✦ Synopsis

The essential oil from the rhizomes of Hedychium gardnerianum Roscoe (`Kahili ginger') contains about 30% of sesquiterpenes, mainly cadinane derivatives. The following new sesquiterpenes were identi®ed by their NMR and MS data: a-corocalene epoxide (104); 1,10;7,10-bisepoxy-1,10-seco-calamenene (68); 6,7;7,10bisepoxy-6,7-seco-calamenene (74); 7-epi-trans-(60) and 7-epi-cis-sesquisabinene hydrate (69); 10-epi-cubenol (78); and ar-curcumen-1,10-diol (108).
