results obtained showed that compounds 5h, 5i, and 5n exhibited significant cytotoxicactivities against the six cell lines, being more potent than their parent compound sarsasapogenin. Furthermore, the p-fluorobenzyloxy series of compounds generally exhibited stronger cytotoxicities against all the tested cancercells compared with the benzyloxy and p-methoxybenzyloxy series, and the substitution of pyrrolidinyl
