Objective:
To study the flavonoids from the leaves of Santalum album.
Method:
The sample was extracted with 70% ethanol by continuous thermal reflux. The extraction was separated and purified by column chromatography over macroporous adsorption resin, polyamide and sephadexlh-20. Their structures were identified by detailed spectroscopic analysis.
Result:
Eight flavonoids were isolated and identified as vicenin-2 (1), vitexin (2), isovitexin (3), orientin (4), isoorientin (5). chrysin-8-C-beta-D-glucopyranoside (6), chrysin-6-C-beta-D-glucopyranoside (7), and isorhamnetin (8).
Conclusion:
All compounds were isolated from this plant for the first time.
