[Studies on chemical constituents from rhizomes of Hedychium chrysoleucum].

OBJECTIVE

To investigate the chemical constituents from the rhizome o fHedychium chrysoleucum.

METHOD

The compounds were isolated by column chromatography on silica gel. The structures were identified by NMR, IR and MS analyses.

RESULT

Seven compounds were isolated and identified as hedychenone (1), coronarin A (2), yunnancoronarin A (3), coronarin E (4), beta-sitosterol (5), cryptomeridiol (6), and beta-eudesmol (7).

CONCLUSION

Compounds 1-7 were obtained from this plant for the first time.
