Abstract: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.
Keywords:Gueldenstaedtia stenophylla   Chemical constituents   Structure determination
