<p>Liver is an organ with complex metabolism. When the liver is inflamed, cellular immunity will defend against inflammatory agents by stimulating immune cells to produce reactive oxygen species (ROS). Excessive ROS accumulation cause oxydative stress with increased  liver malondialdehyde (MDA) level. Some researches showed that purple sweet potato contain flavonoids (anthocyanins) that functioned as antioxydants. This study aimed to show the prophylactic effect of purple sweet potato extract to the liver MDA level of male Wistar rats induced by carrageenan.</p><p>This study used post-only control group method using 18 male Wistar rats divided into 3 groups: group of rats without treatment, group of rats induced by 0,1 ml of 1% carrageenan by intraplantar injection on day-8, and group of rats given with 872 mg/kgBW of purple sweet potato extract for 7 days and induced by 0,1 ml of 1% carrageenan. In the end of the study, the liver MDA levels were measured by Thio-Barbituric Acid method on each groups.</p><p>The results of One-Way ANOVA test showed there was no significant difference (p = 0,290) between group of rats without treatment (<em>x̅</em>= 207,50) and group of rats induced by carrageenan (<em>x̅</em>=233,17). Then, there is no significant difference (p = 0.978) between group of rats induced by carrageenan and group of rats given with prophylactic purple sweet potato extract and induced by carrageenan (<em>x̅</em>= 232,50).</p><p>The conclusion of this study is giving intraplantar injection of carrageenan can increase liver MDA level insignificantly and giving prophylactic purple sweet potato extract has an effect to decrease the liver MDA level of rats induced by carragenan insignificantly because it contains anthocyanins as antioxidants.</p><p> </p><strong>Keywords: </strong>Liver, <em>Ipomoea batatas</em> L., Malondialdehyde, Anthocyanins

Retnati, Andriani MAM, Fauza G. 2009. The influence of addition of various sweet potatoes (Ipomea batatas) extract to total count of cells and antioxidant activity in yogurt. Biofarmasi 7: 68-76. The aim of this research was to determine the influence of addition of various sweet potatoes extract to the total count of cells and the antioxidant activity in yogurt. Yogurt was made from fresh milk, skim milk, white sweet potato, orange sweet potato, purple sweet potato, and pure culture of Streptococcus thermophilus 0040 and Lactobacillus bulgaricus 0041 in straight MRS agar. Fresh milk, skim milk powder (5%, b/v), and sweet potato extract (10%, v/v) was pasteurized at 90oC for 15 minutes, cooled to the temperature between 40-45oC, inoculated with 2.5% S. thermophilus and L. bulgaricus with a proportion of 1.4:1, and then incubated at a temperature of 40oC for 15 hours. Yogurt without an addition of sweet potato extract was used as control. The parameters measured in this experiment were the total count of cells with TPC (Total Plate Count) method and the antioxidant activity with DPPH (2,2- diphenyl-1-picrylhydrazyl) method. Samples were taken at one hour interval to examine the total count of cells, while the antioxidant activity was collected at three hours interval. The result of each analysis was plotted into graphics which describing the relation of total bacteria and antioxidant activity with fermentation time. ANOVA was employed to analyze the data. If there was a significant difference, it should be followed by Duncan Multiple Range Test (DMRT) at a significance level α=0.05. The result of this research showed that the addition of various sweet potatoes extracts increased the total count of cells and the antioxidant activity in yogurt. The total count of cells showed no significant different for each sample, it meant that the different colors in sweet potato did not influence the total count of cells. However, yogurt with orange and purple sweet potato extract addition had a significant difference on the antioxidant activity with control and yogurt with white sweet potato extract. In conclusion, the difference colors in sweet potato influenced in the antioxidant activity in yogurt significantly. Sweet potato is potential for milk substitute in yogurt production due to oligosaccharide content and antioxidant activity.

Tapai is one of the typical Indonesian fermented products. This research utilized Lactobacillus plantarum 1 RN2-53 and natural dyes made from plants in the production of cassava tapai. The objectives of this research were to improve the quality of probiotic cassava tapai and to obtain the chemical, microbiological and sensory characteristics of the cassava tapai. Natural dyes used were purple sweet potato extract, red dragon fruit extract and narrow-leaf pleomele extract. The results showed that cassava tapai made with the addition of Lactobacillus plantarum 1 RN2-53 and the addition of natural dyes from plants had different chemical and microbiological characteristics. Tapai made with the addition of red dragon fruit extract generally had a lower pH value and a higher total titrated acid compared to tapai made with the addition of purple sweet potato extract and narrow-leaf pleomele extract, but the alcohol content of tapai made with the addition of purple sweet potatoes extract was higher than the others. The number of lactic acid bacteria was around 109 and had met the probiotic food criteria.

This study was undertaken to analyze the quality of goat milk based cheese particularly its potential high antioxidant content through fortification of goat milk with purple sweet potato extract. A completely randomized design was used to determine the characterization of goat milk based cheese quality through five levels i.e. 0% (A); 2% (B); 4% (C); 6% (D) and 8% w/v (E) of purple sweet potato extract fortification in goat milk. The results showed that the increased level of fortification by purple sweet potato extract in goat milk based cheese significantly increased the pH value of the cheese (P<0.05) where the highest pH was 6.20 at the level of 4%  w/v. Meanwhile, the yield and total of cheese acid were not affected by the fortification. The content of cheese protein significantly decreased (P<0.05) by the increasing level of fortification by purple sweet potato in goat milk. Goat milk-based cheese on the E treatment contained the lowest protein (19.42%). Functional potency of the cheese increased significantly (P<0.05) when the level of fortification was increased. The highest antioxidant content in goat milk based cheese was 114.47 mg/L. GAEAC at 8% w/v level. In conclusion, by increasing fortified goat milk by purple sweet potato extract up to 8% w/v was able to potentially produce cheese containing a high antioxidant.
