Cytotoxicity Test of Ethyl Acetate Fraction and Ethanol Fraction of Papaya Leaf Extract (Carica Papaya. L) Against Hep-2 Laryngeal Cancer Cells

Abstract

Papaya leaves are used as medicine for fever, malaria, increased appetite, constipation, and anti-cancer. In the previous study using the Brine Shrimp Lethality Test (BSLT), an ethanol extract of papaya leaf had an LC50 value of 23.73 mg/mL. This suggests that papaya leaves are a compound, that uses a 70% ethanol extract of papaya leaves and has cytotoxic potential. Research objectives: This research aimed to determine the cytotoxic effect of the ethanol and ethyl acetate fractions of a 70 % ethanol extract of papaya leaf against Hep-2 cells. Performed in vitro by the direct calculation method (viable cell count), so its LC50 is known. The ethanol and ethyl acetate fraction of papaya leaf extract as a test solution was made in 5 concentrations, with concentrations of 20.93; 16.26; 12.64; 9.82, and 7.63 µg/ml. Result: The results obtained the LC50 ethanol fraction of 11.2616 μg/ml and the ethyl acetate fraction of LC50 12.4 of 882 μg/ml. Conclusion: Based on this, it can be concluded that the fraction of ethanol and ethyl acetate extracts of papaya (Carica papaya L.) have cytotoxic properties against Hep-2 cells in a range that goes very, very toxic, i.e., 5–50 µg/ml, and have the potential to be developed as an anticancer drug.
