“…The results of the study will also help in objective specific improvement, selection and cultivation of the species. The chemotypes identified by Mathela et al (23) are different from the groups identified in our study, which indicates the possibility of the presence of different genotypes under different environmental conditions in the region. The presence of such distinct groups can further be attributed to natural selections under varying environmental conditions prevalent in Himachal Pradesh, India.…”

“…In addition, β-acoradienol was recorded higher in spring season (2.4%). These results are in agreement with the Methela et al (10), who categorized the Valeriana jatamansi in two chemotypes on the basis of presence and absence of patchouli alcohol and maaliol. The presence of patchouli alcohol and the absence of maaliol in this study come under chemotype-II.…”

“…The reports indicated the variation in essential oil composition of V. jatamansi obtained from roots and aerial part (11,16). Similarly, variation in essential oil components of the species among different locations of the Himalayan region is reported (10,12,15). Based on these variations in chemical constituents in essential oil, different morphotypes and chemotypes have been identified (10,15,17).…”

“…Similarly, variation in essential oil components of the species among different locations of the Himalayan region is reported (10,12,15). Based on these variations in chemical constituents in essential oil, different morphotypes and chemotypes have been identified (10,15,17). Moreover, location-specific variation in essential oil constituents showed great variation in its components like patchouli alcohol, α-bulnesene, α-guaiene, guaiol, seychellene, viridiflorol, etc.…”

“…The whole plant is used as a hypnotic and in the treatment of spastic disorder (5,6), anxiety and depression either alone or in combination with other herbs (7,8). Variation in essential oil composition of V. jatamansi has been reported from different part of India (9)(10)(11)(12)(13)(14)(15); however, studies on impact of different cultivation/growing conditions on antioxidant activity of wild and cultivated conditions are poorly known. The reports indicated the variation in essential oil composition of V. jatamansi obtained from roots and aerial part (11,16).…”

d a G. B. Pant institute of himalayan Environment and Development, Kosi-Katarmal, almora, uttarakhand, india; b school of Environment and natural resources, Doon university, Dehradun; c Department of Botany, hamdard university (Jamia hamdard), new Delhi; d Guru Govind singh indraprastha university, Dwaraka, new Delhi ABSTRACTValeriana jatamansi is a perennial medicinal herb used in traditional and modern medicines for preventing number of diseases. Root samples were collected from wild and cultivated conditions in different seasons (spring, summer and winter) and analyzed for essential oil composition using gas chromatography -Mass spectrometry (GC-MS). Antioxidant activity of essential oil was evaluated using DPPH (1, 1-Diphenyl-2-picrylhydrazyl radical) assay. A total of thirty compounds (constitutes 80.1-92.1% of total essential oil) were detected by GC-MS analysis. Patchouli alcohol (36.6-52.8%) was recorded as a major compound followed by guaiene epoxide (3.6-11.5%), seychellene (4.2-5.6%), α-guaiene (2.2-4.6%), kessane (2.7-3.6%), α-patchoulene (0.1-2.3%), β-selinene (0.8-3.1 β-acoradienol (0.6-2.4%), ar-curcumene (0.7-2.2%), γ-patchoulene (1.4-2.6%), viridiflorol (0.6-2.4%), and α-humulene (0.1-4.6%). Essential oil content was recorded higher during winter season in wild (0.9%) and cultivated plants (0.8%) as compared to other seasons. Antioxidant activity of essential oil measured by DPPH radical activity assay varied (IC 50 = 117.5-227.6 μL/mL) among seasons and growing conditions. Winter season is recommended for maximum essential oil yield and spring season for antioxidant activity.

Terpenoids from Essential Oils

Essential oils contain terpenoids and phenylpropanoids as major constituents. Terpene‐bearing aromatic plants play an important role in food, flavor, and fragrance. Essential oils rarely reach the consumers in their natural composition. They are adjusted to meet either the desired quality or specification of a legal regulatory body such as BIS and ISO. The adulterants can be inexpensive synthetic or essential oils of another origin, which ultimately leads to a variable product with less demand. In this article, chiral differentiation using enantioselective gas chromatographic technique is described for high‐value chiral terpenes identified in essential oils. The technique is based on the separation of enantiomers in different cyclodextrin‐coated fused silica capillary columns. The chiral distribution of citronellol enantiomers in Rosa damascena and Cympbopogon winterianus showed the presence of opposite images in each oil. R. damascena contained (−)‐citronellol, whereas (+)‐citronellol was recorded in citronella oil. (+)‐Linalool was a unique feature of Lippia alba . On the contrary, Ocimum basilicum possessed pure (−)‐linalool. Camphor was separated in Ocimum spp. and Cinnamomum camphora with exclusive presence of (+)‐enantiomer. Limonene, menthone, menthol, and menthyl acetate were identified as pure (−)‐enantiomers, whereas isomenthone, neomenthol, pulegone, and piperitone as pure (+)‐enantiomers in Indian menthol mint and peppermint oils, respectively. The usefulness of unique chiral signatures in setting up regulatory guidelines for the most traded essential oils is also discussed.
