Phytochemistry,1994,37(5): 1383-1388. | Labdane diterpenes from rhizomes of Hedychium coronarium[Reference: WebLink] |
METHODS AND RESULTS:
Three new labdane diterpenes were isolated together with four known diterpenes [(E)-labda-8(17),12-diene-15,16-dial, Coronarin B and D, and isocoronarin D] from rhizomes of Hedychium coronarium.
CONCLUSIONS:
The structures of the new compounds were determined by spectroscopic evidence to be labda-8(17), 11,13-trien-15(16)-olide, an ester of labda-8(17), 11,13-trien-15-al-16-oic acid and isocoronarin D, and 7β-hydroxyCoronarin B.

METHODS AND RESULTS:
Four new labdane-type diterpenes, Coronarin A, Coronarin B, Coronarin C, and Coronarin D, and one known labdane-type diterpene, (E)-labda-8(17), 12- diene-15, 16-dial were isolated as cytotoxic prinicples from the rhizomes of Hedychium coronarium, Zingiberaceae. The structures were established by chemical and spectroscopic methods. |
