Total antioxidant activity on serum was determined by DPPH method. The ascorbic acid equivalent antioxidant capacity (AEAC) of rice bran greater than tomato juice is 28.74 mg/100g and 1.87 mg/100g respectively. The total antioxidant activity on serum was decreasing after tomato juice intervention (p>0.05) but the decreasing of it was significantly shown after rice bran intervention (p<0.05)</span><span style="font-size: 10pt;">.</span></p>

The Effect of Rice Bran Cereals on Total Cholesterol, Malondialdehyde (MDA) Levels and Histopathology Description of Aortic Organ on Mice Model of Hypercholesterolemia

“…It suitable with Wulandari et al [16] that rice bran extracts of red rice reduced free radicals by using DPPH reagent. The antioxidant activity of rice bran and tomato juice was also examined by Damayanti et al [14], and showed that antioxidant activity in the rice bran was higher than tomato juice, which were 83.89% and 60.74%, respectively.…”

“…The results of this research showed that antioxidant activity of rice bran cereals had IC50 value of 75.18 μL/mL, this results revealed that the antioxidants contained in the sample (rice bran cereal) appertain to the strong category. IC50 values range of 151-200 mg/mL are included in the low category, 101-150 mg/mL is medium, 50-100 mg/mL is categorized as strong and below from 50 mg/mL specifically indicates that the sample compound contains very powerful antioxidants [14,15]. It suitable with Wulandari et al [16] that rice bran extracts of red rice reduced free radicals by using DPPH reagent.…”

Development of Cream Soup Made From Combination of Black Soybean (Glycine soja L. merrit) and Red Rice (Oryza nivara) as an Alternative Functional Food for Menopausal Women

“…Total anthocyanin content was analyzed using AOAC Official Method 2005.2 with HPLC, total isoflavones were analyzed by HPLC method, and total microbial analysis was performed by using total plate count method at 30 0 C for 72 hours (SNI 2008). Total antioxidant activity was assessed by DPPH scavenging activity method and expressed in ascorbic acid equivalent antioxidant capacity (AEAC) (Kubo et al 2002;Damayanthi et al 2010). The nutrient contribution to the RDA of menopausal women (50-60 years) included energy, protein, fat, carbohydrates, and dietary fiber.…”

Analisis Indeks Glikemik Dan Komposisi Gizi Keripik Simulasi Substitusi Tepung Bekatul Dengan Tepung Labu Kuning

“…Tepung labu kuning dapat digunakan pada produk roti, sup, saus, mi instan dan sebagai suplemen alami untuk makanan (Noor Aziah et al, 2011). Bekatul adalah produk samping hasil pengolahan beras yang kaya nutrisi seperti serat pangan, mineral, vitamin B komplek, vitamin E, asam lemak esensial, asam amino, dan antioksidan (Astawan, 2009;Damayanthi et al, 2010, dan Pasha et al, 2002.…”
