[Chemical constituents of n-BuOH extract from Phyllanthus matsumurae].

OBJECTIVE: To study the chemical constituents of n-BuOH extract from Phyllanthus matsumurae. METHODS: Column chromatography was used for the isolation and purification. Spectroscopic methods including H-NMR, 13C-NMR and MS were used for the identification of structures. RESULTS: Six compounds were isolated from the n-BuOH extract of 75% alcohol extract of the whole plant and identified as ellagic acid (1), phyllanthuspermin B (2), phyllanthuspermin C (3), xanthoxylin (4), hesperetin-7-O-[6-O-(alpha-L-rhamnopy ranosyl)] -beta-D-glucopyranoside (5) and 4-O-methylgallic acid (6). CONCLUSION: Compounds 2 - 6 are obtained from this plant for the first time.
