The saponin contents have only previously been reported for A. macroacantha, and as a consequence, simultaneous dereplication has been performed on saponin-rich fractions from the other plants by mass spectrometry (MS) and nuclear magnetic resonance (NMR) spectroscopy. This strategy enables the identification of a total of 26 saponins, 14 of which have been described previously and 12 of which are proposed as new saponins. They include isomers and a new sugar chain with a β-d-apiofuranose unit. The method is corroborated by the isolation of eight dereplicated saponins from A. colorata. %K Agave macroacantha %K A. colorata %K A. parryi %K A. parrasana %K dereplication %K steroidal saponin %K coloratoside %K HMAI %K bioherbicide %K apiose %~ Universidad de Cádiz
