Objective:
To study the chemical constituents of Gueldenstaeditia stenophylla.
Methods:
The constituents were isolated by alcohol extraction, column chromatography on silica gel. Their structures were elucidated by chemical and spectroscopic methods.
Results:
Six compounds were obtained, and five of them were identified as n-hexadecanioc acid (I), beta-sitosterol (II), daucosterol (III), apigenin (IV), D-fructose (VI). Compound V was being determined.
Conclusion:
Five compounds are isolated from Gueldenstaedtia stenophylla and compounds I, III are extracted from Gueldenstaedtia Fisch for the first time.
