Abstract

Tuduranine (Na) was isolated from the root tuber of Stephania rotunda Loureno and was identified. Stepharine (Ⅱ) was heated with 3N sulfuric acid and tuduranine was obtained by the dienone-phenol rearrangement which proved that the absolute configuration of tuduranine is represented by the formula Na.
