from the first look of your analysis data ,it seems you have a penta cyclic component may be one of triterpenoid derivatives. I saw IR and H-NMR and both of them give as some indication about the presence of some functional group like OH , C=O , C=C , CH ,CH2 and CH3. If you check your sample by H-NMR in presence of D2O this will help you to find out the OH or any other group with it's position .

you have to do some more experiments with NMR in order to get complete information about type of C, H and correlations such as DEPT , HSQC, HMBC, COSY, NOESY etc.

Unfortunately, nothing more to say basing on data you gave. Full set of NMR analyses would be of interest. You may also try to obtain a MS spectrum for its trimethylsilyl derivative in a GC-MS analysis - these compounds have quite characteristic mass spectra, at least the most common ones.

Your IR spectrum is of not good quality and data are not enough for an unknown. You should take at least 1H and 13C NMR (and perform 2D experiments for connectivity), perhaps HRMS. Upload these data and hopefully will tell you the structure or guide you to get more info.

Mrs/Miss/Mr. Patil, 

The IR-spectrum is of carboxylic acid (almost 100 % sure), but without mass spectrometric and 13C-NMR data it is unable to identify it unambiguously. Can you provcide these data?!.

If you have not quantity of your substance for 13C-NMR eventually, can you provide tandem MS/MS data!?  

From a first glance, it is not straightforward to identify the compound (or compounds, if it is a mixture in a complex sample). However, a careful analysis of the FTIR spectrum could give relevant indications. This is an excellent (and free) reference for it: http://www.getty.edu/conservation/publications_resources/books/infrared_spectroscopy.html.

Good luck!
