The leaves of <i>Castanopsis sieboldii</i> (Fagaceae) contain characteristic hexahydroxydiphenoyl (HHDP) esters of 28-<i>O</i>-glucosyl 2α,3β,23,24-tetrahydroxyolean- and urs-12-en-28-oic acids. In this study, uncharacterized substances were detected in the young leaves, which are not observed in the mature leaves. Preliminary HPLC analyses indicated that the substances had dehydro-HHDP (DHHDP) ester groups; however, the esters were unstable and decomposed during extraction. Therefore, the compo ...[more]
