Aqueous leaf extract of L. speciosa (banaba) effectively decreased the blood glucose in streptozotocin-induced diabetic mice after 15th day of banaba exposure. Further, banaba leaf extract have the potential to inhibit lipid peroxidation and effectively intercept/neutralize reactive oxygen species such as super oxide, H2O2 and NO based free radicals. The aqueous banaba leaf extract (150 mg/kg b...
Effect of different pH levels, temperature, light intensity and media were tested against the growth of A. alternata under in vitro conditions. The results of experiment indicated that the growth of A. alternata was maximum in pH range of 6.006.50 and temperature range of 25 30°C. The exposure of the fungus to alternate cycles of 12 hour light and 12 hour darkness resulted in the maximum myceli...
Leaf extract of guava (Psidium guajava Linn.) has been reported to promote wound healing in traditional medicine but there is paucity of information in literature regarding similar activity of fruit extract. Therefore, the present study was planned to investigate the influence of leaf and fruit extract of Psidium guajava Linn. on re-sutured incision, excision, and dead space wounds in male Wist...
there are considerable efforts to identify naturally occurring substances as new drugs in cancer therapy. many components of medicinal plants have been identified that possess substantial anticancerous properties. this prompted us to investigate the effect of scrophularia striata (an iranian species belonging to the scrophulariace family) extract on the growth of astrocyte cancer cell line (132...
brazilian peppertree (schinus terebinthifolius) leaf extract was applied against two strains of the crown gall disease agent (agrobacterium tumefaciens); strains c58 and ar125. in vitro, we used the agar well diffusion method and the extract was tested in different solvents selected according to their polarity indices, at different concentrations and different incubation temperatures. in vivo, ...
BACKGROUND Vernonia amygdalina, commonly called bitter-leaf, is widely consumed in many parts of Africa, and Nigeria, in particular. The leaf extract has been reported to have antimicrobial, anti-plasmodial, anti-helminthic, as well as prebiotic properties, but its immuno-modulatory effects have not been well-studied, neither have the prebiotics been identified. This study evaluated the immuno-...
Ginkgo biloba leaf is the leaf of Ginkgo biloba L. in the genus Ginkgo of family Ginkgoaceae. It has the actions of benefiting heart, astringing lung, resolving dampness and stopping diarrhea, which can be used in the treatment of chest distress and pain, palpitation, phlegm panting and cough, diarrhea, dysentery, leucorrhea and other symptoms. Main active constituents of Ginkgo biloba leaves a...
Introduction: Our previous studies showed that hydroalcoholic extract of leaf of Vitis vinifera relaxes the phenylephrine-induced contraction in rat thoracic aorta. This effect was dependent on endothelial integrity and NO-cGMP system. The vasorelaxant effect of extract was much lesser on KCl-induced contraction. We, therefore, postulated that K+ channels are involved. The main aim of the pr...
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...
