Abstract

From Myrica gale var. tomentosa, two new diarylheptanoids, myricatomentosides I and II, were isolated together with a plane-chiral diarylheptanoid, galeon. The absolute stereochemistry of (+)-galeon was determined as R. Myricatomentoside I, was identified as the glucoside of myricatomentogenin, a new diarylheptanoid of diphenyl ether type, and myricatomentoside II, as the glucoside of 12-hydroxymyricanone.
