Stability of the β-sitosterol glycoside from Schima wallichii sp. liukiuensis at various physical conditions were investigated, mutagenecity of the steroid saponin was determined by Ames test. When exposed in pH 3 to pH 8, the β-sitosterol glycoside was stable on antimicrobial activity against yeasts. The antimicrobial activity of the β- sitosterol glycoside also stable in high temperature, N₂, O₂ gas and light exposure, and metal ion. Ames test result revealed that (β-sitosterol glycoside did not have any mutagenic activity. These results suggest that the β-sitosterol glycoside might be a promising candidate as a natural antimicrobial compound.
