Abstract:

Chemical constituents of leaves of Allium sativum L. were isolated and purified by column chromatography and their structures were elucidated on the basis of spectral analyses. 10 compounds were obtained and identified as S-(+) dehydrovomifoliol (Ⅰ), (+) vomifoliol (Ⅱ), N-transferuloyl-3′-methoxytyramine (Ⅲ), N-cis-feruloyl3′-methoxytyramine (Ⅳ), N-trans-p-coumaroyltyramine (Ⅴ), N-cis-p-coumaroyltyramine (Ⅵ), N-trans-p-coumaroyl octopamine (Ⅶ), N-cis-p-coumaroyl octopamine (Ⅷ), 4-hydroxybenzoic acid (Ⅸ), 3,4-dihydroxybenzoic acid (Ⅹ). Compounds Ⅰ～Ⅵ and Ⅷ  wereisolated from this plant for the first time.

Key words: Allium sativum L. leaves; chemical constituents
