Tujuan dari penelitian ini adalah untuk menguji tingkat sitotoksisitas dan genotoksisitas senyawa metabolit sekunder dalam fraksi-fraksi ekstrak etanol R. stylosa terhadap akar dan kromosom tanaman bawang A llium cepa . Penelitian ini menggunakan metode eksperimental dengan Rancangan Acak Lengkap (RAL), melibatkan sebelas fraksi dengan konsentrasi seragam (125 ppm), serta kontrol negatif berupa larutan akuades dan kontrol positif berupa larutan EMS, dengan dilakukan sebanyak 3 kali pengulangan. Parameter yang diobservasi meliputi indeks mitosis, pertumbuhan akar bawang, dan aberasi kromosom. Hasil pengamatan dianalisis menggunakan ANOVA Ft(α.05) dan uji lanjutan Duncan Ft (α.05). Hasil pengujian sebelas fraksi dengan konsentrasi 125 ppm menunjukkan penurunan nilai indeks mitosis yang bervariasi, serta terdeteksi adanya aberasi kromosom dengan frekuensi yang beragam. Meskipun demikian, sebelas fraksi tidak menunjukkan sifat subletal maupun letal terhadap indeks mitosis. Jenis aberasi kromosom yang teramati meliputi anaphase spindle break, ball metaphase, break, bridge, c-mitosis, delayed anaphase, diagonal anaphase, disorder of chromosome kinetic, double bridge, double lesion, fragment, giant cell showing polyploidy, laggard, micronucleus, nuclear erosion, nuclear extrusion, ring, star, stickiness , dan vagrant .

This study aims to examine the cytotoxicity and genotoxicity of secondary metabolite compounds from fractions of R. stylosa ethanolic leaf extract on the roots and chromosomes of A. cepa onions. The study was conducted using an experimental method with a Completely Randomized Design (CRD), the treatment of eleven fractions with one 125 ppm for all fractions, and negative control of distilled water solution and positive control of EMS solution, with 3 repetitions for each treatment. The parameters observed were mitotic index, onion root growth and chromosomal aberration. The observations were analyzed with ANAVA Ft (α.05) and followed by Duncan Ft test (α.05). The results of eleven fractions with a concentration of 125 ppm showed a decrease in the value of various mitotic indices and the discovery of chromosome aberrations with varying frequencies.
