The twig essential oil contained α-cadinol (9.8%), terpinen-4-ol (8.4%), oplopanone (8.0%) and epi-α-cadinol (5.0%) and almost no monoterpenes. Indian oils revealed a higher percentage of monoterpenoids in the leaf and berry oils while the twig oil contained sesquiterpenoids as major compounds.

Leaf oil composition of premna barbata wall. ex. sch. from kumaon region of uttarakhand / Chandan S. Chanotiya in The journal of essential oil research, Vol. 21 N°1 (Janvier/Février 2009)

Sch. collected during winter and spring season from Kumaon region has been characterized by GC and GC/MS. A total of about 45 constituents comprising 87–91% of oils have been identified. 1-Octen-3-ol (37.3–21.5%) and epi-α-bisabolol (12.2–14.1%) were the major constituents. The high 1-octen-3-ol content makes the oil biologically active.

Variability in volatile terpenoid compositions of peppermint cultivars and some wild accession from northern India / Rajendra C. Padalia in The journal of essential oil research, Vol. 23 N° 2 (Mars/Avril 2011) 

Public ISBD [article]  in The journal of essential oil research > Vol. 23 N° 2 (Mars/Avril 2011) . - pp. 29-33 Titre : Variability in volatile terpenoid compositions of peppermint cultivars and some wild accession from northern India Type de document : texte imprimé Auteurs : Rajendra C. Padalia, Auteur ; Ram S. Verma, Auteur ; Chandan S. Chanotiya, Auteur Année de publication : 2011 Article en page(s) : pp. 29-33 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Peppermint  Mentha  piperita  L.  Essential  oils  Menthol  Menthone  menthofuran Index. décimale : 646 Résumé : The terpenoid composition of different cultivars of peppermint (Mentha piperita L.) grown in Uttarakhand (India) and accessions collected from wild were analyzed by capillary GC and GC/MS. The major characteristic constituents of all the cultivars and wild accessions were menthol (30.3–47.8%), menthone (4.5–48.6%), menthyl acetate (1.0–9.5%), menthofuran (0.1–14.6%), 1,8-cineole (4.1–8.9%), neo-menthol (1.5–4.9%) and iso-menthone (1.2–3.9%). Although the major characteristic constituents were the same in all oils, there were considerable variations in their quantitative makeup. The contents of menthol and menthofuran were found relatively higher in all cultivars grown in foothills compared to mid-hills. Interestingly, menthofuran, a characteristic compound of the peppermint oil, was detected either at trace level or as a minor component in all the three wild accessions collected from mid-hills. Quality evaluation of peppermint oils revealed that the performance of cultivars grown at foothill conditions are very close to the requirements of European pharmacopoeia as compared to mid-hills.
