Abstract:
Cultured suspension cells of Eucalyptus perriniana converted exogenously administered alpha-tocopherol into alpha-tocopheryl 6-O-beta-d-glucopyranoside (46mug/gfr. wt of cells) and two biotransformation products: alpha-tocopheryl 6-O-(6-O-beta-d-glucopyranosyl)-beta-d-glucopyranoside (19mug/gfr. wt of cells) and alpha-tocopheryl 6-O-(6-O-alpha-l-rhamnopyranosyl)-beta-d-glucopyranoside (6mug/gfr. wt of cells). On the other hand, two other compounds, i.e., delta-tocopheryl 6-O-(6-O-beta-d-glucopyranosyl)-beta-d-glucopyranoside (27mug/g fr. wt of cells) and delta-tocopheryl 6-O-(6-O-alpha-l-rhamnopyranosyl)-beta-d-glucopyranoside (12mug/g fr. wt of cells), together with delta-tocopheryl 6-O-beta-d-glucopyranoside (63mug/g fr. wt of cells) were isolated from suspension cells following the administration of delta-tocopherol.
