  The application of Web 2.0 in high school libraries is meaningful and possible. Several application examples of Web 2.0 in the library subject service are explored. Finally, barriers and issues are studied. This research indicates that Web 2.0 can be used in subject services in four ways: to build subject communication space based on Blog and RSS; to build subject training platform based on Podcast; to build online encyclopedia of a special subject based on Wiki; to build subject repository based on Dspace.

  One new cytisine-type alkaloid, [(3-hydroxy-6-pyridinyl)-methyl]-cytisine (1), was isolated from the stem bark of Maackia amurensis, together with five known alkaloids: cytisine (2), N-formylcytisine (3), N-(3-oxobutyl)cytisine (4), (-)-epibaptifoline (5) and N-methylcytisine (6). The structure of 1 was elucidated based on spectral methods (IR, CD, 1D and 2D NMR, HR-ESI-MS and EI-MS).
