„V. jatamansii is indigenous to the Chinese Himalayas. Geographically, it is distributed from Afghanistan, Kashmir, North-west India, Nepal, Sikkim, North-east India, Bhutan and Myanmar to SW China. It is found within an altitudinal range of 1500m to 3600m on north-facing moist forest bases and in open areas… The demand for Sugandhawal rhizomes and Valerian oil is very high in India and Pakistan. It has been estimated that about 100 tonnes of Sugandhawal rhizomes is harvested annually from Nepal… The global status of Sugandhawal is not known. It is considered to be vulnerable in Nepal (CAMP 2001). Commercial collection of rhizomes for trade poses great threat to its sustainability in the wild.“

„Indian valerian root oil obtained from the roots of the plant V. wallichi collected from different areas has been examined. Neutral portion of the oil contains ar-curcumene, α,β,γ-patchoulenes, patchouli alcohol, β-sitosterol, valeranone, maali-oxide, maaliol, calarene, and the new sesquiterpene hydrocarbon β-bergamotene which is an isoprenologue of β-pinene. Acidic portion of the oil is composed of formic, propionic, butyric, isovaleric, β-methyl valeric, palmitic, steric acids, and isovaleryl ester of α-hydroxyisovaleric acid along with some unidentified acids.“

„The volatile constituents isolated from roots and rhizomes of Valeriana wallichii DC. ( = V. jatamansi Jones) were investigated by GC and GC-MS (EI and NICI) analysis. The plant material was obtained from different sources, namely from a local market in Kathmandu (Nepal), from plants grown in The Netherlands and in Germany, and from commercially available material from several German importers. The various roots and rhizomes yielded between 0.09 and 1.30% (v/w) essential oil on a dry weight basis. The main constituents of the oils from the plants grown in Europe were an unidentified sesquiterpene hydrocarbon, α-santalene, ar-curcumene and xanthorrhizol. In the oils from the Nepalese material and from the commercially available roots, except in one sample, patchouli alcohol was the main component.“

The chloroform extract of V. wallichii roots showed antileishmanial activity, one active ingredient found was caffeic acid bornyl ester.

The major compounds identified in V.jatamansi root oil by GC and GC-MS were patchouli alcohol (0.4-63.7%), maaliol (2.9-53.8%), seychellene (4.1-27.4%), calarene/ß-gurjunene (3.0-20.8%), and α-santalene (0.6-12.0%). Minor constituents were bornyl acetate (0.6-1.5%), α-guaiene (0.7-2.3%), α-bulnesene/δ-guaiene (0.7-6.3%), 7-epi-α-selinene (0.4-1.4%), kessane (2.1-3.3%), spathulenol (0.7-3.4%), viridiflorol (0.9-7.1%), α-patchoulene (0.8-6.6%), and ß-patchoulene (0.4-0.8%).
