Objective:
To isolate and elucidate the constituents from rhizome of Arundina graminifolia.
Method:
Theconstituents 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-dihydroxy-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.
