Anti-leukemia steroidal saponins from Paris polyphylla var. yunnanensis
PhytochemistryFrom the rhizomes of Paris polyphylla var. yunnanensis (Franch.) Hand.-Mazz., five novel steroidal saponins (Polyphyllozsides A-E, 1-5) and four known steroidal saponins (6-9) were isolated. The biological activities of the nine compounds against human hematologic malignancy cell lines (U-937, THP-1 and Jurkat) was evaluated using a cytotoxicity assay.
