Stephania sinica

Runanine (17) was isolated from the roots of Stephania sinica, a species found in the Chinese provinces of Heibei, Gueizhou, and Yunnan (35). The H-NMR spectrum of runanine (17) (Table II) revealed the presence of two aromatic protons, C-5 methylene protons, one N-methyl, and four methoxyl groups. An NOE effect (10% enhancement) was observed between the protons of two methoxyl groups (53.79 and 3.80) and the aromatic protons (56.47 and 6.64), but the same phenomenon was not observed for the other methoxyl protons (53.61 and 4.05). Therefore, the former methoxyls should be situated on ring A. From the further observation of an NOE (22.6% enhancement) between the aromatic C-4 proton (56.64) and one (53.00) of the C-5 methylene protons, it was assumed that the two methoxyl groups (53.79 and 3.80) should be located at C-2 and C-3, respectively. The absence of signals for olefinic...
