title: Alkaloids from the roots of Zanthoxylum nitidum and their antiviral and antifungal effects.
abstract: Five alkaloids, 5,6-dihydro-6-methoxynitidine (1), dictamnine (2), gamma-fagarine (3), skimmianine (4), and 5-methoxydictamnine (5), were isolated from the roots of Zanthoxylum nitidum. Their structures and configurations were elucidated by spectroscopic methods and X-ray analysis. Compounds 1, 4, and 5 showed in vitro antiviral effect against hepatitis B virus, and compounds 2, 3, and 5 demonstrated marked antimitotic and antifungal activity.
