Objective: To isolate and elucidate the constituents from rhizome of Arundina graminifolia. Method: The constituents were extracted with 95% alcohol and isolated by chromatography on silica gel, Sephedax LH-20. The structures were determined by UV, IR, NMR and MS spectral analysis. Result: Five phenanthrene constituents were identified as 7-hydroxy-2, 4-dimethoxy-9, 10-dihydrophenanthrene (I), 4,7-dihydeoxy-2-methoxy-9, 10-dihydrophenanthrene (II), 2, 7-dihydroxy-4-methoxy-9, 10-dihydrophenanthrene (III), 7-hydroxy-2-methoxyphenanthrene-1,4-dione (IV), 7-hydroxy-2-methoxy-9,10-dihydrophenanthrene-1,4-dione (V), respectively. Conclusion: All compounds were isolated from rhizome of A. graminifolia for the first time.
