1H-NMR spectra were recorded in CDCl3 on Burker
spectrometer, operating at 400 MHz at 25 AdegC.
ECs were harvested using x1 trypsin-ethylenediaminetetraacetic acid (Life Technologies, USA), washed with endothelial growth medium-2 (EGM-2) medium, centrifuged at 180 xg for 5 min in a 14-ml Falcon tube (Becton-Dickinson Labware, USA), and counted in a Burker

By counting unstained cells using a Burker
chamber we showed that homochelidonine decreased the proliferation of Jurkat cells within 48 h of treatment with [IC.
After the incubation, cells were detached enzymatically, counted using the Burker
chamber, and the number of population doublings (the measure of cell proliferation) was calculated using the following formula: population doublings = [log.
