Purple Sweet Potato

West Java is one of the regions in Indonesia that produces large numbers of mango, banana, and purple sweet potato. After harvesting, these commodities will undergo physical, chemical, and physiological changes so that further post-harvest processing is needed. One of the post-harvest processing that can be done is fermentation. Fermenting mango, banana, and purple sweet potato into wine is a simple and efficient method that can increase the economic value of the product. Wine is an alcoholic beverage made from grapes; however, any fruit and tuber could be used for wine-making. The article reviews the potential of mango, banana, and purple sweet potato for wine production, the microbes involved, and pretreatments of mango, banana, and purple sweet potato.

<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

This study aims to determine the effect giving of ethylacetate fraction of leather  purple sweet potato (Ipomoea batatas (L.) Lam, on levels of malondialdehyde (MDA) serum in mice hyperglicemia were induced with streptozocin dose of 50 mg/kgBW. Mice were divided into 5 groups, each group consisting of 3 tails, group I is a negative control, group II is a positive control, group III,IV and V is given ethylacetate fraction a dose of 100 mg/kgBW, 300 mg/kgBW, and 600 mg/kgBW. Ethyl Acetate Fraction leather purple sweet potato given orally for 15 days after the animal is declared hyperglicemia and measurement of blood glucose levels on 5, 10, and 15 day after giving test preparation in animal experiments. On the 16 day throughout the mice were taken serum levels measured malondialdehid. The statistical analysis results showed that giving of ethyl acetate fraction of leather purple sweet potato at a dose of 100 mg/kgBW, 300 mg/kgBW, and 600 mg/kgBW can lower blood glucose levels in mice hyperglycemia significantly (p<0.05). Malondialdehid levels on average in each group is 1.35 nmol/ml, 3.00 nmol/ml, 2.72 nmol/ml, 2.20 nmol/ml and 2.61 nmol/ml, the results of statistical analysis showed a decrease in melondialdehid serum levels were significantly (p<0.05), where a dose of 300 mg/kgBW is an effective dose for lowering blood glucose levels followed by decreased levels of malondialdehid which give effect approaching negative control.

The browning of white adipocytes, which transforms energy-storing white adipocytes to heat-producing beige adipocytes, is considered a strategy against metabolic diseases. Several dietary compounds, such as anthocyanins, flavonoids, and phenolic acids, induce a brown adipocyte-like phenotype in white adipocytes. In this study, we demonstrated that purple sweet potato (Ipomoea batatas) extract (PSP) exhibited potent radical scavenging activity. In addition, PSP was found to contain large amounts of phenolic, flavonoid, and anthocyanin compounds; the amount of these compounds was affected by fermentation. Functionally, PSP-induced adipose browning in high-fat-diet (HFD)-induced obese mice. The administration of PSP significantly suppressed the body weight gain and abnormal expansion of white adipose tissues in the obese mice. The expression of adipose browning-related genes was higher in the inguinal white adipose tissues from the PSP-treated mice than those in the HFD-fed mice. Moreover, PSP-treated 3T3-L1 adipocytes formed multilocular lipid droplets, similar to those formed in the 3T3-L1 adipocytes treated with a browning induction cocktail. The PSP-treated cells had an increased expression level of mitochondria and lipolysis-related genes. The browning effects of PSP were enhanced by fermentation with Lactobacillus. This study, to our knowledge, is the first to identify a new mechanism to increase the antiobesity effects of PSP by inducing adipocyte browning of adipocytes.
