  • The objective of this study was to compare antioxidant effects of different extracts of Salicornia bigelovii seed. DPPH radical scavenging activity, chelating activity of ferrous, superoxide anion radical-scavenging activity, hydroxyl radical scavenging activity, and contents of total polyphenol and flavonoid were measured for different extracts. Ethanol extract (10 mg/mL) was found to have the maximum DPPH radical scavenging and superoxide anion radical scavenging activities (65.26 and 62.36%, respectively). However, hot water extract (10 mg/mL) showed the highest hydroxyl radical scavenging and chelating activities (51.50 and 53.24%, respectively). Total phenolics and flavonoid contents in the ethanol extract were 522.8 and $480.35{\mu}g/mg$, respectively. They were 401.51 and $352.60{\mu}g/mg$, respectively, in the hot water extract. These results indicate that ethanol and hot water extracts of S. bigelovii seed have good potential to be used as a new source of antioxidants for functional foods, cosmetics, and pharmaceuticals.

  • Natural dye extracted from Salicornia bigelovii was applied to silk fabrics by dip dyeing process. The dyeing properties and the functionalities of the silk fabrics were determined. Factors affecting the dyeing properties such as dyestuff concentration, temperature, time and pH were studied. The colorimetric parameters $L^*$, $a^*$, $b^*$, and H, V/C values were measured to select the optimal mordanting conditions. The color-fastnesses of the dyed and mordanted fabrics were estimated for practical use; in addition, the antibacterial property, ultraviolet protection properties were evaluated. The dyeabilities of silk increased depending on the increasing dye concentration, dyeing time, and dyeing temperature. And optimum dyeing results were achieved when dyeing with 300% (o.w.f.) of dye concentration at $90^{\circ}C$ for 100 minutes and at pH 3. The dyed silk fabrics without mordants produced yellow (Y) color and showed yellow (Y) or green yellow (GY) colors depending on the mordants type. The light fastness of dyed and Al mordanted silk fabrics were found to be excellent, and the drycleaning and rubbing fastness were good. The dyed silk fabrics showed no antibacterial property, but Al and Cu mordanted silk fabrics showed 99.9% reduction rate. The ultraviolet protection properties of the dyed silk fabric was improved. And the ultraviolet protection properties of mordanted samples showed very good ultraviolet protection properties.

  • The hypolipidemic and antioxidant effects of dietary supplementation with polysaccharide isolated from Salicornia bigelovii seed (SBS) were evaluated in hypercholesterolemic rats. Following administration of SBS polysaccharide at 200 mg/kg BW/day (HPS group), total cholesterol (TC), and low density lipoprotein cholesterol (LDLC) levels were 32.45% and 58.09% lower than those in negative controls (NC) group, respectively. However, in the case of high density lipoprotein cholesterol (HDLC), it was 36.37% higher than that of NC group. The arteriosclerosis and cardiac risk indices were 64.23% and 50.53% lower than in the NC group. However, the HTR (HDLC/TC) value was higher 2.05-fold than that of the NC group. Hydroxy-3-methylglutaryl CoA reductase activity in HPS group was 55.1% lower than that of the NC group. Activities of alanine transferase, aspartate aminotransferase, and alkaline phosphatase in HPS group were 29.71%, 26.49%, and 32.24%, lower than that of the NC group. SOD, CAT, and GSH-Px activities in HPS group were 31.05%, 49.29%, and 54.62% higher than that of the NC group. These results indicate that SBS polysaccharide has both hypolipidemic and antioxidant effects and shows potential for ameliorating hypercholesterolemia.

  • This study investigates the effect of Salicornia bigelovii extract on the activities of antioxidant, anti-wrinkle and whitening. Among amino acids, the glutamic acid concentration was the highest with an order of proline > alanine > $\gamma$-amino-n-butyric acid > arginine. The total polyphenol concentration and antioxidant activity were an order of ethyl acetate extract > n-butanol extract > hexane extract > hot water extract > ethanol extract. Especially, when ethylacetate was used as extractant, the total polyphenol concentration and antioxidant activity were 31.6 mg/mL and 82.6%, respectively. The inhibition activity of tyrosinase was increased with the increase concentration of ethylacetate extract. Especially, when the extract concentration was increased from 20 to 100 mg/mL, it was raised from 15.2 to 98.2%. In the case of inhibition activities of elastase, and collagenase, they were also increased with the increase concentration of ethylacetate extract. When the extract concentrations were increased from 20 to 100 ug/mL, they were enhanced from 2.9 to 32.5% and from 3.8 to 29.7%, respectively. The results show that the ethyl acetate extract of Salicornia bigelovii can be applied as sources for functional cosmetics and pharmaceuticals.

  • A metabolism trial was conducted with 28 Najdi rams allocated into seven dietary groups to evaluate the effect of dietary inclusion of Salicornia bigelovii Torr biomass on nutrient digestibility, rumina I fluid metabolites and nitrogen and mineral balances. Either the stems (ST) or spikes (SP) of this seawater-irrigated halophyte were incorporated into complete diets at rates of 0, 10, 20 and 30% levels, replacing equal amounts of rhodesgrass hay in a ground mixed control diet. Digestibility of DM, OM, EE, NFE and fecal and urinary nitrogen were not affected by increased level of ST in the diet. As level of ST increased from 0 to 20% in the diets, CP digestibility and nitrogen retention approached their maximum (p<0.01), whereas CF digestibility reached its minimum (p<0.01). On the other hand, except for EE, digestion of all nutrients and nitrogen retention were linearly depressed (p<0.01) as SP increased in the diets from 10 to 30% level. Concentration of ammonia-N, total VFA and pH values in the rumen fluid were lower (p<0.01) with the ST- or SP-fed diets than with the control diet. Increasing level of ST or SP in the diet was associated with an increase (p<0.01) in the proportion of acetate and a decline (p<0.01) in molar percentage of propionate in the ruminal fluid. Sodium absorption increased (p<0.01) with increased ST and SP in the diets up to the 10 and 20% level, respectively, followed by constant absorption values up to the 30% level. When the level of ST in the diet gradually increased to 30%, a concomitant increased (p<0:01) in Ca and P absorption were obvious; whereas, increased level of SP in the diets from 0 to 30% resulted in noticeable (p<0.01) depression in Ca and P apparent absorption.
