摘要

A new pyridine, named 4-(2′-methylpropoxyl)pyridine-2-carboxylic acid (mengyunine) (1) as well as 1′-(7-methoxybenzo[d][1,3]dioxol-5-yl)butan-1′-ol (2), 4,7-dimethoxy-5-(propanoyl)benzo[d][1,3]dioxole (3), scopoletin (4), aesculetin dimethyl ester (5), xanthyletin (6), demethylluvangetin (7), chromenylacrylic acid (8), apigenin (9), luteolin (10), ferulic acid (11), methyl ferulate (12), methyl caffeate (13), 3′,4′,5′-trimethoxycinnamyl alcohol (14), methyl indole-3-carboxylate (15), picolinic acid (16), and 3-methylpicolinic acid (17), were isolated from the MeOH extract of the roots of Foeniculum vulgare. The structure of the new pyridine was elucidated by chemical and physical evidence.
