The present research was conducted to discover antimicrobial compounds in methanolic leaf extracts of Jatropha curcas and Andrographis paniculata and ethanolic leaf extract of Psidium guajava and the effectiveness against microbes on flower preservative solution of cut Mokara Red orchid flowers was evaluated. The leaves were analyzed using gas chromatography-mass spectrometry. A total of nine, ...

The enzyme polyphenol oxidase (PPO) catalyzes the oxidation of phenolic compounds into highly reactive quinones. Polymerization of PPO-derived quinones causes the postharvest browning of cut or bruised fruit, but the native physiological functions of PPOs in undamaged, intact plant cells are not well understood. Walnut (Juglans regia) produces a rich array of phenolic compounds and possesses a ...

the aim of this study is extraction of phenolic compounds from walnut leaves of touyserkani variety with two extraction methods (traditional method and with microwave assisted extraction (mae)) and evaluation of their antioxidant activity. total phenolic contents and antioxidant properties of aqueous, methanol (80%) and ethanol (50%) extracts in different times was determined. at the next stage...

BACKGROUND AND PURPOSE In traditional medicine, herbal products still remain the principal source of pharmaceutical agents. The present study aimed to investigate the antifungal effects of Echinophora platyloba and Rosmarinus officinalis extracts on C. albicans species. MATERIALS AND METHODS :The aqueous and ethanolic leaf extracts of E. platyloba and R. officinalis, collected from the mounta...

In this study, antifungal property of olive leaf extracts against Candida albicans PTCC-5027 was examined. Fresh olive leaf extracts were prepared using distilled water in a Soxhlet apparatus. The antifungal activity of the extract was analyzed by measuring the minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC), using the microdilution test and disc diffusion assa...

In the present study, the antibacterial and DPPH radical scavenging activities of the leaf extracts and leaf essential oil of Syzygium cumini Linn were investigated. The antibacterial potential of the leaf essential oil, petroleum ether, chloroform, ethyl acetate and methanol extracts of the leaves of Syzygium cumini Linn were studied against human pathogenic bacteria viz. Bacillus cereus, Ente...
