Bacteriostatic effect of flavonoids isolated from leaves of Psidium guajava on fish pathogens.
The antimicrobial activity against fish bacterial pathogens of flavonoids (morin, morin-3-O-lyxoside, morin-3-O-arabinoside, quercetin, and quercetin-3-O-arabinoside) isolated from the leaves of Psidium guajava was evaluated. The flavonoids were shown to have bacteriostatic effect on all of the tested bacteria.
متن کاملAntioxidant activity of Aegle marmelos and Psidium guajava leaves
Aegle marmelos, Bilwa (AM) and Psidium guajava, Guava, (PG) leaves were screened for phytochemicals by sequential extraction using a series of solvents. The antioxidant components such as β-carotene, α-Tocopherol, glutathione, ascorbic acid, total polyphenols and flavonoids were also analyzed. In addition, the leaves were extracted with methanol (ME), ethanol (EE) and water (WE) and the polyphe...
متن کاملSulfur volatiles in guava (Psidium guajava L.) leaves: possible defense mechanism.
Volatiles from crushed and intact guava leaves (Psidium guajava L.) were collected using static headspace SPME and determined using GC-PFPD, pulsed flame photometric detection, and GC-MS. Leaf volatiles from four common citrus culitvars were examined similarly to determine the potential component(s) responsible for guava's protective effect against the Asian citrus psyllid (Diaphorina citri Kuw...
متن کاملNewer insights into the mechanism of action of Psidium guajava L. leaves in infectious diarrhoea
BACKGROUND Psidium guajava L., Myrtaceae, is used widely in traditional medicine for the treatment of diarrhoea, dysentery, gastroenteritis, stomachaches, and indigestion. However, the effect of the leaf extract of P. guajava on the pathogenesis of infectious diarrhoea has not been studied. The present study evaluates the effect of a hot aqueous extract (decoction) of dried leaves of P. guajava...
متن کاملPhytochemical and Proximate Analyses of Psidium Guajava Leaves
The phytochemical and proximate analyses of Psidium guajava leaves were determined using the methods of association of official analytical chemists (A.O.A.C). The quantitative analyses showed the concentrations (mg/100g) of the phytochemical constituents as flavonoids (0.40 ± 0.02), tannins (0.55 ± 0.01), glycosides (3.76 ± 0.08), alkaloids (0.04 ± 0.00), saponins (3.01 ± 0.01), phenols (0.28 ±...
