Seabuckthorn (Hippophae rhamnoides) seeds aqueous extract was screened for antioxidant and antibacterial activities. The antioxidant activities (reducing power, DPPH and liposome model system) showed a good antioxidant activity. The extract was also found to possess antibacterial activity with a MIC
The present study was carried out to investigate the antioxidant, cytoprotective and antibacterial effects of aqueous and hydroalcoholic extracts of Hippophae rhamnoides L. (Sea buckthorn) (SBT) leaves by using various in vitro systems and analysis of marker compounds by reverse phase-high
Background: Sea buckthorn is a good and possible source of a wide range of bioactive compounds with a positive effect on the human body, especially polyphenols and carotenoids.
Methods:
Objective of the present study was to investigate the antibacterial activity of Sea buckthorn (Hippophae rhamnoides L.) berries and leaves against methicillin resistant Staphylococcus aureus (MRSA) by using the standard disc diffusion method. Chloroform, n-hexane and aqueous extract of the plant
Ethnopharmacological relevance: Hippophae rhamnoides L. (family- Elaeagnaceae, common name- Sea buckthorn) is a flowering shrub native to cold temperate regions of Eurasia. Berries, seeds, and leaves of the plant are widely used as a folk
The purpose of this study was to conduct phytochemical analysis of sea buckthorn pulp oil and to evaluate the antimicrobial, anti-biofilm and antioxidant activities of its mouthwash form.METHODS AND RESULTS
Fatty acid composition of the sea buckthorn
Essential oils from the seed, pulp, and leaf of sea buckthorn were obtained with hydrodistillation, and their phytochemical composition was analyzed through gas chromatography-mass spectrometry. Furthermore, the antibacterial activity of the oils was tested on five food-borne bacteria by
Phenolic rich fraction (PRF) from Seabuckthorn leaves was prepared by sequential fractionation. Total phenolic content of PRF estimated as gallic acid equivalent was found to be 319.33±7.02 mg/g of PRF. Its major constituents gallic acid, rutin, quercetin-3-galactoside, quercetin-3-glucoside,
Hippophae rhamnoides L. is an important source of natural antioxidant and antimicrobial agents. Phytochemical compounds, antioxidant and antibacterial properties of berries, and leaf extracts from four Romanian sea buckthorn cultivars were investigated. Large differences in the content of
BACKGROUND
Staphylococcus epidermidis is one of the most frequent causes of biofilm-associated infections on indwelling medical devices. With the emergence of methicillin-resistant S. epidermidis (MRSE), there is an urgent need to discover novel active agents against a range of Gram-positive
Hippophae rhamnoides (sea buckthorn) offers many health benefits. It has significant cardioprotective activity and exerts many positive healing effects on the cardiovascular system, including inhibiting blood platelet activation (especially platelet aggregation), lowering cholesterol concentration
Staphylococcus aureus, like other gram-positive pathogens, has evolved a large repertoire of virulence factors as a powerful weapon to subvert the host immune system, among which alpha-hemolysin (Hla), a secreted pore-forming cytotoxin, plays a preeminent role. We observed a concentration-dependent
Hippophae rhamnoides, is a high altitude plant, possesses immunomodulatory, anti-oxidant, anti-bacterial and adaptogenic activity and is widely used in treatment of various diseases. The present study was designed to ascertain the safety of aqueous extract of H. rhamnoides fruit when administered by
Infection by Helicobacter pylori has been ascertained to be an important etiologic impetus leading usually to chronic active gastritis and gastric ulcer with growing incidences worldwide. Utilizing as the test pathogen a standard and five clinic strains of Helicobacter pylori, the antibacterial
