  摘要：

  A new sesterterpene, (2Z,6Z, 10E)-cericerene-15,24-diol (1), and its 30-hydroxytriacontanoate (2) were isolated from the wax exuded by the scale insect Ceroplastes pseudoceriferus, together with the acetates and 30-hydroxytriacontanoates of 3,15-dihydroxy- and 15,20-dihydroxylabda-7,13-diene (3-6). The absolute configurations of the labdadiene alcohols were antipodal to the ordinary labdanes isolated from terrestrial plants.
