Nutrients, bioactive compounds and antioxidant activities of walnut male inflorescences at four flowering stages were analyzed in this study. The results showed that the male inflorescences were rich in carbohydrate, protein and mineral contents, and had antioxidant activities due to high contents of phenolic and flavonoid compounds. The nutritional compositions were varied at four stages. In t...

Article history: Received on: 03/04/2016 Revised on: 05/05/2016 Accepted on: 30/06/2016 Available online: 26/09/2016 Marine algae are potential sources of biologically active compounds with antiviral, antimicrobial and anticancer activities. Two species of marine algae, Padina boryana Thivy and Enteromorpha sp were collected from the Red Sea. Both species were extracted with ethanol, acetone, a...

Commercial buckwheat flours were investigated for their antioxidant activities, free, and bound phenolic compositions using spectrophotometer, LC–ESI-IT-MS, and LC–ESI-Q-TOF-MS. Farinetta flour contained the highest free and bound phenolic contents, followed by Supreme, whole buckwheat, and Fancy flour, respectively. The 50% ethanol extraction achieved significantly higher free phenolic content...

The antioxidant activity, contents of total phenolics and flavonoids were quantified in the methanolic extracts of four Ulva species(U.clathrata,U.linza,U.flexuosa and U.intestinalis) grown at different parts of northern coasts of the Persian Gulf in south of Iran.The seaweeds were collected from Dayyer,Taheri and Northern Ouli coasts in April 2011. Methanolic extracts of the seaweeds were asse...

Increased consumption of vegetables or plant food has been associated with decreased risk of developing major chronic diseases, such as cancers, diabetes, cardiovascular diseases, and age-related functional decline. Ramie leaves are rich in phenolics and flavonoids, which have been suggested for human health benefits. Phenolic contents, flavonoid contents, phenolic compounds, and anti-cancer pr...

Many plants are used ethnomedicinally for the treatment of disease and restoration health. One these medicinal is Tithonia diversifolia . This study aims to determine phenolic flavonoid contents antioxidant activity using DPPH method from leaves T. Phenolic identification was carried out with FeCl 3 reagent; blackish green color formed indicates presence compounds. Identification a reagent betw...

The present study was designed to evaluate and compare the phenolic (total phenols and flavonoid) contents and antioxidant activity of aqueous extract of Momordica foetida (AEMF) and ethanolic extract of Momordica foetida (EEMF) extract of Momordica foetida leaves; a popular medicinal plant used for traditional medicine preparations. The antioxidant activity of both extracts was assessed using ...

Tecoma stans (Bignoniaceae) is used in the treatment of diabetes, stomach pains, rheumatism, diuretic, vermifuge and tonic in traditional medicine. The present study has been design to evaluate antinociceptive and anti-inflammatory activities of alcohol and aqueous extracts of Tecoma stans leaves and to determine total phenolic and flavonoid contents. Both extracts shows dose dependent activity...

Rosa canina L. is a member of Rosaceae family, which is well-known for its high phenolic contents. These compounds are known to possess antioxidant and antiradical effects. In order to compare the antioxidant and antiradical activity of wild Rosa phenolic extracts, two wild Rosa species (Rosa canina L. and Rosa pimpinellifolia L.) were selected from Takab, Oshnavieh and Qasemloo Valley of Urmia...

Extraction methods are very important processes for separation of bioactive compounds of medicinal plants before analyses. Phenolic and flavonoid compounds include a broad variety of structures and functionalities that are required for the production of foods and food additives and there are different methods for the their extraction. In this study, total phenolic and flavonoid contents of leaf...
