Brown rice: a missing nutrient-rich health food

Momilactones and Phenolics in Brown Rice: Enrichment, Optimized Extraction, and Potential for Antioxidant and Anti-Diabetic Activities

“…A simple ordinary least-squares (OLS) regression was run using the following equation to examine the impacts of different factors on momilactone and phenolic contents extracted from BR and GBR: Y = a 0 + βixi + ui (4) where Y = outcome, a 0 = constant, βi = impact (treatment effect), xi = treatment, and ui = error term.…”

“…Nowadays, consumers are increasingly drawn to pigmented rice varieties for their richness in bioactive constituents, such as antioxidants and anti-inflammatory elements [1]. Among them, brown rice (BR) not only serves as a nutritional powerhouse but also boasts a remarkable array of bioactive compounds that contribute to human health benefits [2][3][4]. BR contains a high level of phenolics and flavonoids, showcasing potential properties that combat oxidative stress and inflammation in the body [5,6].…”

“…On the other hand, phenolic acids, including caffeic, ρ-hydroxybenzoic, ρ-coumaric, ferulic, salicylic, and cinnamic acids are more abundant in rice, and are known for their bioactive attributes, comprising antioxidant, anti-inflammatory, and anticancer properties [15]. It is noteworthy that these phenolic compounds are primarily concentrated in the bran layer [4], making them generally more abundant in BR than in white rice [16,17]. Furthermore, the quantities of these phenolic compounds in GBR can be twice as high as those found in BR [4].…”

Furthermore, the quantities of these phenolic compounds in GBR can be twice as high as those found in BR [4]. In addition, momilactones A (MA) and B (MB) have been acknowledged as valuable diterpene lactones from rice (Oryza lineage) [18], which exhibit various medicinal properties, including antioxidant [11], anticancer [19][20][21], anti-diabetic [10,12], anti-obesity [12], and anti-skin aging [11] potentials.…”

Recent trends of potential medicinal uses of rice bran with its composition and bibliographic analysis

“…Similarly, Japanese fermented brown rice with Aspergillus oryzae (FBRA‐1) has been found to show carcinogenic preprotection activity in the urinary bladder, stomach, lungs, colon, and liver of rodents. FBRA‐1 have also shown chemoprotective effects on N‐nitrosobis‐(2‐oxopropyl) amine caused pancreatic tumorogenesis in male hamster via regulating the tumor cell proliferation rate (Kuno et al, 2015; X. Wu et al, 2023). Rice bran extract and fermented rice bran have been found to mitigate inflammation.…”
