The study led to the identification and quantification of 34 chemical constituents belonging to different classes of compounds and accounting for 94.2% of the total oil composition. The oil composition is dominated by the presence of monoterpene hydrocarbons (78.9%). The principal components were α-pinene and β-pinene (54.4% and 12.5% respectively) along with limonene (6.5%), γ-terpinene (2.2%), bornyl acetate (2.8%) and α-humulene (4.2%).

Mono-sesquiterpenoid composition in the leaves and flowers of salvia moorcroftiana wall ex Benth. growing wild in kashmir, India / Manzoor A. Rather in The journal of essential oil research, Vol. 23 N° 4 (Juillet/Août 2011)

Bhat, Auteur Année de publication : 2011 Article en page(s) : pp. 21-25 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Salvia moorcroftiana GC GC/MS Monoterpenes Sesquiterpenes (Z)-β  -ocimene β  -caryophyllene Germacrene D Index. décimale : 646 Résumé : In this study, the mono-sesquiterpenoid composition in the leaves and flowers of Salvia moorcroftiana Wall ex Benth is tracked by probing the contents of individual mono- and sesquiterpenoids in the leaf and flower essential oils obtained by hydrodistillation using a combination of GC and GC/MS techniques. Twenty-seven components belonging to different classes of terpenoids and accounting for 94.8% of the total oil were identified in the floral part. Monoterpene hydrocarbons represented the dominant class (68%). (Z)-β-ocimene (54.5%) was the principal component along with sabinene (10.3%), and β-caryophyllene (9.9%). In the leaves only eleven components accounting for 94.4% of the total oil were identified. The leaf essential oil was almost exclusively composed of sesquiterpene hydrocarbons accounting for 87.7% of the total oil. The principal components present were β-caryophyllene (51.6%) followed by germacrene D (18.5%), bicyclogermacrene (7.1%), α-humulene (4.8%) and α-copaene (3.1%).
