Popis:	Five new glucosylated steroidal glycosides, cantalasaponin I-B1 (1), I-B2 (2), I-B3 (3), I-B4 (4) and I-B5 (5), were isolated and purified from the transformed product of the cantalasaponin I by using Toruzyme 3.0 l as biocatalyst. Their structures were elucidated on the basis of high-resolution electrospray ionization mass spectrometry, one-dimensional (1H and 13C NMR) and two-dimensional [COSY, heteronuclear single-quantum correlation (HSQC), HMBC and HSQC-TOCSY] NMR spectral analyses and chemical evidence.
