Abstract
From the stems of Myrica gale var. tomentosa (Myricaceae), a new trite rpenoid, myricalactone (1) was isolated together with serratenedione, serratenediol, myricolal and so on. The structure of 1 was determined as 19 eta-hydroxy-1,3-dioxo-oleane-11,13(18)-dien-28-oic acid 28,19-la ctone on the basis of chemical and spectrometric evidence including an X-ray crystallographic analysis of methyl ether of 1.
