Twelve phenolic compounds were isolated from I. cylindrica var. major and identified as 4,7-dimethoxy-5-methylcoumarin (1), 7-hydroxy-4-methoxy-5-methylcoumarin (2), 7- O-β- D-glucopyranosyl-4-methoxy-5-methylcoumarin (3), 6-hydroxy-5-methoxyflavone (4), 5-methoxyflavone (5), 5,7-dihydroxy-8-methoxyflavone (6), 4-hydroxybenzaldehyde (7), 4-hydroxy-cinnamic acid (8), 4-hydroxy-3-methoxybenzoic acid (9), 3,4-dimethoxyphenyl- O-β- L-rhamnopyranosyl-(1β6)-β- D-glucopyranoside (10), impecyloside (11), and graminone A (12).
