Separation and detection of group A saponins, Ab and Af, by thin layer chromatography (TLC) and DDMP saponin βa by high performance liquid chromatography (HPLC). A: TLC patterns of aqueous 70% ethanol extracts of seed hypocotyls. Ab: Fukuyutaka (Ab phenotype, Sg-3), Af: Mikuriya-ao (Af phenotype, sg-3). Arrows indicate the positions of respective group A saponins. Rf: relative to front. B: HPLC chromatograms of the extracts. Upper: Ibarakimame 7 (βa presence, Sg-4), lower: Suzuyutaka (βa absence, sg-4).
