The Natural Pigments in Pigmented Rice Bran and Their Relation to Human Health: A Literature Review

Carotenoids and polyphenols are the natural pigments which are distributed to the pigmented rice bran. These pigments can prevent chronic disorders related to oxidative stress and antioxidant properties. This article focuses on carotenoids and polyphenols as ones among the natural pigments. Carotenoids and polyphenols exert an antioxidant property and anti-inflammatory agents; enhance immune responses and prevent Age-related Macular Degeneration (AMD). In combination with protein and dietary fiber, the bioavailability of carotenoids decreases in gastrointestinal tract. The inefficient absorption of anthocyanins in the small intestine resulted from unstability of the physiochemical pH and the degradation of anthocyanins in the small intestine. These have led to low bioavailability of anthocyanins

Chemical Constituents From the Aerial Part of <i>Tiliacora triandra</i> (Colebr.) Diels and Their α-Glucosidase and α-Amylase Inhibitory Activity

Two new fatty acid derivatives identified as 5,7-dihydroxy-6-oxoheptadecanoic acid (1) and ethyl-5,7-dihydroxy-6-oxooctadecanoate (2) together with four known compounds, ethyl linolenate (3), ethyl linoleate (4), ethyl pheophorbide A (5), and pheophorbide A (6), were isolated from the aerial parts of Tiliacora triandra. All the compounds were isolated from T. triandra for the first time. The structures of the compounds were elucidated using high-resolution electrospray ionization mass spectrometry, 1-dimensional and 2-dimensional nuclear magnetic resonance spectroscopy, and comparison with literature data. All the isolated compounds were evaluated for their in vitro inhibitory activity against α-glucosidase and α-amylase. Compounds 1-6 exhibited α-glucosidase inhibitory activity with half-maximal inhibitory concentration values (IC50) values in the range of 11.58-424.06 μM, while only compound 1 displayed inhibitory activity against α-amylase at an IC50 value of 26.27 μM. </jats:p
