In an effort to determine the chemical diversity of the Valeriana genera of the Northwestern Himalaya (Uttaranchal), V. wallichii, V. himalayana (syn. V. dioica), V. pyrolaefolia, and V. hardwickii var. arnottiana were investigated for their terpenoid compositions by means of GC and GC/MS analyses
The volatile composition of rhizomes of Valeriana wallichii DC has been studied by GC, GC/MS and NMR spectroscopy. Sesquiterpenes were shown to be the main constituents (> 89.3%) comprising kanokonyl acetate (42.4%), gamma-curcumene (10.7%), ar-curcumene (7.2%), (Z)-beta-farnesene (3.2%),
Volatile components in 13 crude drug samples derived from Nardostachys chinensis or Nardostachys grandiflora were studied by solid phase micro extraction (SPME)-GC and SPME-GC-MS. Twenty-three compounds accounting for 81.3 and 70.0% of volatile components in newly collected samples of two species
