The free radical scavenging potential of the plant Alocasia indica(Linn.) was studied by using different antioxidant models of screening like scavenging of 1,1-diphenyl-2-picryl hydrazyl radical, nitric oxide radical, superoxide anion radical, hydroxyl radical, iron chelating activity, total antioxidant capacity, non-enzymatic glycosylation of haemoglobin, rapid screening for antioxidant compou...

Antioxidant activity of hydromethanolic extract of Urtica parviflora Roxb. (family Urticaceae) was investigated by different in vitro methods, namely, nitric oxide scavenging, DPPH scavenging, and reducing power assay. In the present study, plant extract exhibited dose dependent free radical scavenging and reducing activity. The antioxidant activity of the hydromethanolic extract of Urtica parv...

Lamiaceae herbs known for their culinary properties are a rich source of potentially health-beneficial antioxidant polyphenols. The objective of this investigation was to evaluate and prove the in vitro antioxidant activity of five different extracts of aerial parts of the plant Leucas aspera, belonging to the family Lamiaceae on different models namely the DPPH free radical scavenging assay, F...

In general, benzothiazole derivatives have attracted great interest due to thier pharmaceutical and biological importance. New 2-amino-6-arylbenzothiazoles were synthesized in moderate to excellent yields via Suzuki cross coupling reactions using various aryl boronic acids and aryl boronic acid pinacol esters and the antiurease and nitric oxide (NO) scavenging activity of the products were also...

Jabuticaba is an exotic fruit native to Brazil that has been arousing medicinal interest. Using chemical (HPLC-PDA, resonance mass spectra, and NMR), electroanalytical (differential pulse voltammetry, radical scavenging assay), and pharmacological (in vivo and in vitro) approaches, we have identified its bioactive compounds and hypotensive effects on hypertensive rats. The hydroalcoholic extrac...

Diabetes mellitus is a metabolic disorder which has emerged as a global public health threat in the present century. The present oral hypoglycemic agents produce undesirable side effects and oxidative stress. Thus there is a need for a safe, cost effective and complementary therapy for Diabetes mellitus. To evaluate the Nitric oxide scavenging activity and Alpha amylase inhibitory activity of P...

Lactuca indica (Compositae) is an edible wild vegetable, used as a folk medicine in anti-inflammatory, antibacterial, and other medications in Asia. This is the first scientific evaluation of the chemopreventive therapeutic properties of L. indica using five antioxidation assay systems. An extract from L. indica was found to possess significant free radical scavenging activity, effectively prot...

Bauhinia variegata L. is traditionally used in treating a variety of ailments in India. Phytochemical screening and in vitro free radical scavenging activity of aqueous and ethanolic bark extracts of Bauhinia variegata was assessed by studying its ability to scavenge DPPH, Nitric oxide, hydroxyl radical and reducing power. Phytochemical analysis revealed the presence of steroid, phenol/ tannin,...

BACKGROUND Launaea procumbens (LP) has been used as a food supplement in Pakistan. In this study methanolic crude extract (LPME) of the whole plant and its different fractions; n-hexane (LPHE); ethyl acetate (LPEE) and chloroform (LPCE) were studied for the determination of total flavonoid and phenolics contents along with multifaceted in vitro scavenging assays. RESULTS Considerable amount o...

With the aim of developing effective anti-inflammatory drugs, we have been investigating the biochemical effects of shikonin of "Shikon" roots, which is a naphthoquinone with anti-inflammatory and antioxidative properties. Shikonin scavenged reactive oxygen species like hydroxyl radical, superoxide anion (O2 (•-)) and singlet oxygen in previous studies, but its reactivity with reactive oxygen s...
