1- I suggest the title of paper changes to "Musa paradisiaca L. leaf and fruit peel hydroethanolic extracts improved the lipid profile, glycemic index and oxidative stress in in nicotinamide/streptozotocin-induced diabetic rats".
2- the author mentioned in abstract the dose of extract is 60mg/kg body weight, however, in materials and methods they used 120mg/kg body weight which is write.
3- the authors buitl their discussion the chemicals analysis of extract, however, they not doing this analysis and i suggest the running of this analysis.
4- is suggest for authors ignores the results of kidney function in table 6 because is not compatible with the other results, because it deals manily with liver and its role in detoxification and control the lipid profile and their relation with atherosclerosis and cardiac function.
5- Oxidative stress biomarkers includes free radicals and antioxidant. however, the authors in line 133 writes the supernatants was used for estimation of oxidative stress biomarkers and antioxidants.
6- In addition to some mistakes were marked by yellow colon in the text.

Please not that the level of cardiac enzymes in normal groups is higher than normal range .
