摘要：

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