YieldReaction ConditionsOperation in experiment
6.7% With β-glucosidase from Aspergillus niger In water at 37℃; for 3 h; Enzymatic reaction Reaction mixture (100 mL) comprising of 2.0725 g (1.5 mmol) tyrosol, 15.4 g cellobiose and Novozyme 188 (735 U of β-glucosidase) in distilled water was incubated at 37 °C. The reaction was stopped after 3 h by boiling in water bath for 5 min, centrifuged for 10 min at 4500 rpm and filtered through 0.22 m filter (25 mm diameter). The filtrate was applied on column of Sephadex LH-20 (75 cm long, 3.2 mm i.d.) equilibrated and eluted with distilled water. Tyrosol was regenerated by gradient of ethanol. The process of purification was monitored by TLC. Fractions containing salidroside were collected and concentrated in vacuo. To remove coloured substances originating from the enzyme, the material was further subjected to flash chromatography with gradient of methanol in chloroform. Fractions containing pure salidroside were concentrated and crystallised from mixture of methanol and chloroform (1:5, v/v).
