Cytotoxic and Genotoxic Effects of Aqueous Extracts of Rosmarinus officinalis L., Lavandula stoechas L. and Tilia cordata Mill. on in vitro Human Peripheral Blood Lymphocytes
Abstract
The aim of this study was to investigation of in
vitro cytotoxic and genotoxic effects of infusion and decoction aqueous
extracts obtained from Rosmarinus officinalis, Lavandula stoechas
L. and Tilia cordata Mill. on human peripheral blood lymphocytes.
For this purpose, lymphocytes taken from 3
females, were treated with aqueous extracts of R. officinalis (1.5 and 3
mg/ml), L. stoechas (0,4 and 1,2
mg/ml) and T. cordata (1 mg/ml and 3 mg/ml) for 48 hours. PBS was used
as negative control and Mitomycin C (MMC) (0,25 μg/ml) was used as positive
control in experiments. Cytotoxic effect of extracts on lymphocytes was
determined by calculating mitotic index. Also, chromosome aberrations
micronucleus formations were determined.
All extracts considerably decreased the
cell division in lymphocytes depending on the increased concentration in
comparison with control groups (p<0,01). Also cells in metaphase decreased.
Thus, no chromosomal aberration was observed in lymphocytes. However, extract
treatments induced the formation of micronucleus in lymphocytes when compared
to control groups (p<0,01). 3 mg/ml decoction extracts of L. stoechas and
T. cordata showed the highest cytotoxic effect on lymphocytes, and the
highest genotoxic effect appeared after 48 h treatment with 1.2 mg/ml decoction
extract of L. stoechas.
