Reyarding Huynh Ngoc Vinh
Vinh has been a student in my lab for 1 semester During that periad he followed an
advanced course in 2D NMR which he passed very well and he did laboratory work
Based on that he wrote a report: “Chemical Constituents of Tithonia Tagetiflora in
Victnam” with a good overview of what was already known The report is short
partly because Vinhs English was not perfect and partly because some of the results
very obtained in the very last part of the stay However, it contains material worth
publishing in an international journal Based on the report he passed two exami at the
end of his stay
Vinh worked well in the laboratory and very hard and proved to be able tu work
independently and he managed to isolate a couple of new and interesting compounds
Vinh has demonstrated an excellent skill in assigning complicated spectra of large
natural products
Vinh showed much progress during his stay in Denmark and he proved to be able to
do good scicnce
