Objective: To study the chemical constituents of the corm of the planted Cremastra appendiculata.
Method: The compounds were isolated by column chromatography with silica gel and Sephadex LH-20, and their structures were elucidated by means of spectroscopic methods including 2D NMR techniques.
Result: Six compounds were isolated, and identified as isohircinol (I), flavanthrinin (II), p-hydroxyphenylethyl alcohol (III), 3,4-dihydroxyphenylethyl alcohol (IV), daucosterol (V), beta-sitosterol (VI).
Conclusion: These compounds were not previously isolated from this plant, and isohircinol (I) was obtained from natural source for the first time.
