A novel sesquiterpenoid was isolated from the whole plant of Ecdysanthera rosea Hook. et Arn. Its structure was elucidated as tricyclo[5,3,1,02,4]-3-aldehyde-3,11-dimethyl-8-methanoic acid on the basis of spectral evidence (1D and 2D NMR) and was named ecdysanthblic acid. [ABSTRACT FROM AUTHOR]

The interaction of the polysaccharide of Limonium bicolor with BSA was measured at a neutral pH and an ionic strength of 0.15 M(NaCl), using SDS-PAGE and UV-Vis and fluorescence spectroscopy. The moving speed, the absorbance value, and the fluorescence of BSA are changed when glycan is present. The results have shown that the interaction is taken between glycan and BSA.
