Composition, antioxidant capacities and cell inhibition properties of curcuminfree turmeric (Curcuma longa L.) oils from different sources were evaluated by chromatographic method, two different in vitro antioxidative activity assays (DPPH* free radical scavenging assay and reducing power assay) and two different cancer cell lines (Caco-2 and MCF-7). Turmeric oil A (TOA) contains zingiberene, t...

background & aim: chorisia is an important bombacaceous plant that is traditionally used for a variety of ailments. due to its richness in several bioactive phytocompounds, some chorisia species showed a wide range of important biological effects. accordingly, the present work was undertaken to comparatively evaluate the antioxidant potential and effects on adipogenesis of chorisia chodatii...

BACKGROUND Arctium lappa, known as burdock, is widely used in popular medicine for hypertension, gout, hepatitis and other inflammatory disorders. Pharmacological studies indicated that burdock roots have hepatoprotective, anti-inflammatory, free radical scavenging and antiproliferative activities. The aim of this study was to evaluate total phenolic content, radical scavenging activity by DPPH...

The preparation process of protein enzymolysis technology for the three-spot seahorse (Hippocampus trimaculatus Leach) degreased bone meal was developed. Two enzymes with better enzymolysis effect were selected from the five proteases, and the optimization condition of the Alkaline Protease is temperature - 54.7°C, pH - 9, duration of 6 h, the acquired rate of polypeptides was 11.77%; and that ...

Bee-collected pollen ("bee pollen") is promoted as a health food with a wide range of nutritional and therapeutic properties. The objective of the current study is to evaluate the contribution made through the free radical scavenging capability of bee-collected floval pollens by their flavonoid/phenolics constituents, and to determine whether this capability is affected by aging. The free radic...

Objective. Oxidative stress leads to numerous physiological disorders including infectious diseases, inflammation, and cancer. The present study was carried out to investigate antioxidant, antibacterial, and cytotoxic activity of methanol crude extract of leaves and fruits of the Ficus racemosa (LCME and FCME, resp.) and to analyse its major bioactive polyphenols by HPLC-DAD. Methods. Antioxida...

this study was designed to examine the in vitro antioxidant activities and total phenolic contents of the methanolic extracts from male inflorescence of salix aegyptiaca l. grown in iran. the methanolic extract (me) and its three fractions including water (wf), butanol (bf) and chloroform (cf) were prepared and then their antioxidant activities, as well as total phenolic contents, were evaluate...

the methanol extracts of leaves of bauhinia acuminata (mesf) and their different fractions obtained from modified kupchan partitioning method i.e. methanol, pet ether, carbon tetrachloride, chloroform, and aqueous soluble fractions were subjected to biological screening such as total phenolic content and antioxidant activity screening.the amount of total phenolic content differed in different e...

Antioxidant activity of methanolic extract of Abutilon indicum leaves was investigated for its free radical scavenging activity by determining the nitric oxide and superoxide radical scavenging activity. Maximum scavenging of nitric oxide and superoxide radical found were 28.74 % and 49. 62 % respectively at 250 μg/ml concentration.
