Induction of Apoptosis in Human Breast Cancer Cells via Caspase Pathway by Vernodalin Isolated from Centratherum anthelminticum (L.) Seeds
Figure 5
Mass spectra of CACF isolated fractions.
(A, B) LC-MS chromatograms of fraction CACF-A and CACF-C. (A) Single peak detected in the fraction CACF-A was identified as vernodalin (1). (B) Major peak detected in fraction CACF-C was identified as 12,13-dihydroxyoleic acid (2) while vernodalin (1) constituted a small part in the fraction. (C) HR-ESI-MS spectrum (positive mode) of vernodalin (1). (D) HR-ESI-MS spectrum (negative mode) of 12,13-dihydroxyoleic acid (2).
