Abstract

Total FLAVONOIDS CONTENTS and ANTIBACTERIAL ACTIVITY of the extracts from the aerial parts of two Labiateae species, NEPETA MENTHOIDES Boiss. & Buhse and THYMUS TRAUTVETTERI Klokov & Desj.-Shost. were determined. Quantitative determination of flavonoid contents was calculated in terms of quercetin equivalent in various extracts (50% methanol, chloroform and distilled water) by AlCl3 colorimetric method. It was found that total FLAVONOIDS CONTENTS of N. menthoides extracts in different solvents were (2.308%, 0.884% and 0.710%) mg/g and (2.076%, 1.468% and 1.412%) mg/g for T. trautvetteri respectively. ANTIBACTERIAL ACTIVITY of the extracts was also determined against 6 gr (+/-) bacteria by disc diffusion method. The results showed that 50% methanol extracts of two species displayed better inhibitor activity against the tested bacteria. The bacteria Stapylococcus epidermidis, Staphylococcus saprophyticus and Staphylococcus aureus were sensitive against 50% methanol extract of N. menthoides even more than the standard antibiotics (10mg). Therefore a good correlation between total FLAVONOIDS CONTENTS and ANTIBACTERIAL ACTIVITY of the studied extracts is demonstrated.
