Antibacterial activity of Citrus reticulata peel extracts.
Citrus peels were successively extracted with hexane, chloroform and acetone using a soxhlet extractor. The hexane and chloroform extracts were fractionated into alcohol-soluble and alcohol-insoluble fractions. These fractions were tested against different gram positive and gram negative bacteria. The EtOH-soluble fraction was found to be most effective. Fractionation of EtOH-soluble fraction o...
متن کاملAntioxidant activities and tyrosinase inhibition effects of Phaleria macrocarpa extracts.
BACKGROUND The ethyl acetate and chloroform extracts of stems, leaves and fruits of Phaleria macrocarpa were screened for their antioxidant capacity and tyrosinase inhibition properties. MATERIAL AND METHOD The total phenolic content (TPC), 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging and ferric-ion reducing power (FRAP) were used to evaluate their antioxidant capacity. Tyrosi...
متن کاملPhenolic Content, Antioxidant Effects and Tyrosinase Inhibitory Activity of Extract of Some Stachys Species from Iran
Background: Given the importance of Stachys genus in Iran and their significant biological activity, we collected three species of this plant: St. aucheri Benth., Stachys benthamiana Boiss and St. inflata Benth. from different regions of Iran. We examined the free radical scavenging potential, total phenol content and tyrosinase inhibitory activity of their methanol, methanol 80% and dichlorome...
متن کاملAntioxidant Activities and Tyrosinase Inhibitory Effects of Different Extracts from Pleurotus ostreatus Fruiting Bodies
We evaluated the antioxidant activity and tyrosinase inhibitory effects of Pleurotus ostreatus fruiting bodies extracted with acetone, methanol, and hot water. The antioxidant activities were tested against β-carotene-linoleic acid, reducing power, 1,1-diphenyl-2-picrylhydrazyl free radical scavenging activity, and ferrous chelating ability. Furthermore, phenolic acid and flavonoid contents wer...
متن کاملAnti-hepatitis C virus effect of citrus unshiu peel and its active ingredient nobiletin.
We investigated the effects of water and ethyl acetate extracts of Citrus unshiu peel (Aurantii Nobilis pericarpium) on hepatitis C virus (HCV) absorption in MOLT-4 cells (a human lymphoblastoid leukemia cell line). By reverse transcription polymerase chain reaction (RT-PCR), we showed that both the ethyl acetate layer of Citrus unshiu peel extract and fraction 7 decreased HCV absorption in MOL...
