1The Key Laboratory of Bioorganic Chemistry and Molecular Engineering, Ministry of Education, College of Chemistry and Molecular Engineering, Peking University, Beijing 100871, China.
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-beta-D-(6'-p-hydoxy-cinnamoyloxy) -mannoside (3), luteolin (4), apigenin-7-O-beta-D-glucoside (5), luteolin-7-O-beta-D-glucoside (6), 5, 4'-dihydroxy flavonoid-7-O-beta-D-pyranglycuronate buthyl ester (7).
Conclusion:
All of these seven compounds were obtained from this plant for the first time.
