Two new yuzurine alkaloids, daphnoldines A ( 1 ) and B ( 2 ), possessing a rare four‐ring system, were isolated from the fruits of Daphniphyllum oldhami. Their structures were established on the basis of extensive spectroscopic analyses. Daphnoldine A ( 1 ) is the first example of Daphniphyllum alkaloids bearing a hydroxymethyl group at C(14).
