Six flavonoids were isolated from Brickellia arguta and identified using chemical and spectral methods. The isolation and spectral data of a new flavonoid, 6- methoxykaempferol 3-O-beta-D- robinobioside (3), are reported for the first time. Three of these flavonoids were tested and showed inhibition
Chemical fractionation of Brickellia paniculata methanolic extract by monitoring its inhibitory effect on K(+)-induced contraction in guinea-pig ileum in vitro led to the isolation of 5,4'-dihydroxy-6,7,8-trimethoxyflavone (xanthomicrol) and the labdane-diterpene 3 alpha-angeloyloxy-2
An aqueous extract from the aerial parts of Brickellia cavanillesii attenuated postprandial hyperglycemia in diabetic mice during oral glucose and sucrose tolerance tests. Experimental type-II DM was achieved by treating mice with streptozotocin (100 mg/kg) and β-nicotinamide adenine dinucleotide
