Dear Trish,
Concerning retention of nutrients during frying of vegetables there are many papers on Google Scholar (“nutrient retention frying vegetables”) on the subject (https://scholar.google.dk/scholar?q=nutrient+retention+frying+vegetables&hl=en).
The USDA table/file of for nutrient retention contains general factors for frying of specific vegetables.
The file is a bit difficult to find during the USDA Nutrient Data Base’s transition period to the magnificent FoodData Central (https://fdc.nal.usda.gov/), but I found the one from 2007 (https://www.ars.usda.gov/ARSUserFiles/80400525/Data/retn/retn06.pdf – old link http://www.ars.usda.gov/Main/docs.htm?docid=9448).
The EuroFIR reports on recipe calculations also include tables on nutrient retention. You can find these in Compilers' Toolbox™ under the subject Recipe Calculation (http://toolbox.foodcomp.info/ToolBox_RecipeCalculation.asp) – look for headline EuroFIR reports on recipe calculation and retention factors.
For those of you interested in USDA documents and files, I also found this page where the “old” documents and special databases are listed (https://www.ars.usda.gov/northeast-area/beltsville-md-bhnrc/beltsville-human-nutrition-research-center/methods-and-application-of-food-composition-laboratory/mafcl-site-pages/database-links/).
Hope that USDA ARS will find time to make it easier to find the documents (again) – but fortunately, old hyperlinks are still valid J
For the phytonutrients (VERY broad subject!), I suggest that you consult the EuroFIR eBASIS database (http://ebasis.eurofir.eu/Default.asp) and the Phenol-Explorer database (http://phenol-explorer.eu/). They may have some information, if you do not find the information you need in USDA’s files/databases (see link above).
For the specific nutrient content in the vegetables mentioned, you may want to supply the scientific names to narrow down the possibilities.
All the best,
Anders
