 Title    Populus cathayana and Populus szechuanica  
 Abstract    Analysis o f GC-M S data revealed 58 com ponents o f bud exudate from P. cathayana (Section Tacamahaca) and 40 com ponents o f bud exudate from P. szechuanica (Section Tacamahaca) o f which 47 and 35 respectively were phenolics. The bud exudates were very similar in com position, containing flavanones and chalcones (61 % and 51% respectively), flavones (15% and 12%) and pentenyl caffeates (11 % and 6%). The major single com ­ ponent o f the exudate o f both poplars was pinobanksin-3-acetate (26% and 33%). The bud exudates o f P. ca­ thayana and P. szechuanica are similar to those o f Euro­ pean and American Section Aigeiros poplars and unlike those o f North American Section Tacamahaca poplars.

 Title      
 Abstract    Analysis of bud exudate of Populus violascens by GC-MS identified 26 phenolic components. The bulk of the exudate was composed of caffeic acid esters.

 Title      
 Abstract    Analysis by GC-MS identified 30 phenolic compo­ nents of the bud exudate of P. laurifolia. The majority of the exudate was composed of flavanones, flavanonols and chalcones, with pinobanksin-3-acetate being the major component. The bud exudate resembled that of the Asian Section Tacamahaca poplars P. cathayana and P. szechuanica but was unlike that of the North Ameri­ can Section Tacamahaca poplars, P. balsamifera and P. trichocarpa.

 Title    Com position o f Propolis from Two Different Spanish Regions  
 Abstract    Propolis and propolis balsam from two different Spanish Regions were analyzed by GC-MS. The majori­ ty of the compounds were typical of poplar bud exudate of P. nigra. N o significant differences were found be­ tween the balsam and the entire propolis analyzed, apart from the components of beeswax added to the plant exu­ date by the bees.
