Chromone C-glycosides from Baeckea frutescens

Five new chromone C-glycosides have been obtained from the leaves of Baeckea frutescens. They are: 6-β-C-glucopyranosyl-5,7- dihydroxy-2-isopropylchromone, 8-β-C-glucopyranosyl-5,7-dihydroxy-2-isopropylchromone, 6-β-C-glucopyranosyl-5,7-dihydroxy- 2-methylchromone, 6-β-C-(2′-galloylglucopyranosyl)-5,7-dihydroxy-2-isopropylchromone and 8-β-C-(2′-galloylglucopyranosyl)-5,7-dihydroxy-2-isopropylchromone.
