“…This result suggested that most compound of the horse mussel extract consisted of polar compounds and more water-soluble substances, which was proven by the lower yield in hexane (22.6 %, w/w) and EtOAc fraction (6.5 %, w/w). The highest yield of water fraction in this partition was in line with other studies; green seaweed C. fulvescens, C. monoiligera, and U. pertusa (Cho et al 2010), and medicinal herb Smilax excelsa L. leaf extract (Ozsoy et al 2008), where the water fraction resulted in the highest extraction yield. These results indicated that each solvent fraction could be different in both the composition and the ratio of their constituents.…”

The Korean horse mussel extract was purified and fractionated by a bioassay-guided purification step. The final fraction contained seven steroid and one polycyclic aromatic compounds, in which cholest-7-en-3-ol, (3b,5a)-(58.7 %) was a main component followed by ergosta-7,22dien-3-ol (3b,5a,22E) (13.0 %). This extract exhibited strong anti-inflammatory activity determined solely through the nitric oxide inhibition assay in a dose-dependant manner with the IC 50 value of 9.6 lg/mL and no cytotoxic effect on the macrophages. Moreover, it also exhibited strong cytotoxicity with the IC 50 values of 21.4, 36.4, and 37.1 lg/mL against AGS, DLD-1, and HeLa cells, respectively. These results indicated that the horse mussel extract might be a functional ingredient in the prevention of inflammation and human cancers.

“…This value was almost consistent with the value obtained for GA. Because, the 1.4 mg/ml of the GA was scavenged the hydroxyl radical in the ratio of 68%. Very similar results have been reported in the literature for S. excelsa L. leaf extracts [25].…”

“…The results showed that the highest content of total phenolic compouns found in extract obtained with water. A similar conclusion was also reached in a study on Smilax excelsa L. leaf extracts [25]. But the examples such that of an investigation on Cynara cardunculus extracts [23] indicate this can not be so always, are also available in the literature.…”

SummaryIntroductıon: Instead of synthetic antioxidants, using of natural products with antioxidant activity is demanded.Objectıve: The aim of this study is to evaluate the antioxidant activity and total phenolic and flavonoid contents of theTrachystemon orientalis(borage) obtained from Ordu.Methods: The water and ethanol extracts of the borage plant were investigated by using severalin vitroantioxidant activity tests such as total antioxidant capacity, O2•−,•OH, DPPH and ABTS radicals scavenging activities, hydrogen peroxide scavenging activity, FRAP, Fe2+chelating and reducing power assays in order to make effective comparisons.Results: Water extract of theT. orientalishad the more phenolic (90 mg GA/g extract) and flavonoid (56.88 mg CT/g extract) contents than ethanol extract. Furthermore, both of the extracts showed strong antioxidant and radical scavenging activities determined by differentin vitromodels. The highest total antioxidant capacity as ascorbic acid equivalents of 244.50 mg/g extract was also calculated for water extract. Generally, a relationship between total phenolic content and antioxidant activity was established. It is also an important finding for an edible food source that the phenolic and flavonoid content and antioxidative activities for water extract was higher than the ethanol extract.Conclusıon:T. orientaliscould be used as a food ingredient instead of synthetic antioxidants and all results will contribute to the recent increase in investigations on using natural products in many areas such as food, pharmacy, alternative medicine and natural therapy.

Abstract-Miracle fruit has unique protein which can make sour flavors to sweet, and the bright red skin might be a natural pigment. After the harvest of miracle fruit, removal of fruit skin, fruit meat, the fruit seeds become natural side product using for biofertilizer. Recently, a growing research reports focus on the investigation of fruit seeds for screening potential antioxidants, such as steroids, phenols, and flavonoids as well. In this research, we verity miracle fruit seed is great multi-antioxidant source by different extraction solution. 3μg (GAE)/mg total phenolic and 3.1μg (RUE)/mg flavonoid content was measured when the miracle fruit was extracted by acetic acid buffer with 20mM at pH6.0 and pure ethanol. The antioxidation ability of DPPH and ABTS free radical scavenging was over 70%, chelating effect of ferrous ions reached 80%.Index Terms-Miracle fruit, fruit seed, total phenolics, antioxidant activity.
