Compound 15 (skyrin) exhibited significant growth inhibition across HeLa, Vero, K562, Raji, Wish, and Calu-1 cell lines.

Compounds 3 (2-hydroxyemodin 1-methyl ether) and 10 (emodin) inhibited the proliferation of most tested tumor cell lines, excluding K562.

Conclusions:

Ventilago leiocarpa is a rich source of structurally diverse anthraquinones.
Compound 15 demonstrates potent broad-spectrum anticancer activity, warranting further investigation.
Compounds 3 and 10 also possess significant cytotoxic properties against specific cancer cell types.
