The antioxidant activities of crude extract of Phaulopsis fascisepala leaf were evaluated and compared with alpha-tocopherol and BHT as synthetic antioxidants and ascorbic acid as natural-based antioxidant. In vitro, we studied its antioxidative activities, radical-scavenging effects, Fe(2+)-chelating ability and reducing power. The total phenolic content was determined and expressed in gallic ...

The efficacy of different concentrations of aqueous neem leaf extract (3.12 to 50 mg/mL) on growth and citrinin production in three isolates of Penicillium citrinum was investigated under laboratory conditions. Mycotoxin production by the isolates was suppressed, depending on the concentration of the plant extract added to culture media at the time of spore inoculation. Citrinin production in f...

The antifungal potential of aqueous leaf and fruit extracts of Capsicum frutescens against four major fungal strains associated with groundnut storage was evaluated. These seed-borne fungi, namely Aspergillus flavus, A. niger, Penicillium sp. and Rhizopus sp. were isolated by standard agar plate method and identified by macroscopic and microscopic features. The minimum inhibitory concentrations...

Introduction: Olive leaf contains anti-inflammatory and COX-2 inhibitor compounds. Considering the role of the COX enzyme in seizures, this research was performed to assess the effects of this extract in treatment of seizures induced by PTZ. Methods: In this research, male Wistar rats (200±20 g) were injected intra-cerebroventricularly with 1 μl saline or olive leaf extract (125 μg, 250 μg ...

We have investigated effect of Moringa oleifera leaf and fruit extracts on markers of oxidative stress, its toxicity evaluation, and correlation with antioxidant properties using in vitro and in vitro assays. The aqueous extract of leaf was able to increase the GSH and reduce MDA level in a concentration-dependent manner. The ethanolic extract of fruit showed highest phenolic content, strong re...

The phytochemical and pharmacological studies of leaf, bark and fruit extracts of Samadera indica were carried out on aqueous and methanolic extracts, obtained by soxhlet technique. The qualitative tests showed the presence of carbohydrates, proteins, phenolics, alkaloids, saponins, flavonoids, tannins and resins, whereas quantitative estimations of carbohydrate, protein, phenolics and tannins ...

Malaria is one of the most important infectious diseases in the world. The choice for the treatment is highly limited due to drug resistance. Hence, finding the new compounds to treat malaria is urgently needed. The present study was attempted to evaluate the antimalarial activity of the Annona muricata aqueous leaf extract in Plasmodium berghei infected mice. Aqueous leaf extract of A. muricat...

Water hyacinth (Eichhornia crassipes) is one of the most productive plants, but is also a troublesome weed in the world. In order to protect the public water system from chemical herbicides pollution, biological method has been suggested to control the growth and the reproduction of this weed. Lantana (Lantana camara L.) is an important weed of the family Verbenaceae and its leaf extract is hig...

The main objective of this study is to evaluate the gastroprotective activity of the Phyllanthus niruri leaf extract against ethanol-induced gastric mucosal injury in rats. Six groups of Wistar rats were pretreated, respectively, with distilled water; omeprazole 20 mg/kg; and 250, 500, 750 and 1000 mg/kg P. niruri leaf extract 30 min before oral administration of absolute ethanol to generate ga...
