“…Poplars are members of the family Salicaceae, contain various naturally-occurring aromatic compounds such as salicylic acid, salicylic alcohol, aromatic ketones, terpenoids, fatty and organic acids, benzyl alcohol, beta-phenylethanol, salicin, and other compounds (Pearl and Darling 1970;Browning 1967;Sentsov et al 1997;Steele and Ronald 1973). The researchers also demonstrated that most of these compounds showed antibacterial activity such as salicylic acid (Bartzatt et al 2007), benzoic acid (Park et al 2001), aromatic ketones, fatty and organic acids (Herald and Davidson 1983;Lattman et al 2005). The poplar origin of Turkish propolis is well documented (Popova et al 2005).…”

The antibacterial activity of propolis has been widely investigated. Since reports dealing with antimicrobial activity of the origin of propolis are not available, this study was carried out aiming to analyse the in vitro antimicrobial activity of the methanol extracts of poplar type propolis and Populus (Populus nigra, P. alba, P. tremuloides) buds as its sources against standard strains of a panel of microorganisms by determining the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC). The concentrations of the ''poplar'' phenolics were relatively high (4.5%) and some compounds typical for P. nigra such as pinobanksin and 4,3 acetyloxycaffeate were found in the propolis sample by GC-MS. The poplar type propolis and Populus bud exudates were found to inhibit most clinically important microorganisms in a wide spectrum including pathogenic yeasts but not Gram-negative bacteria.

“…Among these are antimicrobial agents such as 3,3,4-trimethyl-4-p-tolyl, naphthalelone derivitives (Shan et al, 1997), nicotinic acid (Bartzatt et al, 2007), 5-phenoxymethyl-1,3,4-thiadiazol-2-amine (Siddiquia et al, 2009), acetate 3-cyclohexen-1-ol (Lu et al, 2010), boron (methanamine)tris(trifluromethyl) (Borokhov and Schubert, 2007), 2-methyl,1-penten-3-yne (Beuerle and Schwab, 1997) and 4-ethylformanilide (Zhang and Huang, 2005). There are several new compounds, which have so far not been reported from any propolis samples.…”

Capsicum annuum is one of the main vegetable crops for the local market and exportation in Egypt. In this concern, pepper mild mottle virus (PMMoV) infection caused a significant decrease in Capsicum sp. yield, leading to large economic losses. An isolate of PMMoV was got from naturally infected pepper plants, exhibiting different patterns of mottling, leaf distortion, yellowing, and stunting of leaves. The virus was identified. The molecular detection of PMMoV was done using RT-PCR with specific primers designed for coat protein genes. An RT-PCR product (~ 474) bp of the coat protein gene of (PMMoV) was cloned. The target of the investigation was the effect of spring and autumn ethanol extracts of Populus nigra leaves on C. annuum seedling growth and infected C. annuum with (PMMoV) under greenhouse conditions. The experimental data showed that treated spring leaf extract of P. nigra enhanced infected C. annuum seedling growth parameters and fruit quality compared to uninfected seedlings. P. nigra spring leaf extract containing some allo-chemicals had a negative effect on uninfected seedlings. P. nigra autumn leaf extract significantly improved the growth and fruit quality of infected C. annuum seedlings compared to the control.
