【 摘 要 】

From leaves of Guarea kunthiana one new kaurene diterpene (ent-kaur-16-en-2-one) was isolated along with eight known diterpenes (ent-kaur-16-ene, ent-3a- and 3b-hydroxykaur-16-ene, kolavelool, kolavenol, kolavenal, ent-13-epi-manoyloxide and (-)-nephthenol), four sesquiterpenes (alismol, alismoxide, spathulenol and 4b,10a-aromadendranediol), polyprenol-12 and a- and d-tocopherols. Kolavenal is reported for the first time as a natural product, as well as the occurrence of cembrane- and ent-kaurane-type diterpenes in the Meliaceae.
