Volatile and aroma profiling of flower and rhizome of growing in North Western Himalayan region.

The present investigation was carried out for a comparative volatile study and aroma profiling of . The headspace gas chromatography mass spectrometry (GC-MS) analysis of flowers (HS-F) and rhizome (HS-R); GC-MS analysis of flower essential oil (EO-F), flower absolute (AB-F) and rhizome essential oil (EO-R) revealed 27, 19, 19, 15 and 12 compounds which constitute 96.22%, 96.93% 97.43%, 86.79% and 97.62% composition, respectively. The identification results demonstrated that flowers and rhizome were rich in -pinene, 1,8-cineol, linalool and --caryohyllene components. -Pinene was the most abundant component in HS-R (38.99%), EO-R (26.61%); linalool in HF-F (25.34%) and EO-F (25.99%) and vinyl-guaiacol in AB-F (32.19%), respectively. The aroma profile of was dominated with floral and jasmine (flowers); spicy, earthy and herbal (EO-F); floral and balsamic (AB-F); herbal, pungent, spicy and earthy (rhizome and EO-R) notes. Based on aroma profile, AB-F was evaluated as potential ingredient for perfume industry.
