Objectives: This study aims to detect the active compounds found in ethanolic crude extract of Curcuma longa
rhizome and evaluate the cytotoxic effect of ethanolic extract on two malignant cell lines; Human laryngeal
Carcinoma (HEP-2) cell line, murine mammary adenocarcinoma (AMN-3) cell line and one transformed cell line
of Rat Emberyogenic Fibroblast (REF-3).
Material and methodology:
Administrative Arrangement: This study was conducted in Iraqi Centre for Cancer and Medical Genetic
Research (ICCMGR), Baghdad, Iraq to period (1 / 1 / 2011 to 1 / 1 / 2012), periods of exposure of cell lines
Different concentrations were prepared from ethanolic extract starting from (1 to 10000) μg/ml to were
measured at (24 , 48 , and 72)hrs in a microtitration plate under complete sterile conditions.
Results:Chemical detection of extract appeared that the ethanolic extract contain flavonoid, saponin, phenols ,
resins , volatile oils , tannins , terpins and steroids while glycosids, alkaloids and cumarines gave negative results
appeared the ethanolic extract of curcuma longa showed inhibition effect at 48 hr. period for all concentration on
cancer cell lines. And amount the inhibition percentage of (AMN-3) cell line (88.3%) for treatment in
concentration( 6μg/ml) after (24hr). from exposure time, and inhibition percentage begin in lower concentration
on (Hep-2) cancer cell line and gave inhibition percentage (77.1%)after treatment in (2000 μg/ml) after (48hr).
from exposure time and appeared the ethanolic extract on REF transformed cell line and gave higher inhibition
percentage( 93%) after treatment in (100μg/ml) from exposure time.
Conclusion: The ethanolic crude extract of Curcuma longa Which contain flavenoid, saponin, phenols, resins,
Volatile Oils, tannins, terpins and steroids while alkaloids, glycosids, and cumarines gave negative results, In the
in vitro study,Theethanolic crude extract of C. longa has a potent cytotoxic activity against REF transformed cell
line, AMN-3 and Hep-2 cell lines in a concentration and time dependent manners (in vitro), The cell lines REF
and AMN-3 were the most sensitive to the inhibitory effects of ethanolic extract of C. longa rhizomes,The cell
line Hep-2 showed less response at low concentration while the extract had cytotoxic effect at highest
concentration after exposure 48 hr.
Recommendations:Using further different cancer cell lines as well as normal cell lines to study the cytotoxicity
of Curcuma longa extract such as oral , stomach and colon cell lines. Using the comet test technique to detect
the effects of plants extracts on DNA, use different solvent to extract ofCurcuma longa for example methanol. |
