Myricarborin A and n-butyl-alpha-L-rhamnopyranoside, two novel compounds from the bark of Myrica rubra

From the bark of Chinese Myrica rubra (Myricaceae) two novel compounds, myricarborin A and n-butyl-alpha-L-rhamnopyranoside, have been isolated along with (+)-S- myricanol, (-)-R- myricanol 5-O-beta-D-(6'-O-galloyl)-glucopyanoside and n-butyl-beta-D-fructopyranoside. The structures of the novel compounds were determined by spectroscopic methods.
