OBJECTIVE Oxidative stress plays a key role in the pathophysiology of brain ischemia and neurodegenerative disorders. Previous studies indicated that Viola tricolor and Viola odorata are rich sources of antioxidants. This study aimed to determine whether these plants protect neurons against serum/glucose deprivation (SGD)-induced cell death in an in vitro model of ischemia and neurodegeneration...

Climate change is recognized as an important threat to global biodiversity because it increases the risk of extinction of many species on the planet. Mexico is a megadiverse country and native tree species such as red cedar (Cedrela odorata) can be used to maintain forests while helping mitigate climate change, because it is considered a fast growing pioneer species with great economic potentia...

Pratylenchus vulnus is involved in a desease of Rosa noisettiana 'Manetti' rose rootstock characterized by darkening of roots, death of feeder roots, and stunting of entire plants. The disease is more severe when plants are grown in silt loam soil than when they are grown in sandy loam soil. The nematodes reproduce best in silt loam soil at 20 C. Meloidogyne hapla did not affect the growh of Ma...

The forest tree Spanish cedar (Cedrela odorata L.) is well-known for its high-value timber; however, this species is attacked by the shoot borer (Hypsipyla grandella) during its early years of development, resulting in branched stems and making the plants useless for high-quality wood production. The generation of resistant varieties expressing entomotoxic proteins may be an alternative to pest...

The evolution of competitive ability of invasive plant species is generally studied in the context of adaptive responses to novel biotic environments (enemy release) in introduced ranges. However, invasive plants may also respond to novel abiotic environments. Here we studied differences in competitive ability between Chromolaena odorata plants of populations from nonnative versus native ranges...

Chromolaena odorata L (Asteraceae) is a bad invasive plant, found in the humid tropics and sub-tropics worldwide. It is used against dysentery, diarrhea, malaria, wound healing, headache and toothache in traditional medicine. In the present study, we investigated the antibacterial activities of different leaves extracts of Chromolaena odorata L. (cyclohexane, dichloromethane, ethyl acetate and ...

Six groups of adult Sprague-Dawley rats were orally administered with a variety of treatments to elucidate their cytoprotective effects. Absolute ethanol combined with HCl was used to induce gastric lesions in rats. Aqueous and ethanol extracts of Chromolaena odorata, a famous folk herb for treating skin wounds were evaluated to determine their protective effect on gastric mucosa. In this study...

Annonaceae (custard-apple family) canang odorant (French); chiráng, irang (Palau); derangerang, derangirang (Nauru); ilahnglahng, ilanlang (Kosrae); ilang-ilang, alang-ilang (Guam, CNMI); ilangilang, lengileng, alangilang, pur-n-wai, pwurenwai, seir en wai (Pohnpei); ilanilan (Marshall Islands); lanalana (Hawai‘i); makosoi, mokohoi, makasui, mokosoi (Fiji); mohokoi (Tonga); moso‘oi (Samoa); mot...

Objective: Oxidative stress is associated with the pathogenesis of brain ischemia and other neurodegenerative disorders. Previous researches have shown the antioxidant activity of Viola odorata L. In this project, we studied neuro-protective and reactive oxygen species (ROS) scavenging activities of methanol  (MeOH) extract and other fractions isolated from <e...

Background: Chromolaena odorata (C. odorata) is a medicinal plant with hypoglycemic effect known in traditional medicine. The present study investigated the in vitro antioxidant and in vivo anti-hyperglycemic effect of the methanol root extract of C. odorata in rats. Methods: Phytochemical compositions were evaluated, using standard procedures while the antioxidant activities were examined, us...
