The invention relates to a multidrug-resistant ovarian cancer cell line induced and established by triptolide and use thereof. The cell line is named SKOV3 / TPL, and the microorganism preservation number is CGMCC No. 10306. In the parental cells, the concentration of Triptolide (TPL), a monomeric extract of the traditional Chinese medicine Triptolide, was gradually increased from 10nM to 400nM, and the multidrug-resistant ovarian cancer cell line SKOV3 / TPL was established. The multidrug-resistant ovarian cancer cell line SKOV3 / TPL can stably grow, passage and recover in 400nM TPL, and its resistance index (RI) to TPL is 50.95. ‑FU, Ara‑C, GEM, VP‑16, MMC, ADM, MIT, TAX, VCR have cross-resistance. The establishment of the multidrug-resistant ovarian cancer cell line of the present invention provides a drug-resistant tumor cell model for tumor-related research, and the action mechanism of the drug can be studied by comparing its genetic difference with the parental cell.
