The aim was to study the antioxidant properties of four wine polyphenols (flavonoids catechin, epicatechin, and quercetin, and hydroxystilbene resveratrol). All three flavonoids exerted significant and dose-dependent scavenging effects against peroxyl radical and nitric oxide in chemical systems. The scavenging effect of resveratrol was significantly lower. All polyphenols decreased production ...
Diabetes Mellitus (DM) is a major metabolic disorder causing morbidity and mortality worldwide. The prominent adverse effects of allopathic drugs are the principal reason for an escalating number people seeking alternative complementary-based therapies that may have less or no effects. poly-herbal formulation Vilva Kudineer Choornam (VKC) combination Siddha medicinal plants treatment diabetes. ...
Introduction: Curcuma amada Roxb. usually referred as ambahaldi is an exceptionally aromatic rhizomatic herb which contains number of phyto constituents responsible for several pharmacological activities. Present study attempt to explore antioxidant and analgesic activity ethanolic extract C. amada. Objectives: The goal this work was assess the Methods: For in-vitro study, DPPH (2, 2-Diphenyl-1...
bioactive food components (such as phenolic compounds, carotenoids, anthocyanins, tochopherols, ascorbic acid, flavonoids, minerals, enzymes and pectin) are active ingredients in food or dietary supplements, which proven to have an important role in health, and are safe for human consumption. these compounds exert their antioxidant effects by different mechanisms such as single electron transfe...
Withania somnifera of the family Solanaceae has been considered as an important herb in the traditional Ayurvedic and in the indigenous medical system in Bangladesh for its use in the prevention of different central nervous system (CNS) disorders, especially in the conditions of stress and neurodegenerative diseases. Five different extracts of Withania somnifera root were scrutinized to unfold ...
The interplay between nitric oxide and superoxide to form peroxynitrite is a major biological process that competes in a remarkably subtle fashion with superoxide dismutase in vivo. The complex interactions between superoxide, nitric oxide reveals some extraordinary features about the difficulties of effectively scavenging of superoxide in a biological system. The discovery of dominant mutation...
The genus Galium (Rubiaceae), comprised of approximately 1300 species and used for the treatment of a variety of pathological conditions in folk medicine of many cultures. In this study, antioxidant activities of aerial parts of G. verum were investigated employing various in vitro assay systems, i.e. DPPH and nitric oxide radical scavenging, reducing power and H2O2 scavenging. IC50 for DPPH ra...
BACKGROUND Recent investigations have shown that the antioxidant properties of plants could be correlated with oxidative stress defense and different human diseases. In this respect flavonoids and other polyphenolic compounds have gained the greatest attention. The plant Cytisus scoparius contains the main constituent of flavone and flavonals. The present study was undertaken to evaluate the in...
Essential oils from plants have been proven safe as natural antioxidants, and few are already marketed as digestive enhancers as well as in prevention of several degenerative diseases. This study evaluated the antioxidant capacity of seed and shell essential oils of Abrus precatorius (L), a herb used for ethno-medicinal practices in Nigeria. The essential oils were obtained by hydro-distillatio...
Plants are excellent source of natural antioxidants which have beneficial effect on health. The present study was designed to assess the antioxidant and reactive oxygen species (ROS) scavenging activities of 70% methanolic extract of Clerodendrum viscosum. The extracts were examined for the scavenging activity of hydroxyl radical, nitric oxide, singlet oxygen, hypochlorous acid, superoxide, per...
