  Food with antioxidant is very important to reduce the radical activity can caused oxidative stress. Antioxidant react as scavenger to reduce the radical actions, polyphenols were the common antioxidant in some plants. Colored rice which have some pigment have contribution as antioxidant activity. Red and black pigment on the rice seeds which give color to colored rice were polyphenols. We identified the 1,1-Diphenyl-2-picrylhydrazyl (DPPH), radical scavenging activity, total polyphenol, anthocyanin and protein content of eighteen colored rice from West Sumatra Indonesia, nine red rice cultivar, six black rice cultivar and two white rice cultivar as control. We found that some of the colored rice were polished at various level. The aim of this study was to identifiy the antioxidant activity of colored rice include polished and non polished rice. The result showed that the non polished colored rice have higher antioxidant activity than white rice. A variety of red rice cultivar from Solok Selatan was the best cultivar among other with antioxidant activity 54.2% at concentration 0.25 mg/ml, total polyphenol content 31.3 mg/ml and protein content 7.9%.

  Background and Objective: A previous study showed that anthocyanins are present in Asian melastome fruit, java plum fruit rind and mangosteen fruit rind, as well as the juices from these fruits, but these juices impart different colors when added to "kolang-kaling" jam. This study was conducted to identify 3 types of anthocyanin, Pelargonidin-3-glucoside chloride, malvidin-3-5-diglucoside chloride and cyanidin-3-0-glucoside chloride, in Asian melastome fruit, java plum fruit rind, mangosteen fruit rind and in "kolang-kaling" jam made with juice from these fruits and rinds. Materials and Methdos: Pelargonidin, malvidin and cyanidin content in the fruits and rinds was analyzed using a Thermo Ultimate 3000 HPLC with a CD-C18, 3 μm Cadenza column at a column temperature of 35°C. Results: The fruits and rinds did not contain pelargonidin-3-glucoside chloride, whereas, malvidin-3-5-diglucoside chloride was found only in java plum fruit rind and cyanidin-3-0-glucoside chloride was present only in Asian melastome fruit. Conclusion: The cyanidin-3-0-glucoside chloride and malvidin-3-5-diglucoside chloride contents increased linearly with addition of increasing amounts of juices from these fruits or rinds during "kolang-kaling" jam production.

  Background and Objective: The addition of ‘jamblang’ peel could increase the beneficial properties of ‘Kolang-kaling’ jam, including antioxidant activity. This study was conducted to evaluate the effect of ‘jamblang’ peel and citric acid addition on the antioxidant activity of ‘Kolang-kaling’ jam. Materials and Methods: A factorial design with a completely randomized design that considered 2 factors was used. Factor A was addition of ‘jamblang’ peel, at four concentrations: A1 (10%), A2 (15%), A3 (20%) and A4 (25%) and factor B was the addition of citric acid at three concentrations: B1 (0.2 g), B2 (0.3 g) and B3 (0.4 g). ‘Kolang-kaling’ jam with the various additions was analyzed for total phenol and total anthocyanin content, as well as antioxidant activity (IC50). Results: The addition of ‘jamblang’ peel and citric acid significantly (p<0.05) and synergistically (p<0.05) increased the total phenol and anthocyanin content of ‘Kolang-kaling’ jam in a dose-dependent manner. Meanwhile, the IC50 of the jam dose-dependently decreased with ‘jamblang’ peel and citric acid addition and was negatively correlated with total phenol content (r = -0.881) and anthocyanin levels (r = -0.683). Conclusion: The highest antioxidant activity, (1,376 ppm) was seen in jam production with 25% ‘jamblang’ peel and 0.4 g citric acid. Anthocyanin had a stronger effect on antioxidant activity than did citric acid. Although the antioxidant activity in ‘Kolang-kaling’ jam was relatively weak even with ‘jamblang’ peel and citric acid supplementation, this food still could be used as an antioxidant substance.

  Background and Objectives: This study is the first to explain in detail the process to extract gambir from Uncaria gambir. The aim of this study was to identify the process used to produce gambir. The process is called ‘mangampo,’ which yields dried gambir extracts. This unique traditional process can be useful for researchers to understand the conventional processing of natural resources with beneficial compounds. Materials and Methods: The materials used in this research were the leaves and branches of Uncaria gambir. This study conducted a survey of gambir processing methods in Pesisir Selatan and Lima Puluh Kota, the central regions of gambir production in West Sumatra. Results: The results of this study showed that the procedure of ‘mangampo’ consists of harvesting the leaves and branches, steaming until condensed water appears on the leaves and branches, pressing the steamed leaves and branches, collecting the extract, thickening the extract (until a paste forms), forming the gambir paste and drying the paste. Conclusion: In both regions (Pesisir Selatan and Lima Puluh Kota), the same principle of extracting gambir is used and ‘mangampo’ is a unique traditional method to produce gambir.
