The leaves of Eucalyptus have multiple biological activities such as antimicrobial, antiseptic, antioxidant, and antifungal. A Soxhlet extraction, SLE, HD were used to obtain extracts from the six species, E. globulus, oblicua, pavaflora, camaldulensis, viminalis, nitens, study their antioxidant capacity. Solvents acetone, dichloromethane, ethanol, hexane, methanol, water how polarity influence...

Quorum sensing (QS) is a key regulator of virulence and biofilm formation in Pseudomonas aeruginosa and other medically relevant bacteria. Aqueous extracts of six plants, Conocarpus erectus, Chamaesyce hypericifolia, Callistemon viminalis, Bucida buceras, Tetrazygia bicolor, and Quercus virginiana, were examined in this study for their effects on P. aeruginosa virulence factors and the QS syste...

methanol extracts of callistemon viminalis (sol. ex gaertner) g.don ex loudon fruits, bark and leaves were tested for molluscicidal activity. snails were collected and kept in dechlorinated water under standard condition. ten adults b. alexandrina, of the same size, were introduced in plastic acquaria for each experiment. the powdered organs extracted with methanol and the dried extracts were k...

The identity of a population eucalypts from Howes Swamp Creek in the eastern part Wollemi National Park New South Wales has remained unresolved for over 35 years. Despite several workers inspecting both site and trees growing there this period, little consensus been achieved on its taxonomic status. Various suggestions have made that entity was new species with affinities to Eucalyptus dalrympl...

ba ckground: mosquitoes are well known as vectors of several disease causing pathogens. the extensive use of synthetic insecticides in the mosquito control strategies resulted to the development of pesticide resistance and fos- tered environmental deterioration. hence in recent years plants become alternative source of mosquito control agents. the present study assessed the larvicidal and ovipo...
