Abstract
Two new phenylalkanoids, 5-hydroxy-1-(4′,5′-dihydroxy-3′-methoxy-phenyl)-decan-3-one (1) and 1-(4′,5′-dihydroxy-3′-methoxy-phenyl)-dec- 4-en-3-one (2), were isolated from the rhizomes of Chinese ginger (Zingiber officinale Roscoe (Zingiberaceae)). The structures of these new phenylalkanoids were elucidated by chemical and physical evidence.
