Oxidative stress is an imbalance between the rate of production and clearance of oxidant, which ultimately causes the various pathologies. Antioxidants are any substances, including endogenous and exogenous antioxidant which can inhibit the oxidation reaction. Currently, antioxidant supplementation derived from natural source, especially medicinal plants is more interested. Thunbergia laurifolia, a Thai traditional...

Chemical and structural characterization of Candelilla (Euphorbia antisyphilitica Zucc.)
This work describes the chemical and micro-structural characterization of candelilla (Euphorbia antisyphilitica Zucc) plant which produces a natural edible wax. Chemical composition analysis included total fat, protein, crude fiber, dry material, moisture, ashes, total of reducing sugars, hydrolysable and condensed polyphenols contents. Micro-structural characterization was made using Environmental scanning...

Antioxidant potential and secondary metabolites in Ocimum sanctum L. at various habitats
In this study, the secondary metabolites and antioxidant property of holy basil (Ocimum sanctum Linn.) Plant at various habitats was compared with those of respective callus cultures induced from each explants in in-vitro. The callus cultures were successfully initiated on Murashige and Skoog (MS) medium supplemented with 2,4-dichlorophenoxy acetic acid (2,4-D) (1 mg/L) combined with different concentrations...

Antihyperglycemic and antioxidant activities of Rhododendron schlippenbachii maxim. bark and its various fractions
In this research, we evaluated the antidiabetic and antioxidant potential of 80% aqueous methanolic extract of the bark of Rhododendron schlippenbachii Maxim. along with its various fractions (n-hexane, dichloromethane, ethyl ethanoate, n-butyl alcohol and distilled water). The antihyperglycemic activity of all the fractions was investigated in vitro by α-glucosidase inhibition...

Evaluation of antifungal effect of organic extracts of Algerian Citrullus colocynthis seeds against four strains of Aspergillus isolate from wheat stored
Anti-mycotic activity of the methanolic and aqueous extracts from Algerian Colocynth(Citrullus colocynthis L. Schrad) seed parts were screened in vitro against four important plant pathogenic fungi, namely, Aspergillus flavus, Aspergillus ochraceus, Aspergillus fumigatus and Aspergillus niger, using micro-dilution technique in the broth medium after their phytochemical analysis. The...

Cholinesterase inhibitory activity of Morinda lucida
Morinda lucida was found common in recipes given by Traditional Medical Practitioners in South Western Nigeria either as memory enhancer or anti-ageing. The oven dried leaves were extracted with 80% methanol and screened for both acetyl (AChE) and buteryl (BuChE) cholinesterase inhibitory activities. Fractionation of the crude extracts, followed by ethyl acetate bulk extraction, precipitation studies, phytochemical...
