferri-thiocyanate method in linoleic acid emulsion system. Anthocyanin contents was determined with pH differential method, while its polyphenol with spectrophotometric method with Folin-CIocalteu reagent. The result showed that the fruit contained anthocyanin, ranging from 1,68 mg/g at young stage (green) to 29,39 mg/g at overripe stage (black), and showed that antioxidant activity was influenced by fruit maturity. With regard to fruit maturoty, the antioxidant activity of purple, red, adn green fruit were 64,75%, 62,42%, and 29,86% respectively; whereas that of BHT was 79,45%. It was noted that there were significant correlation between the level of anthocyanins, poluphenols, and the degrees of maturity. As the fruit maturity increased, the anthocyanin increased, but the polyphenol decreased. The fruit contained considerable amount of anthocyanins and had antioxidant activity that was influenced by stages of maturity. It was indicated that the more mature the fruit the higher anthocyanins and the lower polyphenols concentrations.
