“…The lack of differences among RP and SβC treatments for βCMO1 and βCO2 expression in the small intestine in the present study indicate that β‐carotene may have been primarily absorbed intact and may be a reason why Condron et al . () observed that carotenoids dramatically increased in the plasma of feedlot steers fed increasing concentrations of SβC.…”

“…Expression of ADH1 in the small intestine tended ( P = 0.06) to decrease with increasing SβC in the diet, indicating that the increased retinoic acid found in the plasma and LM of cattle fed increasing concentrations of SβC (Condron et al . ) may have inhibited ADH1 expression through a negative feedback mechanism. Vitamin A‐related genes are tightly regulated and feedback inhibition by retinoic acid has been demonstrated for many other vitamin A‐related genes (Elizondo et al .…”

“…Cattle were allowed ad libitum access to feed and water and were fed a basal diet containing (dry matter basis) 20% dried distillers grains with solubles (DDGS), 20% corn silage, 57.3% corn, 1.7% vitamin/mineral supplement and 1% of a corn/VA supplement (Condron et al . ). Experimental diets were formulated to meet or exceed NRC () requirements for protein, energy, vitamins and minerals.…”

“…We demonstrated in a companion paper (Condron et al . ) that feeding increasing concentrations of β‐carotene (1, 5 and 10× the requirement) increased the amount of circulating β‐carotene, retinyl palmitate and retinoic acid, and can meet the vitamin A requirement for beef cattle. However, β‐carotene increased yellowness of fat and did not affect intramuscular fat content.…”

To examine the effects of dietary β-carotene (βC) or retinyl palmitate (RP) on fatty acid (FA) profile and mRNA expression, samples were collected from 24 Angus-cross calves that were allotted to four treatments consisting of RP supplemented at 2200 IU/kg, and synthetic β-carotene (SβC) supplemented at one, five or 10 times RP. Longissimus muscle (LM) cis-9, trans-11 conjugated linoleic acid was greater in RP compared to SβC1X (P = 0.04). The polyunsaturated:saturated FA increased linearly (P = 0.04) in the LM as dietary SβC increased. Expression of βC oxygenase 2 (βCO2), an enzyme that cleaves β-carotene, was greater in the LM for SβC1X compared to RP and decreased linearly as SβC increased (P ≤ 0.02). Peroxisome proliferator activated receptor γ (PPARγ) expression in the LM increased in SβC1X compared to RP (P = 0.03); however, PPARγ and retinoic acid X receptor α (RXRα) expression decreased linearly (P = 0.02) in the LM with increasing SβC. Retinoic acid receptor α (RARα) expression tended (P = 0.10) to decrease linearly in the LM with increased SβC. In conclusion, SβC supplementation increased mRNA expression of some lipogenic genes in the LM, but increasing dietary SβC inhibited their expression and tended to increase polyunsaturated FA.

Antioxidants from fruits, vegetables and beverages play an important role in human health, for example preventing cancer and cardiovascular diseases, and lowering the incidence of different diseases. In this paper the main classes of antioxidants are presented: vitamins ( vitamin C and vitamin E); carotenoids; polyphenols (flavonoids, flavonols, flavones, flavanones, anthocyanins, isoflavones); phenolic acids; tannins; stilbenes; and lignans. Recently, many analytical methodologies involving diverse instrumental techniques have been developed for the extraction, separation, identification and quantification of these compounds. The main methods of antioxidant extraction are: extraction with solvents, extraction with supercritical fluids, microware-assisted extraction, subcritical water extraction, ultrasonics, pulsed electric fields, high hydrostatic pressure, high voltage electrical discharges and enzyme-assisted extraction. Antioxidants have been quantified by different researchers using one or more of these methods: in vivo, in vitro, electrochemical, chemiluminescent, electron spin resonance, chromatography, capillary electrophoresis, nuclear magnetic resonance, near infrared spectroscopy and mass spectrometry methods.
