Abstract:Objective: To study on the chemical constituents of Lavandula augustifolia. Method: The compounds were extracted with 95% ethyl alcohol, isolated by various column chromatography and identified by spectroscopic methods. Result: Seven flavanoids were isolated and identified as apigenin (1), ladanein (2), apigenin-7-O-β-D-(6′-p-hydoxy-cinnamoyloxy)-mannoside (3), luteolin (4), apigenin-7-O-β-D-glucoside (5), luteolin-7-O-β-D-glucoside (6), 5, 4′-dihydroxy flavonoid-7-O-β-D-pyranglycuronate buthyl ester (7). Conclusion: All of these seven compounds were obtained from this plant for the first time.
