Separation curves of limonene (▲) and α-terpineol (■) in the oily fraction resulting from the biotransformation of (A) R-(+)- and (B) S-(–)-limonene. This procedure was carried out in an open column (37 mm diameter × 15 cm stationary phase) containing activated (105 °C/3h) silica gel 60 eluted with hexane:ethyl acetate (9:1).
