The objective of this research was to investigate the antioxidant properties Salvadora persica leaf extracts using various in vitro assays and compare them with total phenolic content. Petroleum ether, benzene, chloroform, methanol, aqueous were assessed for their ability scavenge free radicals such as DPPH, superoxide, hydroxyl along metal chelating capacity reducing power. Estimation content ...

Using conventional methods it is impossible to extract RNA as uncomplexed intact molecules from the leaves of grapevines (Vitis vinifera L.) and from a number of woody perennial species that contain high levels of reactive phenolic compounds. A procedure involving the use of high concentrations of the chaotropic agent sodium perchlorate prevents the binding of phenolic compounds to RNA during e...

Restrictions on the use of synthetic antioxidant such as butylated  hydroxyanisole  (BHA) and butylated  hydroxytoluene (BHT) are being imposed  because of  their carcinogecity. In this investigation  optimization  of phenolic extraction  process  frome  methanolic (80%)  extract (v/v) of  elaegnus  angustifolia  through  Response  Surface Methodology  by fulin cio- calteu is  performrd  for op...

In this work, the ultrasound-assisted extraction (UAE) (operating conditions of sonication amplitude, pulse-cycle, and time) was investigated to obtain an extract rich in biologically active compounds from Annona muricata leaves. addition, content bioactive by optimal UAE (UAE extract) compared with extracts prepared decoction infusion. Moreover, Artemia salina toxicity evaluated all extracts. ...

introduction this study was intended to evaluate the nutritional value, phenolic compounds and digestibility coefficients of barberry leaves. berberis vulgaris is one of the major crops in the province. the province has more than 70 percent and 95 percent of the total area under cultivation of barberry. waste and foliage of barberry harvest traditionally used to feed livestock tannin concentrat...

Psidium guajava L. is widely used like food and in folk medicine all around the world. Many studies have demonstrated that guava leaves have anti-hyperglycemic and anti-hyperlipidemic activities, among others, and that these activities belong mainly to phenolic compounds, although it is known that phenolic composition in guava tree varies throughout seasonal changes. Andalusia is one of the reg...

OBJECTIVE The study was conducted to investigate the antibacterial and anthelmintic activities and to determine total phenolic contents of methanolic extract of Piper betel leaves. MATERIALS AND METHODS The extract was subjected to assay for antibacterial activity using both gram positive and gram negative bacterial strains through disc diffusion method; anthelmintic activity with the determi...

Lime or Citrus aurantifolia L., is a small citrus fruit that belongs to the family Rutaceae. The fruit and leaves of C. aurantifolia have been used traditionally for weight loss, skin care, relief from constipation and treatment of scurvy, etc. The purpose of this study was to determine the flavonoid, total phenolic content and investigation of anti-oxidant potential of Citrus aurantifolia leav...
