They also share a common history in the development of their devotional worship through two empresses who identified themselves with their respective cultural icon thereby enhancing their political roles while endearing themselves to the common people through their promotion of the spiritual figures of compassion. This paper seeks to show the parallels between the rise in devotion to the Virgin Mary under the Byzantine Empress Pulcheria （399-453） and the corresponding rise in the interest in, and feminization of, Avalokiteshvara/Kuan Yin under the Tang Dynasty Empress Wu Zetian （625-705）. While there has been a substantial amount written about how ancient political leaders used selected deities as vehicles for asserting their power, there are only a few that have looked at these two unique Empresses and none that compares their influence in the popularization of devotional worship to Mary and Kuan Yin. This study attempts to begin to fill that gap.展开更多

The structures of the fructans were determined by methylation, reductive-cleavage method combined with GC-MS analysis, and 13C NMR spectroscopy. These results show that the fructans (CoPS1, CoPS2 and CoPS3) are graminan type fructans, and comprised of (2→1)- and (2→6)-linked β-D-fructofuranosyl backbone residues containing high branches.展开更多
