terutama pada wanita. Pengobatan terkait kanker yang efektif dan aman masih terus&#13;
dikembangkan, salah satunya dengan bahan alami. Rubus fraxinifolius merupakan salah&#13;
satu tanaman yang berpotensi sebagai tanaman obat. Penelitian ini bertujuan untuk&#13;
mengetahui pengaruh pemberian ekstrak diklorometan ranting tanaman R. fraxinifolius&#13;
terhadap viabilitas sel kanker payudara lini sel MCF-7 secara in vitro. Hasil analisis GCMS&#13;
menunjukkan bahwa ekstrak diklorometan ranting R. fraxinifolius mengandung&#13;
beberapa senyawa metabolit sekunder seperti asam lemak, fenolik, flavin, dan pyranone,&#13;
Sel MCF-7 dikultur dan diberi perlakuan ekstrak dengan konsentrasi 5000 ppm, 1250 ppm,&#13;
625 ppm, dan 312,5 ppm. Setelah sel MCF-7 diberi perlakuan dan diinkubasi selama 24&#13;
jam, selanjutnya melakukan analisis uji sitotoksik dengan metode MTT assay. Nilai&#13;
absorbansi diukur menggunakan ELISA reader dan dianalisis untuk membuat kurva dosisrespon&#13;
serta menentukan nilai IC50. Hasil penelitian menunjukkan ekstrak diklorometan&#13;
ranting R. fraxinifolius memiliki nilai IC50 &gt;5000 μg/mL. Meskipun demikian, ekstrak ini&#13;
menunjukkan pengaruh terhadap viabilitas sel MCF-7 yang ditandai dengan peningkatan&#13;
presentase inhibisi seiring dengan peningkatan konsentrasi. Sehingga ekstrak diklorometan&#13;
ranting R. fraxinifolius memiliki potensi untuk mempengaruhi pertumbuhan sel MCF-7&#13;
meskipun dengan aktivitas sitotoksik yang tergolong rendah.&#13;
