Identification of neolignan SC(4-O-8)G (1) in Arabidopsis seeds. UPLC chromatograms (A) and MS/MS spectra (B) of synthetic standards of erythro-SC(4-O-8)G (1e) and threo-SC(4-O-8)G (1t) and the corresponding product from Col-0 are shown. The structural interpretation of fragment ions was shown in Böttcher et al. (2008). (C) Structures of synthetic 1e and 1t. *Synthetic 1e (RT 7.63 min) and 1t (RT 8.10 min) are each racemic mixtures. Only the (7S, 8R) enantiomer of 1e and the (7R, 8R) enantiomer of 1t are depicted. RT, retention time.
