Title Direct emission of the allergen primin from intact Primula obconica plants
Bibliographic information Mar. 2000, Vol.42, No.3, p.149-153. Illus. 24 ref.
Abstract The allergen primin and its precursor miconidin were collected by dynamic headspace technique from the glasshouse plant Primula obconica Hance and quantified and identified by gas chromatography and gas chromatography-mass spectrometry. The primin concentrations in leaves/stems and flowers of P. obconica were 262µg and 531µg per g fresh plant material, respectively, whereas miconidin concentrations were 92µg per g fresh plant material in leaves and stems and 194µg per g fresh plant material in flowers. The amounts of primin released from unchopped leaves/stems and flowers were 65.3ng and 18.8ng per g fresh plant material per hour, respectively. Dynamic headspace analysis of intact P. obconica plants showed that primin is also directly emitted from undamaged plants, although in smaller concentrations, whereas miconidin was only emitted in minute amounts. The possibility that primin from P. obconica could be a potential airborne allergen and therefore a source of airborne contact dermatitis is discussed.
