[Studies on the chemical constituents of Rubus parvifolius].

ABSTRACT

OBJECTIVE: To study the chemical constituents of Rubus parvifoliu. METHODS: The constituents were isolated by column chromatography and their structures were elucidated through spectroscopic analysis such as 1H-NMR, 13C-NMR, FT-IR, et al. RESULTS: Seven compounds were isolated from the roots of Rubus parvifolius L., they were identified as p-sitosterol (I), lauric acid (II), O-nitrophenol (III), beta-daucosterol (IV), euscaphic acid (V), camelliagenin A (VI) and(+) -catech in (VII). CONCLUSION: Compounds III and VII are isolated from the plant for the first time.
