Solubilizing properties of saponins from Sapindus mukurossi Gaertn.

Abstract

Mukurozi-saponins Y1 and Y2, bisdesmosides from pericarps of Sapindus mukurossi, greatly increased the water solubilities of the co-occuring monodesmosides. The mode of solubilizing properties of these saponins were investigated. The bisdesmosides also increased the solubilities of Yellow OB and Progesterone in phosphate buffer.
