“…Both decreasing lipid peroxidation and improving antioxidative status are beneficial to optimal meat quality. Moreover, latest reports have noted that ramie leaf contains polyphenols and flavonoids which are considered to be the major contributors to the antioxidant capacity (Lee, Kim, & Lee, ). In view of the forgoing, we believe that the ramie meal likely influences antioxidant status of the pigs because of the observation that activities of T‐SOD.…”

“…In addition, diets that contain antioxidants promoted activities of antioxidant enzymes and delayed lipid oxidation status of meat (Descalzo & Sancho, ). Antioxidant defence systems are composed of enzymes (such as SOD and GPX), non‐enzymatic water and lipid soluble compounds (such as vitamin C and polyphenols which are rich in ramie) (Lee et al, ). Together, enzymatic and non‐enzymatic defence systems operate to counteract the action of pro‐oxidants in meat.…”

This study was conducted to evaluate the effects of ramie (Boehmeria nivea, previously known as a fibre crop and also called "China grass") included in diets on growth performance, antioxidative capacity and muscular fatty acid profile of finishing pigs.A total of 180 Xiangcun Black pigs (initial body weight =70.71 ± 1.21 kg) were randomly allotted to 1 of 5 dietary treatments with six pens of six pigs per pen. The pigs were provided a basal diet or a diet contained 3%, 6%, 9% or 12% of ramie powder during a 50-day experiment period. The results showed that the inclusion of ramie increased (quadratic, p < 0.05) the average daily gain (ADG) and gain:feed ratio (G:F) with the highest value of ADG and G:F in 3% ramie group, but ramie content in the diet up to 9% reduced the growth performance of the pigs compared with that of 3% ramie group. The activity of serum total superoxide dismutase (SOD) was increased (linear, p < 0.05) by ramie, while content of malondialdehyde was decreased (linear, p < 0.05). As increasing the dietary ramie level, the mRNA expression level of SOD1 was increased quadratically (p < 0.05) in muscle tissues. Moreover, the addition of ramie linearly increased (p < 0.05) polyunsaturated fatty acids content, whereas it linearly reduced (p < 0.05) the lipid indices of atherogenicity (AI) and thrombogenicity (TI) in muscle tissues, and lower values of AI and TI reflect a "healthier" fat composition. The results indicated that ramie in a diet not more than 9% may improve antioxidative capacity with no detrimental impact on growth performance of Chinese native finishing pigs; meanwhile, it could beneficially change the pork fatty acid pattern which has a positive impact on consumer's health.

“…The role of plant phenolics in the prevention against chronic diseases such as cardiovascular, diabetes and neurodegenerative diseases has been suggested in many studies [4,5,6]. Recent studies explored diversified health benefits of ramie leaves, such as antioxidant, anticancer, anti-inflammatory, anti-obesity, antibacterial activities, and hypoglycemic and hypolipidemic effects [7,8,9,10,11,12], which might be attributed to the bioactive phenolic compounds. Except for leaves, roots of ramie are also listed in the Chinese Pharmacopoeia, due to medicinal function in heat-clearing and detoxicating, hemostasis, and preventing miscarriage [13].…”

Comparative Study of Phenolic Profiles, Antioxidant and Antiproliferative Activities in Different Vegetative Parts of Ramie (Boehmeria nivea L.)

Ramie (Boehmeria nivea L.) is usually cultivated as a fiber crop, but it is also well known for its potential use in animal feeding with viable commercial applications. In this study, the phenolics profile as well as cellular antioxidant and antiproliferative activities were investigated in free and bound fractions of six different vegetative parts from Boehmeria nivea L. The highest total phenolic content was observed in bud (4585 ± 320 mg GAE/100 g DW), whereas root and petiole had the lowest total phenolic contents, 442.8 ± 9.8 and 630.9 ± 27.0 mg GAE/100 g DW, respectively. Likewise, phloem had the most abundant total flavonoids (2755 ± 184 mg CE/100 g DW), whereas the lowest flavonoid contents was found in root and petiole, 636.9 ± 44.2 and 797.4 ± 87.6 mg CE/100 g DW, respectively. Xylem and bud depicted remarkable antioxidant and antiproliferative activities, which could be explained by their diverse phenolic composition, especially chlorogenic acid and epicatechin. The Boehmeria nivea L. plant might be a valuable resource for high value-added phenolic compounds used in food and non-food industries.

“…A high antioxidative capacity is known to be beneficial with respect to meat quality and shelf life ( Ma et al., 2010 ; Lu et al., 2014 ; Zhang et al., 2015 ), and in this regard, ramie is rich in antioxidants, including polyphenols and flavonoids ( Kim, 2010 ). In rats, the serum lipid profile ( Lee et al., 2014 ) and lipid metabolism ( Lee et al., 2011 ) can be improved by providing these animals with ramie leaf extract or dietary ramie leaf inclusion. In finishing pigs, carcass traits and muscle chemical composition can also be improved by the inclusion of up to 9% ramie leaf powder in the diet ( Li et al., 2018a ).…”

Ramie ( Boehmeria nivea ) is noted for the production of a large biomass that has a high protein content and is rich in antioxidants. It may thus serve as a high-quality forage material to replace alfalfa and improve the meat quality of farmed animals. In this study, we evaluated the carcass characteristics and meat quality of goats when 0, 35%, 75%, and 100% of dietary alfalfa was replaced with ramie. Crude protein content (linear, P < 0.0001) and key muscle color values at 24 h after slaughter decreased with increasing ramie levels. The content of most individual amino acids, non-essential amino acids (NEAA), total amino acids (TAA), branched chain amino acids (BCAA), functional amino acids (FAA), and flavor amino acids (DAA) decreased ( P < 0.05) with increasing dietary ramie. The diet in which 35% of alfalfa was replaced with ramie yielded meat with the highest amino acid content, whereas the fatty acid profile was unaffected by the inclusion of ramie. These results indicate that ramie could be used as a potential dietary forage resource for goats, and that substituting 35% of alfalfa with ramie, which is equivalent to 126 g/kg DM content, would be optimal in terms of goat meat quality.
