The inducer of differentiation of human promyelocytic leukemia HL-60 cells is commonly accepted to have potential therapeutic importance. Verticinone, one of the major isosteroidal alkaloids from the bulbus of Fritillaria ussuriensis, was found to inhibit the growth of HL-60 cells by inducing these
Although verticinone, a major alkaloid isolated from the bulbus of Fritillaria ussuriensis, has been shown to induce differentiation in human leukemia cells, the exact mechanism of this action is not completely understood in cancer cells. Verticinone was used to conduct growth and apoptosis-related
Bioassay-guided fractionation of the BuOH-soluble extract of Fritillaria ussuriensis afforded verticinone ( 1), verticine ( 2), and peimisine ( 3). Purification of these compounds was achieved with the use of various chromatographic methods. The structures of the compounds were identified on the
Methods based on triple quadrupole tandem mass spectrometry have been widely used and reported as highly selective and sensitive methods for quantifying substances of herbal medicines. However, most of them were limited to targeted components, due to the difficulties to optimize the multiple
