OBJECTIVE
To identify whether Pulsatilla saponin A (PsA), an active molecule extracted from Pulsatilla chinensis regel, can induce acute myeloid leukemia (AML) cells differentiate.
METHODS
PsA was isolated from P. chinensis, and its effects of differentiation induction on both AML cell lines and the
Oleanane-type triterpenoid saponins from the roots of Pulsatilla koreana and their apoptosis-inducing effects on HL-60 human promyelocytic leukemia cells.

Twenty-four oleanane-type triterpenoid saponins were isolated from a methanol extract of the Pulsatilla koreana roots. Their structures were elucidated by comparing spectroscopic data to published values. Among them, compounds 8-12 and 20-24 significantly diminished the proliferation of HL-60 human
Triterpene saponins and lignans from the roots of Pulsatilla chinensis and their cytotoxic activity against HL-60 cells.

Two new triterpene saponins (8 and 9) and seven previously reported triterpene saponins (1-7) based upon oleanolic acid or hederagenin, along with two known lignans, (+)-pinoresinol (10) and beta-peltatin (11), were isolated from a saponin fraction prepared from the MeOH extract of the roots of

BACKGROUND
The rizoma of Pulsatilla chinensis (Bunge) Regel has been used as a traditional Chinese medicinal herb for thousands of years. Total saponins from P. chinensis can induce the apoptosis of solid cancer cells; however, their activity on chronic myeloid leukemia and the mechanisms remains

Two new lupane glycosides along with five known triterpenoids were isolated from the roots of Pulsatilla chinensis (Ranunculaceae). The structures of the new glycosides were determined to be 3-O-beta-D-glucopyranosyl(1-->3)-alpha-L-arabinopyranosyl-23-hydroxybetulinic acid
