GC-MS Analysis of the Dichloromethane Extract of the Bulbs of Ornithogalum cuspidatum Bert. (Family: Liliaceae) from Iran

The gas chromatography-mass spectrometry (GC-MS) analysis of the vacuum liquid chromatographic (VLC) fractions of the dichloromethane (DCM) extract of the bulbs of Ornithogalum cuspidatum, a native perennial of Iran , Iraq and Turkey , led to the identification of a number of steroidal compounds. The free radical scavenging activity of the DCM extract was assessed by the 2,2-diphenyl-1-picryl hydrazyl (DPPH) assay, and found to be much weaker (RC 50 = 0.5197 mg/mL) than that of the positive control Trolox ® (RC 50 = 3.07 x 10 -3 mg/mL).
