Steam explosion process was applied to extraction of Phellodendron bark. Although Phellodendron bark is a fibrous bark crude drug hard to be milled, the steam-exploded Phellodendron bark was easily crushed to broken tissues. The extraction yields of the extract and of berberine from the low pressure steam-exploded bark were higher than those from untreated barks. The constituents of the extract, however, varied depending upon the processing steam pressure. The viscosity of the aqueous extract from the steam-exploded bark was lower, which resulted in easier filtration and improvement of extraction of its components. The steam-exploded bark was more brown and had a burnt smell, but steam-explosion, in particular of lower steam pressure, is considered to be useful pretreatment for efficient extraction.
