Objective: The aim of the present work was to assess the total phenolic content (TPC), total flavonoid content (TFC), and total alkaloid content (TAC) of crude hydro-methanolic seed extract of Abrus precatorius L. which is one of the beautiful seed bearing plant belonging to family Fabaceae and used extensively in many Ayurvedic preparations with significant therapeutic significance. Methods: T...

In this work we investigated the in vivo protective effects of Baccharis dracunculifolia leaves extract (BdE) against carbon tetrachloride (CCl4)- and acetaminophen (APAP)-induced hepatotoxicity. Total phenolic content, total flavonoid content, antioxidant DPPH radical scavenging activity, and HPLC analysis were performed. Our results showed that pretreatment with BdE significantly reduced the ...

Mentha pulegium which is locally know as Al-Medina mint, is used in herbal teas or as additives in commercial spice mixtures for many foods to offer aroma and flavor. The objectives of this study were to examine the antioxidant activity and the total phenol and flavonoids contents of Mentha pulegium methanol extract. The In vitro antioxidant activity of Mentha pulegium methanol extract was eval...

In this study, caffeic acid (CA) and its three derivatives including 3-caffeoylquinic acid (3-CQA, neochlorogenic acid), 4-caffeoylquinic acid (4-CQA, cryptochlorogenic acid), and 5-caffeoylquinic acid (5-CQA, chlorogenic acid) were identified in Bupleurum chinense aerial parts using reverse-phase high-performance liquid chromatography (RP-HPLC) with photodiode array (PDA) detector, reference c...

OBJECTIVE To investigate the antioxidant activities as well as phytochemical constituents of Antidesma thwaitesianum Müll. Arg. leaf extracts. METHODS The leaves of A. thwaitesianum were extracted using three different methods: blending with distilled water, maceration with ethanol and decoction. The chemical antioxidant activity of the plant leaf extracts was evaluated using 2,2-diphenyl-1-p...

The mineral contents of Centaura leave and seeds were determined by Inductively Coupled Plasma-Atomic Emission Spectroscopy (ICP-AES). Macro element concentrations (P, K, Ca, Mg and S) of samples were found at high levels. K was established at high level in both leave and seed samples of Centaurea. While K contents of leaves changes between 7254.10 mg/kg (Centaurea lycaonica) and 26396.36 m...

Raphanus sativus L., a small-sized red radish, is an important root vegetable crop found worldwide and is commonly used in salads. The objective of this study was to measure the total phenolic and flavonoid content as well as to evaluate the antioxidant activity of the ethanol extract of Raphanus sativus L. cv. Cherry Belle and Raphanus sativus L. cv. Valentine. The total phenolic content and t...

Pomegranate (Punica granatum L.), Lythraceae, is mainly grown in Mediterranean region. It is one of the major cultivated productions of Iran, which have been used in folk medicine for many centuries. It has been proved that pomegranate has a high antioxidant activity and is effective in the prevention of atherosclerosis. This study compares the antioxidant activity, total phenolic and flavonoid...

Hairy root systems are formed by transforming plant tissues with the “natural genetic engineer” Agrobacterium rhizogenes. In most plants such as Cichorium intybus L., hairy root cultures have proven to be an efficient system for secondary metabolites production. The effect of Zinc (ZnSO4), a heavy metal, was investigated at different concentrations (0, 1, 5 and 10 mM) on some secondary metaboli...

In Indonesia, Caesalpinia pulcherrima (L) Swartz is widely grown as an ornamental, whereas it is used as a medicinal herb in Mexico as an alternative treatment for dental and oral infections. At present, only fruit and root parts of the plant are used. The aim of this study was is evaluate the anti-microbial activity of ethanol extract of fruit, leaves, flowers and stems against microbes that c...
