Skin diseases can get natural therapies from medicinal plant-based products. In this study, a topical cream was formulated ethanol extract of Acacia sieberiana, beeswax and Vitellaria paradoxa (shea) butter. GC-MS characterization with co-injection the revealed Stearic acid (31.43%), Palmitic (23.15%), Oleic (21.44%) Linoleic (16.20%) as major components. Seven phenolic conpounds were identifie...
Passiflora setacea D.C. is a wild species native to the Brazilian Cerrado, with agronomic and medicinal potentials. The cultivar BRS Pérola do Cerrado first registered protected of has become an alternative passion fruit market due its desirable characteristics for food, ornamental pharmaceutic industries. Since plant tissue culture techniques are considered important tools large-scale p...
Carissa edulis Vahl (Apocynaceae) is a plant whose leaves, roots and fruits are traditionally employed for the treatment of malaria, microbial infections, headache, cough, fever ulcer among many others. Fresh were crushed extracted with 70 % methanol 72 hours to obtain MeOH extract. Proximate analysis as well mineral composition fresh determined. Total phenolic content (TPC), total flavonoids (...
Background & Aim:Caryopteris odorata is an aromatic shrub of family verbenaceae growing in tropical to subtropical regions. Various traditional applications of this plant have been documented guiding us to investigate the pharmacological activities and to further investigate the chemical composition. Experimental: Methanolic extract of aerial par...
Free radicals are implicated for many diseases including diabetes mellitus, arthritis, cancer, ageing. etc. In the treatment of these diseases, antioxidant therapy has gained utmost importance. Alcoholic extract of Medicago sativa was studied for its in vitro antioxidant activity using different models viz. DPPH radical scavenging, ABTS radical scavenging, iron chelating activity, lipid peroxid...
N-Hydroxycinnamoylphenalkylamides (36H) exhibited both antioxidation and antityrosinase abilities. The compound was studied for its antioxidative properties, using a 1,1-diphenyl-2-picrylhydrazul- (DPPH-) scavenging test, a ferric ion-reducing antioxidant power assay (FRAP) assessment, and a metal-chelating power assay. The results showed that 36H had antioxidative capabilities in the DPPH-scav...
Previous work has indicated that respiratory activity of mitochondrial preparations prepared from lactating mammary tissue is often much lower than that of mitochondria isolated from other organs such as the liver. Initial studies in our own laboratory also found that mammary mitochondria prepared from lactating mice had much lower ATP synthesis activity than those isolated from liver tissue ob...
The low-molecular-mass fraction of the soybean nodule cytosol contains Fe capable of catalyzing free radical production through Fenton chemistry. A large portion of the pool of catalytic Fe, measured as bleomycin-detectable Fe, was characterized as complexes of Fe with phenolic compounds of three classes: phenolic acids, cinnamic acids, and flavonoids. Many of these compounds, along with other ...
OBJECTIVE The present study was an attempt to study total phenolic content and antioxidant property of the crude ethanolic extract of the roots of Azadirachta indica (A. indica). MATERIALS AND METHODS To evaluate the antioxidant properties of the crude extract, some complementary test systems, namely DPPH free radical scavenging assay, reducing power assay, and ferrous ion chelating ability a...
Phlomis crinita is a plant species of the family Lamiaceae including more than 100 perennial herbs, shrubs, and sub-shrubs native to Mediterranean, Central Asia, India. This commonly good natural source various secondary metabolites. Therefore, present study was conducted determine phenolic content antioxidant activity hydromethanolic (PC ME) aqueous extracts AQE) aerial parts P. crinita. Total...
