Evaluation of “Dream Herb,” Calea zacatechichi, for Nephrotoxicity Using Human Kidney Proximal Tubule Cells

Figure 1

Extracted total compound chromatogram from chemical characterization of the C. zacatechichi extract by LC-high resolution mass spectroscopy. Putative compound identification was made by matching exact mass with that of known components of C. zacatechichi [8, 30–33]. (1) Ciliarin, (2) zexbrevin, (3) sesquiterpene lactone, (4) calein D, (5) 1-β-acetoxyzacatechinolide, (6) calein A, (7) 1-oxo-zacatechinolide, (8) calealactone E, (9) calealactone, and (10) acetoxycaleculatolide.
