Dear All, Can anyone kindly assist in the interpretation of the attached file containing 13C NMR of a newly isolated compound. I need the assistance of an expert in NMR interpretation and structural elucidation of the file attached to this post.
I would gladly welcome your kind assistance. Thanks. You could also contact me via [email protected]
i think your sample is diterpenoid glycoside and total methyls are 5.
if there are 3 methyls it is C3H9 so the total H is 34. But the methyl at 14 is small it could belong to the impurity marked X in the CH2 trace. A regular 13C spectrum would help.
Thank you all for your concern and interest to assist me.
@Uday and John, kindly see the scanned copy of the 1H NMR.
@Clemens and Widyo, I sincerely appreciate your contributions. Thank you so much.
I would be more grateful if anyone could assist me with the structural elucidation.
Kindly let me know if any other information is required.
Thank you.
SIR Okoduwa,
@Dr.Uday Kumar,
The 1H NMR has been uploaded as requested but yet to hear from you
