RESUMEN
Objective To investigate the application of of Gaussian 09/GuassView 5.0 in spectra teaching in Analytical Chemistry.Method Undergraduates of Pharmaceutical Science in 2014 grade of Kunming Medical University were selected to teach with a method with the help of Gaussian 09/GuassView 5.0 soft.Calculations of UV spectra,IR spectra and NMR spectra of compounds were introduced to make better understanding in the learning of relative knowledge points.The teaching effect was evaluated by the comparison of theoretical exam results of 2013 grade which didn't use soft.Result The theoretical test results showed that the scoring averages of the 2014 grade in UV,IR and NMR spectra were significantly higher than that in 2013 grade (P＜0.05).Conclusion Gaussian 09/GuassView 5.0 can visualize the nonobjective knowledge,and imporve the students' interesting,thus improving the efficiency of teaching and learning.
RESUMEN
Objective The purpose of this study was to investigate the chemical constituents of Pierre. Methods The chemical compositions were isolated by silica gel column chromatography, semi-preparative HPLC,Sephadex LH-20, and MPLC packed with MCI gel, and their structures were identified on the basis of chemical and spectroscopic evidence (NMR and MS) . Results Eight compounds were obtained and determined as fibraurin (1),makisterone A (2),cycloartenol (3),feruloylphenethylamine (4),trans- -feruloyltyramine(5),β-sitosterol(6),1-monopalmitin(7),1-sinapoyl-β-D-glucopyranoside(8). Conclusion Compounds 2-8 were isolated from this plant for the first time.
RESUMEN
Based on the follow-up investigation made on the employment of university graduates in pharmacy,we analyzed the situation of their jobs,salary and their attitude towards pharmacy and suggested some mothods to promote the graduates employment and give the students the career guidance.Up to now,492 students have graduated,the first employment rate was 78%,and last employment rate was 100%.
