Chemical manipulation of tomato growth and associated biochemical implications on flavonoid, lycopene and mineral contents
The consumption of tomato (Solanum lycopersicon) has been linked with reduced risk of chronic degenerative diseases. Therefore, this study was carried out to investigate the biochemical implications of bioregulator application on flavonoids, lycopene, calcium, magnesium, potassium, sodium, phosphorus and iron contents of tomato. Seeds of the tomato, genotype JM 94/47 were subjected to pre –germination...

Essential oils analysis of the rhizomes of Alpinia conchigera Griff. and leaves of Alpinia malaccensis (Burm. f.) Roscoe from Bangladesh
The essential oils obtained by hydrodistillation of the rhizomes of Alpinia conchigera Griff. and leaves of Alpinia malaccensis (Burm. f.) Roscoe were analysed by gas chromatography mass spectrometry (GC-MS). 74 compounds were identified in A. conchigera rhizome oil among them, 40 had not been detected previously. The major chemical class was terpenoids, with eucalyptol (25.85%),...

Antibacterial potential of crude leaf extracts of Eucalyptus camaldulensis against some pathogenic bacteria
The antibacterial activity of the crude leaf extracts of Eucalyptus camaldulensis were determined using the agar well diffusion method against clinical isolates of Escherichia coli, Staphylococcus aureus, Salmonella typhi, Proteus mirabilis andKlebsiella pneumoniae. At an extract concentration of 50 mg/ml, the growths of all the pathogenic bacteria were arrested, though to...
