Triterpenoid Profile of A. annua Anamed A3 and Meise Cultivars.

(A) and (B) Overlay of GC-MS chromatograms of extractions from flower buds (A) and leaves (B) of Anamed A3 (black) and Meise (green) cultivars.

(C) Overlay of GC-MS chromatograms of authentic standards of β-amyrone (green), β-amyrin (pink), α-amyrone (blue), and α-amyrin (black). The abundant triterpenes and triterpenoids are indicated on the chromatograms, and their EI-MS spectra are given in Supplemental Figure 1. The GC retention times of β-amyrone, δ-amyrin, β-amyrin, α-amyrone, and α-amyrin are 26, 26.2, 26.5, 27.5, and 27.9 min, respectively.
