    • The mixture generated via random glycosylation usually composed of a series of isomeric compounds, which made the isolation of individual chemicals extremely difficult. Moreover, the deconvolution of the library was also a complicated course if the active compounds needed to be identified.

    • Petroleum ether-EtOAc (6:1, v/v) was used to collect the fractions including all the possible bisdesmosidic glycosides. Afterwards minor monodesmosidic saponins were eluted by petroleum ether-EtOAc (3:1, v/v), followed by the fraction of starting kryptogenin with a recovery of 10%.

    • We also attempted to use three glycosyl donors in one random reaction. Unfortunately, the corresponding sublibrary generated was too complex to be analyzed and separated. So far, at best three components are suitable in our research.
