From the roots of Codonopsis pilosula (Franch.) Nannfeldt (Campanulaceae), ${alpha}$-spinasterol, mp $165{sim}7^{circ}$ and alpha-spinasteryl D-glucoside, mp $283{sim}5^{circ}$, were isolated and identified on the basis of chemical and spectral data. Spectral data showed that $Delta^7-stigmasterol$ and its glucoside were contained as minor components.
