Abstract
Radical scavenging activity of extracts obtained from 16 plants harvested in South Hungary was assessed and compared to the activity of ascorbic acid standard. During extraction, a novel technique involving an ethanolic treatment at ambient temperature was used for advanced active component release. Although the procedure is time consuming, it serves as an efficient and harmless route to extract valuable antioxidant compounds from their natural sources. The as-prepared extracts consist of two phases (except Allium sativum), a clear solution and a thick suspension containing solid plant parts that separates in about 2 h. The samples were analysed by the antioxidant assay based on the scavenging of 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radicals. For most of the species, the solid phase retained considerable amount of available antioxidant agents, while the solution parts showed significant radical scavenging activity. The main exceptions were Nigella sativa, Hippophae rhamnoides and Linum usitatissimum, where the solid parts were less active. Overall, the extracts possessed remarkable antioxidant activity that were compared to published literature data and were found to be superior.

Abstract
Inflammatory response caused by early weaning stress in piglets is associated with various diseases. The Hippophae rhamnoides polysaccharide (HRP) exhibits anti-inflammatory activity and immunomodulatory properties. The mechanisms for the protective effects of HRP on barrier function, inflammatory damage and apoptosis in intestinal porcine epithelial cells (IPEC-J2) induced by the lipopolysaccharide (LPS) are unknown. In this study, we first demonstrated the cytotoxicity of HRP-induced IPEC-J2 cells by reducing cell viability. IPEC-J2 cells were treated with 0-800 μg/mL doses of HRP, and 0-600 μg/mL doses were used in further experiments. Upon exposure to LPS, the viability of IPEC-J2 cells, ROS production, immunoglobulin levels (immunoglobulin M (IgM), immunoglobulin A (IgA) and immunoglobulin G (IgG)) and tight junction protein level (zonula occludens-1 (ZO-1), occluding, claudin-1) decreased. Inflammatory factors (interleukin-1beta (IL-1β), interleukin-6 (IL-6), interleukin-8 (IL-8) and tumor necrosis factor-alpha (TNF-α)) and apoptosis (Bcl-2, Bax, caspase-3, caspase-8 and caspase-9) were increased. Cell morphology and internal structure were damaged in the LPS treatment. Pre-treating cells with HRP (0-600 μg/mL) reduced inflammatory factors levels, apoptosis rate, increased immunoglobulins, tight junction protein levels and relieved cell surface morphology damage. Pre-treatment with HRP also reduced the levels of the Toll-like receptor 4 (TLR4) and Myeloid differentiation factor 88 (MyD88) and inhibited the phosphorylated NF-κB factor-kappa B (NF-κB) in cells induced by LPS. These results show that pre-treatment with HRP protected against LPS-induced IPEC-J2 cell damage through its anti-inflammatory activity.

Abstract
Polysaccharides are a main active substance in Panax ginseng; however, microwave-assisted extraction used to prepare P. ginseng polysaccharides (MPPG) has rarely been reported, and knowledge of the bactericidal activity of P. ginseng polysaccharides remains low. Thus, this study was designed to investigate the extraction of P. ginseng polysaccharides by using two methods-hot water extraction and microwave-assisted extraction-and compare their chemical composition and structure. In addition, their antibacterial and antioxidant activities were also determined. The data implied that P. ginseng polysaccharides extracted by microwave-assisted extraction possessed a higher extraction yield than hot water extraction (WPPG) under optimized conditions, and the actual yields were 41.6% ± 0.09% and 28.5% ± 1.62%, respectively. Moreover, the preliminary characterization of polysaccharides was identified after purification. The WPPG with the molecular weight (Mw) of 2.07 × 105 Da was composed of Man, Rib, Rha, GalA, Glu, Gal, and Arab, and the typical characteristics of polysaccharides were determined by IR spectra. Compared with WPPG, MPPG had a higher Mw, uronic acid content, and Glu content. More importantly, the antioxidant activity of MPPG was higher than WPPG, which was probably ascribed to its highly Mw and abundant uronic acid content. Besides, both of them exhibited high bactericidal activity. These results demonstrate that microwave-assisted extraction is an effective method for obtaining P. ginseng polysaccharides, and MPPG could be applied as an antioxidant and antibacterial agent.
