The configurations of substituted phenyl furoisoxazolines were determined by study on their 1H-NMR and 1D NOESY. The characteristic chemical shifts of the g-lactone ring protons in 1H-NMR were also discussed.
Two new compounds, oleanolic acid 28-O--D-glucopyranosyl-3-O--L-arabinopyrano- syl-(13)-(6-butyl ester)--D-glucuropyranoside 1, oleanolic acid 28-O--D-glucopyranosyl- (16)--D-glucopyranoside 2 have been isolated from ...Two new compounds, oleanolic acid 28-O--D-glucopyranosyl-3-O--L-arabinopyrano- syl-(13)-(6-butyl ester)--D-glucuropyranoside 1, oleanolic acid 28-O--D-glucopyranosyl- (16)--D-glucopyranoside 2 have been isolated from the roots of Hemsleya penxianensis var. gulinensis. Their structures were determined on the bases of the spectral and chemical evidences.展开更多
UV-vis and luminescence spectroscopic titration experiments show that a novel Ru(II) complex exhibits off-on-off pH luminescent switching with a maximum on-off ratio of about 100.

The agent technology is combined with petri net in order to enhance flexibility and extendibility, and the agent-oriented single token and colored transition petri net is proposed. Some characteristics such as liveness, fairness and safety are analyzed. Finally, an example in mould agile manufacturing is given to illustrate the use of it.展开更多
