Abstract:
In addition to the three known daucane esters (2,3,8) and one phenylpropanoid (9), the petroleum ether extract of the roots of Ferula tingitana yielded four new daucane esters: 14-p-anisoyloxy-dauc-4,8-diene (1), acetyltingitanol (4), acetyldesoxodehydrolaserpitine (5), and 4-beta-hydroxy-6-alpha-p-hydroxybenzoyloxy-10-alpha-angeloyloxy dauc-8-ene (6). A possible biogenetic pathway for 1,5-cis- and 1,5-trans-daucanes is presented.
