Triterpene saponins in the roots of Beta vulgaris cultivars Red Sphere, Rocket, and Wodan were profiled and quantitated using reverse-phase liquid chromatography coupled with electrospray ionization mass spectrometry (HPLC-ESI/MS/MS). Results obtained indicated that the roots of all three cultivars contained 11 saponins consisting of oleanolic acid or hederagenin aglycone and varying numbers of sugars, with the dominant triglycoside derivative of oleanolic acid. The relative proportions of derivatives of these two aglycones were similar in the three subspecies: cv. Red Sphere contained 99.1 and 0.9%; cv. Rocket, 98.2 and 1.8%; and Wodan 98.8 and 1.2% of oleanolic acid and hederagenin glycosides, respectively. To the best of our knowledge this is the first report on the occurrence, structure, and content of triterpenoid saponins in red beet.
