ABSTRACT

Within this study, phytochemical, fatty acid and proximal composition of six Indonesian brown rice cultivars (Inpari 42, Inpari 43, Situ Bagendit, IPB3 S, Inpari 17, and Inpara 3) were reported. The range of moisture, ash, crude fat, crude protein, and total carbohydrates content of six varieties of brown rice were 11–12%, 1.3–1.4%, 2–3%, 7–11%, and 84–89%, respectively. Fatty acid composition of brown rices was dominated by unsaturated fatty acids. The phenolic contents and IC₅₀ of all cultivars varied from 47 to 70 mg GAE/100 g and 28–47 mg/mL, respectively. Inpari 17 had the highest phenolic content as well as antioxidant activity, whereas IPB 3 S variety exhibited the lowest in both γ-oryzanol content of brown rices ranged from 37 to 55 mg/100 g. The highest content of γ-oryzanol was observed in Inpara 3. In conclusion, six varieties of Indonesian brow rice might be considered as the potent sources of bioactive compounds and antioxidant, especially in Inpari 17 variety.

摘要

在这项研究中，报告了六个印度尼西亚糙米品种（Inpari 42，Inpari 43，Situ Bagendit，IPB3 S，Inpari 17和Inpara 3）的植物化学，脂肪酸和近端成分。六个糙米品种的水分，灰分，粗脂肪，粗蛋白和总碳水化合物含量范围分别为11–12％，1.3–1.4％，2–3％，7-11％和84–89％，分别。糙米的脂肪酸组成以不饱和脂肪酸为主。酚含量和IC ₅₀所有品种的GAE分别为47至70 mg / 100 g和28–47 mg / mL。Inpari 17具有最高的酚含量和抗氧化活性，而IPB 3 S品种的糙米γ-谷维素含量最低，范围从37至55 mg / 100 g。在第3节中观察到了最高的γ-谷维素含量。总而言之，印度尼西亚眉毛稻的六个品种可能被认为是生物活性化合物和抗氧化剂的有效来源，尤其是在Inpari 17品种中。
